SERVICE IFE FOR RV/MOTORHOME
TIRES
The following recommendation applies to
RV/Motorhome tires. Tires are composed of various types
of material and rubber compounds, having performance
properties essential to the proper functioning of the tire
itself. These component properties evolve over time.
For each tire, this evolution depends upon many factors
such as weather, storage conditions, and conditions of
use (load, speed, inflation pressure, maintenance, etc.)
to which the tire is subjected throughout its life. This
service-related evolution varies widely so that accurately
predicting the serviceable life of any specific tire in
advance is not possible.
That is why, in addition to regular inspections and
inflation pressure maintenance by consumers, it is
recommended to have RV/Motorhome tires, including
spare tires, inspected regularly by a qualified tire
specialist, such as a tire dealer, who will assess the
tire’s suitability for continued service. Tires that have
been in use for 5 years or more should continue to be
inspected by a specialist at least annually.
Consumers are strongly encouraged to be aware not
only of their tires’ visual conditions and inflation
pressures, but also of any changes in dynamic
performances such as increased gas loss, noise, or
vibration, which could be an indication that the tires need
to be removed from service to prevent tire failure. It is
impossible to predict when tires should be replaced based
on their calendar age alone. owever, the older a tire, the
greater the chance that it will need to be replaced due to
the service-related evolution or other conditions found
upon inspection or detected during use.
While most tires will need replacement before they
achieve 10 years, it is recommended that any tires in
service 10 years or more from the date of manufacture,
including spare tires, be replaced with new tires as a
simple precaution even if such tires appear serviceable
and even if they have not reached the legal wear limit.
For tires that were on an original equipment vehicle
(i.e. acquired by the consumer on a new vehicle), follow
the vehicle manufacturer’s tire replacement
recommendations when specified (but not to exceed
10 years).
The date when a tire was manufactured is located on
the sidewall of each tire. RV owners should locate the
Department of Transportation or DOT code on the tire
that begins with DOT and ends with the week and year
of manufacture. For example, a DOT code ending with
“0304” indicates a tire made in the 3rd week (Jan) of 2004.
THE IMPORTANCE OF TIRE PRESSURE
The most important factor in maintaining the life of
MIC ELIN®RV tires is making sure they are always
properly inflated. Incorrect pressure for the weight
of the vehicle is dangerous and could cause things like
premature wear, tire damage, or a harsher ride.
An underinflated or overloaded tire will build up more
heat that could go beyond the endurance limits of the
rubber and radial cords. This could cause sudden tire
failure. Underinflation will also cause poor handling,
faster and/or irregular tire wear, and can decrease fuel
economy.
Overinflation, on the other hand, will reduce the tire’s
contact area with the road, which reduces traction,
braking ability, and handling. A tire that’s overinflated
for the weight it’s carrying is more prone to a harsh ride,
uneven tire wear, and impact damage.

PRESSURE REQUIREMENT
The amount of pressure required in each tire depends
on the weight of the fully loaded vehicle. So the RV
owners cannot determine the tire’s correct pressure
unless they know their vehicle’s actual weights. The
maximum load capacity allowed for the size tire and load
rating and the minimum cold inflation pressure needed
to carry that maximum load are located on the tire’s
sidewall. The lower the pressure, the lower the load that
the tire can carry. A complete load and inflation table is
available at www.michelinrvtires.com; MIC ELIN®RV
Tires: Guide For Proper Use and Maintenance and RV Tire
Information – MWL43146; and the MIC ELIN®Truck Tire
Data Book – MWL40731.
WHEN TO CHECK RV TIRE PRESSURE
The RV owners need to know the correct pressure per
axle for their RV, and they need to know when and how
often to check the MIC ELIN®RV tires.
ere are a few recommendations for the RV owners:
1) Check at least once a month and before any major
trips.
2) On long trips, check every morning before driving.
3) Check before and after storage.
4) On short trips of a day or less driving each way,
check before you leave and before you return home.
Always try to check tires when they’re “cold” and have
not been driven for more than one mile. The stated load
capacity for a given cold inflation pressure is based on
ambient outside temperatures. The pressure in a “hot”
tire may be as much as 10-15 psi higher than the “cold”
tire pressure. If the RV owners must check the tires when
they’re warm, be sure to allow for an increase in pressure,
and make sure the pressure of the tires on both sides of
the axle are within a couple of pounds of each other.
Never let gas out of a hot tire.
To make checking the tire pressure easier and more
accurate, Michelin recommends that the RV owners
purchase a quality truck tire pressure gauge with a dual-
angled head. This allows the RV owners to check the
pressure of the inner and outer dual wheels. And the
easier it is to check the pressure, the more that the RV
owner will do it. Nothing should restrict the RV owner’s
ability to check their tire pressure daily when driving their
RV. Be sure to use pressure-sealing valve caps to prevent
gas from escaping the valve stem. If the valve stem
extension hoses are used, make sure they’re good quality
stainless steel braid reinforced and are securely anchored
to the outer wheel. The joints should be soaped
immediately after initial installation to check for pressure
loss. If the RV has wheel covers, consider removing them
since the extra time and effort they require could lead the
RV owners to avoid checking the tire’s pressure.
DETERMINING THE RV’S CORRECT
WEIGHT
The GVWR (Gross Vehicle Weight Rating) and the
GAWR (Gross Axle Weight Rating) stickers on the RV
(normally located on the support pillar next to the driver’s
seat) will show the chassis manufacturer’s and/or the RV
manufacturer’s total vehicle weight ratings and per axle
weight ratings.
The GVWR is the maximum total weight rating — this
includes passengers, fluids, and cargo. The GAWR is the
maximum for a single axle.
These ratings can vary
based on a number of
components, so RVs of the
same make and model will
vary because of different
options and personal loads.
That’s why the RV owners
need to weigh their RV in a
loaded condition to know
its actual weight. Michelin
recommends weighing
each wheel position of the
vehicle. Why? Because
when you weigh the entire
vehicle at once, it’s possible to be within the GVWR, but
overloaded on an axle. And when you weigh one axle at a
time, it’s possible for one wheel position to be overloaded
even though the GAWR has not been exceeded (we’ve
seen as much as a 1200-pound difference between left
and right front tires). Weighing each wheel position will
give you a clear indication of how the weight of the RV
vehicle is distributed, so you can determine the correct
tire inflation pressure.
For instructions on how to weigh by wheel position, see
next pages 3-5. Once you know total weight and weight
on each wheel position, the tire load data chart will show
you the correct inflation pressure for each wheel position.

THREE DIFFERENT TYPES OF SCA ES:
1) Platform – Platform scales are usually long enough to weigh the entire vehicle at once.
Michelin suggests the following:
a) Pull onto the scale so that only the front axle is on the platform. The rear end of the
scale needs to be midway between the front and rear axles. Record the weight.
b) Pull forward until the full unit is on the scale. Record the weight.
c) Pull forward until only the rear axle is on the platform. The front end of the scale needs
to be midway between the front and rear axles. Record the weight.
d) If the RV has a rear tag axle, pull forward so only tag axle is on the scale. Record the
weight.
e) To determine individual wheel position weights, repeat steps (a) through (d) with only
one side of the vehicle actually on the scale and the vehicle centered over the side of
the scale. See diagram on next page. Record the weights.
f) To calculate the opposite wheel positions’ weights, subtract the weights recorded in step
(e) from the weights recorded in steps (a) through (d). If there is not a towed vehicle, the
tag axle weight derived from (d) will represent the actual weight on the tag axle.
g) If a vehicle is being towed, it should be weighed and combined with the GVW (Gross
Vehicle Weight) to ensure the total weight doesn’t exceed the GCWR (Gross Combined
Weight Rating).
2) Segmented Platform – Platform scales with segmented sections can provide individual
axle weights and total vehicle weights all at once when the vehicle is positioned properly.
To do this, simply:
a) Position the vehicle on the scales so that each axle is centered as much as possible on
the segments, and record the weight.
b) Reposition the vehicle so that only one side is on the scale – centered on the segment
as much as possible.
c) Subtract the weighed wheel positions from the total axle weights to determine the
unweighed wheel position weights.
3) Single Axle – Weighs one axle at a time.
Follow these steps:
a) Drive the front axle onto the scale and stop long enough for the weight to be recorded.
b) Pull vehicle forward until the rear axle is on the scale.
c) For gross vehicle weight, add the two axle weights together.
d) To obtain the individual wheel position weights, repeat this process with only one side
of the RV on the scale.
Note: Even though the weight of the total axle is within the axle rating, it may be overloaded on
one side, which means an overloaded wheel position. That’s why side-to-side weighing is
required.

NOTE: Michelin recommends using a professional weighing group or organization to perform the weighing of your
Motorhome/RV. The Recreational Vehicle Safety Foundation (RVSEF) is an organization that performs weighing and other
educational services. They can be contacted at www.rvsafety.com. If you are planning to do your own weighing, you should
follow the procedures below. Michelin recommends checking with the scale operator to make sure there are no concerns on
damage to the scale or to the vehicle if weighing side to side to determine individual wheel position weights.
HOW TO WEIGH THE RV
First, the RV must be weighed fully loaded — that includes passengers, food, clothing, fuel, water, propane, supplies, and
anything else you can think of. Also, any towed vehicle (car, boat, or trailer) or item loaded on brackets on the back of the
RV (like bikes or motorcycles) should be included in the weighing.

TO OBTAIN INDIVIDUA WHEE POSITION WEIGHTS
The RV must remain as level as possible on the scale (even when an axle or side isn’t on the scale). Therefore, to
obtain side-to-side weights, there must be enough space on either side of the scale to accommodate the RV being
partially off the scale.
If there is a difference in the weights on one side of the vehicle as compared to the other, it is important to
redistribute the load more evenly to avoid component failure and improve handling. These weights make it possible
to compare against the GAWR (Gross Axle Weight Rating), GVWR (Gross Vehicle Weight Rating), and tire capacities.
They also help determine proper tire pressure.

THE EFFECT OF TOWED VEHIC ES OR TRAI ERS
If your RV is towing a vehicle, you need to know the RV’s GCWR (Gross Combined Weight Rating), the total actual
loaded weight of the RV, plus the total actual loaded weight of the towed vehicle. Even though the GCWR has more to
do with the design limits of the drivetrain (engine, transmission, axle, brakes, and bearings), the additional weight can
also affect the tires and the RV’s handling. Also, always remember to consider the tongue weight of the trailer and its
effect on handling.

6MICHELIN®RV Tires
When using blocks to level motorhomes or
RVs, extreme caution must be taken to make
sure the tires are fully supported. The weight
on the tire should be evenly distributed on the
block. And in the case of duals, it should be
evenly distributed on blocks for both tires. If
not, the sidewall cables can become fatigued
and damaged, resulting in a sidewall rupture
and a complete, sudden loss of pressure.
Note in the correct method, the blocks
are wider than the tread and longer than the
tire’s footprint. This provides maximum
support to the tires and assures that the load
is evenly distributed.
Let’s consider an RV running on 275/80R22.5
MIC ELIN®XZA3®+EVERTREAD LRG tires, with actual
corner weights of 5,400 lbs. on the left front tire,
5,175 lbs. on the right front tire, 8,500 lbs. on the left
rear duals, and 9,200 lbs. on the right rear duals. For
control of the RV, it is critical that the tire pressures be
the same across an axle. Therefore, we must “overinflate”
the right front tire and the left rear duals. Checking the
load/inflation table below shows that a cold tire pressure
of 95 psi will support 5,510 lbs. on a single front tire.
To determine the pressure for the rear duals, again
take the heaviest position, in this instance the right rear
weighs 9,200 lbs. The load/inflation table below shows
that a cold pressure of 85 psi will support 9,380 lbs. on
2 dual tires. It is important to note that the cold inflation
pressure for the tire must never exceed the maximum
inflation rating that is stamped on the wheel.
REMEMBER: For control of the RV, it is critical that the
tire pressures are the same on both sides of an axle.
Please note that the standard MIC ELIN
load/inflation charts have been altered for RV usage only.

MICHELIN®RV Tires 7
AGING, WEATHER CHECKING, AND
OZONE CRACKING
During the pre-trip inspection, be sure to check the
tires for signs of aging, weather checking, and/or ozone
cracking — these show up as tiny cracks in the rubber
surface on the sidewall of the tire. If the cracks are less
than 1 ⁄32" deep, the tire is fine to run. Between 1⁄ 32" and
2⁄32",the tire is suspect and should be examined by the
MIC ELIN dealer. If the cracks are any deeper than
2⁄32",the tire should be replaced immediately.
ere are a few tips to help you protect the tires from
these common damage conditions:
1) Keep the tires properly inflated.
2) Keep the tires clean.
3) Avoid prolonged exposure to heat, cold, or moisture.
4) Avoid prolonged exposure to ultraviolet rays.
5) Cover the tires when the vehicle is not in use.
6) Do not park near electric generators or transformers.
7) Do not store vehicle in an area where welding is being
done or in a garage that has mercury vapor lamps.
ONG TERM STORAGE OF RV TIRES
Unless the RV owner is a full-time RV-er, the vehicle
probably spends some time in long-term storage. But
what the RV owner probably didn’t know is that rubber
tires age when not being used. So, if the owner must store
the RV, a cool, dry, sealed garage is the best bet. Also, some
storage surfaces can cause tires to age faster. That’s why
Michelin recommends placing a barrier (cardboard,
plastic or plywood) between the tire and the storage
surface.
ere are some other steps the RV owner can take to
help reduce the aging effects from long-term storage:
1) Thoroughly clean tires with soap and water before
placing into storage.
2) Cover tires to block direct sunlight and ultraviolet
rays.
3) Store out of a high ozone area.
Note: When a vehicle is stored, tires should be inflated
to the inflation pressure indicated on the sidewall.
Before removing the vehicle from long-term storage,
thoroughly inspect each tire – this includes sidewalls,
tread area, and pressure. If the tires have lost pressure, be
sure to inflate them to the correct pressure before driving.
PROPER C EANING OF RV TIRES
Like the rest of the RV, it pays to keep the MIC ELIN®
tires clean. Road oil will cause deterioration of the rubber,
and dirt buildup will hold the contaminants next to the tire.
As with the cleaning of any rubber product, proper
cleaning methods must be used to obtain the maximum
years of service from the tires. A soft brush and the
normal mild soap that you would use to clean the RV
may be used. If you use a dressing product to “protect”
the tires from aging, use extra care and caution. Tire
dressings that contain petroleum products, alcohol, or
silicones will cause deterioration or cracking and
accelerate the aging process.
In many cases, it is not the dressing itself that can be
a problem, but rather the chemical reaction that the
product can have with the antioxidant in the tire. eat
can add to the negative reaction. When these same
dressing products are used on a passenger car tire that is
replaced every three to four years, it is rare to see a major
problem. owever, in most cases, RV tires may last much
longer due to limited annual mileage, and the chemical
reactions have much longer to take place.
TIRE REPAIR
Even the best drivers can drive over a nail, and the best
tires can pick up that nail or screw and go flat. If you pick up
an object that causes a flat with a MIC ELIN®RV tire, the
repair must be made to the inside of the tire to be repaired
properly. To do this, the tire needs to be demounted and
inspected on the inside of the casing for any other damage
that the object may have caused. See the MIC ELIN®truck
tire dealer for the proper repair and damage inspection.
TIRE INSPECTION
The MIC ELIN®RV tires should be inspected
thoroughly at least once a year, and any time the owner
drives in rough or rocky terrain, or when the owner is
having their RV serviced. This inspection should include
both sidewalls, the tread area, and the valves, caps, and
any valve extensions. Inspect for nails, cuts, bulges, aging,
or fatigue cracks and weathering or ozone cracking. Also,
check between the duals for objects lodged between
them. See the MIC ELIN®dealer at once if anything
unusual is observed.
On a regular basis, rub the palm of your hand across the
face of the tread on your front tires to feel for any feathered
wear from “toe” alignment problems. NOTE: Be careful
since severe wear can expose steel belt edges that are very
sharp. A “toe” misalignment problem can be caused by
impact with a “chuck” hole in the road. Bad “toe” wear can
be hard to find visually, but can be felt very quickly with the
hand. This type of alignment problem can wear rubber off
the tread of the tires in just a few hundred miles.
MAINTAINING MICHE IN®RV TIRES

No tire, regardless of its quality, is indestructible.
Certain conditions of use and abuse can stress a tire
beyond reasonable operating limits, causing it to come
out of service even when considerable tread remains.
Such conditions are clearly indicated by the damage they
leave on the tire itself. Listed below are some common
damages and the signs they leave behind. Please
understand that this list is by no means exhaustive
and is intended only as a general guide.
UNDERINF ATION
This condition is often referred to as a “run-flat” tire.
It is caused by operating a tire at very low or zero
pressure. When a tire is run at normal highway speeds,
underinflated, it flexes too much and builds up heat.
This heat damages the inner liner, casing, and outer
sidewall of the tire. If not remedied quickly, the tire will
be irreparably damaged.
In extreme cases, the sidewall of the tire is destroyed,
from the excessive heat and the weight of the vehicle
crushing/cutting the tire against the wheel as it rolls on
the uninflated sidewall. According to guidelines put out
by the Rubber Manufacturers Association (RMA), any tire
that has been run at less than 80% of normal
recommended pressure for the load it is carrying should
be inspected for possible damage.
When one tire in a dual configuration comes out of
service due to under-inflation/run-flat damage, the
other tire in the dual configuration should be inspected
immediately. If the unserviceable tire was underinflated,
that means the serviceable tire was carrying more and
more of the load for that wheel position. Consequently,
it too may have suffered some casing damage.
FATIGUE RUPTURE
This type of damage is sometimes called a “zipper rip”
because of the zipper-like effect it creates in the steel
casing cords of the damaged tire. When a casing cord is
damaged or repeatedly and excessively bent due to over-
load and/or underinflation, it will eventually break and
subject the cords on either side to even more stress.
When enough strength has been lost due to additional
cord breakage, a rupture occurs and can progress rapidly
along the path of least resistance in the upper sidewall.
This can happen hours, days, or even months after the
initial damage event when all evidence or memory of the
initial damage or overload/underinflation is gone.
Casing cords in the MIC ELIN®truck tires used on
motorhomes are very strong twisted steel cables.
Extreme over-deflection of a tire, that can occur during
improper blocking of tires or high energy impacts, may
weaken the structure of the cable so as to make it less
tolerant of the repeated bending stress encountered in
normal use. If in addition, the integrity of the steel cords
is degraded by corrosion from moisture reaching the
cords through cuts or tears in the rubber, their tolerance
of these conditions will be even further reduced. This
corrosion may result from mounting damage, foreign
objects left inside the tire, road hazards, tire
mishandling, or even improper repair of a nail hole.
DUA KISSING
While somewhat romantic in name only, this type of
damage refers to what happens when two tires in dual
configuration make contact with each other while in
operation. The heat generated by the friction between
the two tires severely weakens the casing material of the
dual tires. This is easily seen on the sidewalls of the tires
where the duals came in contact. The condition may be
caused by several factors:
- improper mounting
- incorrect wheel width or offset
- underinflation
- “casing growth”
In this last case, the fabric casing cords of the tire
actually stretch and expand, causing the tire to touch
or kiss, under load at the contact patch.

TIRE WEAR, BA ANCE, AND WHEE
A IGNMENT
All tires mounted on RVs should wear in a smooth,
even wear pattern when the tires are maintained with
the correct pressure for the load on the tire. If tires begin
to show an irregular wear pattern, and the vehicle
alignment is correct, sometimes just rotating the tires
to change direction of rotation and wheel position will
allow the tires to wear evenly.
Significant tire and wheel assembly imbalance may
cause steering difficulties, a bumpy ride, and worn spots
on your tires. It is recommended that tire and wheel
assemblies be inspected and balanced if one of these
conditions exists.
Check with the motorhome chassis manufacturer
for the correct alignment specifications. Michelin
recommends, for optimized radial tire life and
performance, that the “toe-in” setting should be as
close as is practical to zero, within the motorhome
manufacturer’s specifications. The caster should be set
to the maximum positive or minimum negative setting
within the tolerances specified by the manufacturer.
Toe Wear
A feathered wear pattern on the front tires typically
indicates misalignment (toe-in or toe-out). Sometimes
a radial tire will not have this wear pattern unless the toe
condition is severe. Instead of the feathered edge wear,
the tire will be worn on the inside or outside shoulder,
which could be confused with camber wear.
On a three-axle RV, a skewed rear axle and tag could
cause feathered edge wear on one shoulder of one front
tire and feathered edge on the opposite shoulder of the
other front tire. In order to correctly diagnose a tire wear
condition, the motorhome should have the alignment
checked on all wheel positions.
Camber Wear
Also known as edge wear, camber wear shows up on
the inside or outside shoulders of the tread. Wear on the
inside edge of both tires may be due to negative camber
or toe-out, a misalignment. If only one tire shows edge
wear, check for worn kingpin bushings, bent or worn
steering components, or excessive positive camber.
For solid beam axles, excessive camber can result from
axle over-load.
Tire Rotation
If correct pressure and proper alignment are both
continually maintained, tire rotation may never be
needed. owever, in other cases, tire rotation may be
needed to help even out wear patterns caused by
alignment, underinflation, or free-rolling wear problems.
Follow the motorhome manufacturer’s rotation service
recommendations. There are no restrictions as to the
method of rotation with the MIC ELIN®RV tires; however,
Michelin recommends including the spare tire in the
rotation pattern and changing the direction of rotation.
Tires can be rotated front to rear and side to side. If using
directional tires, ensure tires are mounted to rotate in
proper direction as it may contribute to premature wear.

SE ECTING REP ACEMENT TIRES FOR THE RV
One of the most important RV equipment purchases
that the RV owner will make will be the replacement tires.
If they obtained good service with their first set of tires,
chances are that they were matched well for the RV’s
weight needs and the RV owner type and area of driving.
Should the RV owner choose to replace their tires with
another size, be very careful with this selection. There are
some basic areas of concern, such as the load rating of
the new tire and the overall diameter of the new tire for
vehicle clearance, speedometer reading, and wheel
width.
There is also the matching of the tires to the dual
wheel offset for the dual spacing clearance and the load
rating of the wheel. For example: buying a tire with a
higher load rating that might require 105 psi would be
inappropriate if the RV wheel is limited to 80 psi.
(Be sure that the wheel width is compatible with the
new tire size; doing otherwise is dangerous.) Consult
the vehicle manufacturer for wheel specifications.
If the RV owners have already been driving on
MIC ELIN®RV tires, they are aware of some of Michelin’s
extra benefits, such as the great wet and dry traction and
outstanding handling. Most RV owners who drive on
MIC ELIN®tires for the first time comment on the
smooth, quiet ride.

VIBRATION COMP AINT
When a motorhome owner comes in with a vibration
complaint, contact the appropriate chassis and
motorhome manufacturers to establish an incident
report and get possible motor-home warranty handling
instructions. The following procedure should take care of
most complaints.
1. Driver interview — this should include the following:
– has this vehicle been worked on by the chassis
manufacturer or MIC ELIN®dealer for this
complaint?
– type of complaint
– driving and road conditions when the vibration
occurs - mph/rpm acceleration/deceleration
– when in the life of the vehicle did it begin?
– where does the vibration seem to be coming from?
Front or rear?
– recent maintenance or modifications to the vehicle
2. Vehicle test drive - ride in the vehicle and have the
owner demonstrate the complaint to you to verify
that there is in fact a problem.
Include the following observations:
– speed at onset of vibration and the speed range
– does the vibration phase in and out, or is it
constant?
– sensitivity to road surface? Smooth roads? Rough
roads? Both?
– effects of acceleration/deceleration/constant speed
– is vibration felt through the seat? Floor? Steering
wheel? Other?
– is this a ride quality or a drive train vibration
complaint?
3. Complaint history
– check all motorhome warranty records, etc., to
determine past history of the same or similar
complaints on this vehicle
– have there been any changes or modifications to
the chassis since manufacturing?
– has any prior effort been made to diagnose or
correct the complaint? By whom?
VIBRATION DIAGNOSIS
If the vibration seems to be driveline related and from
the wheel ends, then perform the following:
Tire and wheel assembly inspection
1. Jack up the front of the vehicle and spin each
assembly, observing the wear conditions of each tire
and concentricity of the
tire on wheel mounting.
If the variation in the
distance between the
line-up (“gg”) ring and
the wheel flange exceeds
1⁄16",have the assembly
broken down, relubed,
and remounted (see diagram).
2. Measure and record the radial runout on the vehicle
of each assembly with tire runout gauge. Mark the
highest point of the assembly. Rotate each assembly
until the high spot is at the 12:00 position (without
allowing the assembly to turn). Loosen all lug nuts
and re-torque in the proper sequence. Re-measure
and record the radial runout of the assembly.
If either front assembly still exceeds 0.040",measure
the rear assemblies and put the two assemblies with
the least runout on the steer axle.
3. Repeat the vehicle test drive. If the vibration still
exists, contact the appropriate chassis manufacturer.

18 MICHELIN®RV Tires
For RV use only, Michelin displays tire loads per axle end in the load and inflation tables, as we recommend weighing
each axle end separately and using the heaviest end weight to determine the axle's cold inflation tire pressure. For control of
your RV, it is critical the tire pressures be the same across an axle, while NEVER exceeding the maximum pressure limit
stamped on the wheels.
To select the proper load and inflation table, locate your tire size in the following pages, then match your tire's sidewall
markings to the table with the same sidewall markings. If your tire's sidewall markings do not match any table listed,
please contact your Michelin dealer for the applicable load and inflation table.
Industry load and inflation standards are in a constant state of change, and Michelin continually updates its product
information to reflect these changes. Printed material may not reflect the latest load and inflation standards.
In the load and inflation tables, SING E means an axle with one tire mounted on each end, while DUA means an axle
with two tires mounted on each end. In an RV application, the loads indicated represent the total weight of an axle
end. When one axle end weighs more than the other, use the heaviest of the two end weights to determine the unique
tire pressure for all tires on the axle. The maximum cold pressure for each axle may vary, depending on their weights.
These tables are applicable for all RV axles, whether or not they are power-driven.
