1. Steps for Determining Correct Load Limit— Trailer
Determining the load limits of a trailer includes more than
understanding the load limits of the tires alone. On all trailers
there is a Federal certification / VIN label that is located
on the forward half of the left (road) side of the unit. This
certification / VIN label will indicate the trailer’s Gross Vehicle
Weight Rating (GVWR). This is the most weight the fully
loaded trailer can weigh. It will also provide the Gross Axle
Weight Rating (GAWR). This is the most a particular axle can
weigh. If there are multiple axles, the GAWR of each axle will
be provided.
If your trailer has a GVWR of 10,000 pounds or less, there
is a vehicle placard located in the same location as the
certification label described above. This placard provides tire
and loading information. In addition, this placard will show a
statement regarding maximum cargo capacity. Cargo can be
added to the trailer, up to the maximum weight specified on
the placard. The combined weight of the cargo is provided as
a single number. In any case, remember: the total weight of a
fully loaded trailer can not exceed the stated GVWR.
For trailers with living quarters installed, the weight of water
and propane also need to be considered. The weight of fully
filled propane containers is considered part of the weight of
the trailer before it is loaded with cargo, and is not considered
part of the disposable cargo load. Water however, is a
disposable cargo weight and is treated as such. If there is
a fresh water storage tank of 100 gallons, this tank when
filled would weigh about 800 pounds. If more cargo is being
transported, water can be off-loaded to keep the total amount
of cargo added to the vehicle within the limits of the GVWR
so as not to overload the vehicle. Understanding this flexibility
Not for

will allow you, the owner, to make choices that fit your travel
needs.
When loading your cargo, be sure it is distributed evenly to
prevent overloading front to back and side to side. Heavy
items should be placed low and as close to the axle positions
as reasonable. Too many items on one side may overload
a tire. The best way to know the actual weight of the vehicle
is to weigh it at a public scale. Talk to your dealer to discuss
the weighing methods needed to capture the various weights
related to the trailer. This would include the weight empty or
unloaded, weights per axle, wheel, hitch or king-pin, and total
weight.
Excessive loads and / or underinflation cause tire overloading
and, as a result, abnormal tire flexing occurs. This situation
can generate an excessive amount of heat within the tire.
Excessive heat may lead to tire failure. It is the air pressure
that enables a tire to support the load, so proper inflation
is critical. The proper air pressure may be found on the
certification / VIN label and/or on the Tire Placard. This value
should never exceed the maximum cold inflation pressure
stamped on the tire.
1.1 Trailers 10,000 Pounds (4536 kg)GVWR or less
(1) Locate the statement “The weight of cargo should never
exceed XXX kg or XXX lbs.” on your vehicle’s placard.
(2) This figure equals the available amount of cargo and
luggage load capacity.
(3) Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity.
1.2Trailers over 10,000 Pounds (4536 kg) GVWR
(NOTICE: These trailers are not required to have a tire
information placard on the vehicle.)
(1) Determine the empty weight of your trailer by weighing the
trailer using a public scale or other means. This step does not
have to be repeated.
(2) Locate the GWVR of the trailer on your trailer’s VIN
(Certification) label.
(3) Subtract the empty weight of your trailer from the GVWR
stated on the VIN label. That weight is the maximum available
cargo capacity of the trailer and may not be safety exceeded.
2. Steps for Determining Correct Load Limit—Tow
Vehicle
(1) Locate the statement “The combined weight of occupants
and cargo should never exceed XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and
passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo
and luggage load capacity. For example, if the ‘‘XXX’’ amount
equals 1400 lbs. and there will be five 150 lb passengers in
your vehicle, the amount of available cargo and luggage load
capacity is 650 lbs. (1400–750 (5 × 150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage load capacity
calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehicle. Consult the tow vehicle’s
manual to determine how this reduces the available cargo
and luggage load capacity of your vehicle.

4. TIRE SAFETY - EVERYTHING RIDES ON IT
The National Traffic Safety Administration (NHTSA) has
published a brochure (DOT HS 809 361) that discusses all
aspects of Tire Safety, as required by 49 CFR 575.6. This
brochure is reproduced in part below. It can be obtained and
downloaded from NHTSA, free of charge, from the following
web site:
http://www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/
tires_index.html
Studies of tire safety show that maintaining proper tire
pressure, observing tire and vehicle load limits (not carrying
more weight in your vehicle than your tires or vehicle can
safely handle), avoiding road hazards, and inspecting
tires for cuts, slashes, and other irregularities are the most
important things you can do to avoid tire failure, such as tread
separation or blowout and flat tires. These actions, along with
other care and maintenance activities, can also:
• Improve vehicle handling
• Help protect you and others from avoidable breakdowns
and accidents
• Improve fuel economy
• Increase the life of your tires
This booklet presents a comprehensive overview of tire
safety, including information on the following topics:
• Basic tire maintenance
• Uniform Tire Quality Grading System
• Fundamental characteristics of tires
• Tire safety tips. Use this information to make tire safety a
regular part of your vehicle maintenance routine.
Recognize that the time you spend is minimal compared with
the inconvenience and safety consequences of a flat tire or
other tire failure.
SAFETY FIRST–BASIC TIRE MAINTENANCE
Properly maintained tires improve the steering, stopping,
traction, and load-carrying capability of your vehicle.
Underinflated tires and overloaded vehicles are a major
cause of tire failure. Therefore, as mentioned above, to avoid
flat tires and other types of tire failure, you should maintain
proper tire pressure, observe tire and vehicle load limits,
avoid road hazards, and regularly inspect your tires.
FINDING YOUR VEHICLE'S RECOMMENDED TIRE
PRESSURE AND LOAD LIMITS
Tire information placards and vehicle certification labels
contain information on tires and load limits. These labels
indicate the vehicle manufacturer's information including:
• Recommended tire size
• Recommended tire inflation pressure
• Vehicle capacity weight (VCW – the maximum occupant
and cargo weight a vehicle is designed to carry)
• Front and rear gross axle weight ratings (GAWR – the
maximum weight the axle systems are designed to carry).
Both placards and certification labels are permanently
attached to the trailer near the left front.
UNDERSTANDING TIRE PRESSURE AND LOAD LIMITS
Tire inflation pressure is the level of air in the tire that
provides it with load-carrying capacity and affects the overall
performance of the vehicle. The tire inflation pressure is a
number that indicates the amount of air pressure– measured
in pounds per square inch (psi)–a tire requires to be properly
inflated. (You will also find this number on the vehicle
information placard expressed in kilopascals (kpa), which is
the metric measure used internationally.)
Manufacturers of passenger vehicles and light trucks
determine this number based on the vehicle's design load
limit, that is, the greatest amount of weight a vehicle can
safely carry and the vehicle's tire size. The proper tire
pressure for your vehicle is referred to as the "recommended
cold inflation pressure." (As you will read below, it is difficult
Not for
Reproduction

10 www.allmand.com
to obtain the recommended tire pressure if your tires are not
cold.)
Because tires are designed to be used on more than one type
of vehicle, tire manufacturers list the "maximum permissible
inflation pressure" on the tire sidewall. This number is the
greatest amount of air pressure that should ever be put in the
tire under normal driving conditions.
CHECKING TIRE PRESSURE
NOTICE Check your vehicle's tire pressure at least once a
month for the following reasons:
• Most tires may naturally lose air over time.
• Tires can lose air suddenly if you drive over a pothole or
other object or if you strike the curb when parking.
• With radial tires, it is usually not possible to determine
underinflation by visual inspection.
For convenience, purchase a tire pressure gauge to keep in
your vehicle. Gauges can be purchased at tire dealerships,
auto supply stores, and other retail outlets.
The recommended tire inflation pressure that vehicle
manufacturers provide reflects the proper psi when a
tire is cold. The term cold does not relate to the outside
temperature. Rather, a cold tire is one that has not been
driven on for at least three hours.
When you drive, your tires get warmer, causing the air
pressure within them to increase. Therefore, to get an
accurate tire pressure reading, you must measure tire
pressure when the tires are cold or compensate for the extra
pressure in warm tires.
STEPS FOR MAINTAINING PROPER TIRE PRESSURE
• Step 1: Locate the recommended tire pressure on the
vehicle's tire information placard, certification label, or in
the owner's manual.
• Step 2: Record the tire pressure of all tires.
• Step 3: If the tire pressure is too high in any of the tires,
slowly release air by gently pressing on the tire valve
stem with the edge of your tire gauge until you get to the
correct pressure.
• Step 4: If the tire pressure is too low, note the difference
between the measured tire pressure and the correct tire
pressure. These "missing" pounds of pressure are what
you will need to add.
• Step 5: At a service station, add the missing pounds of air
pressure to each tire that is underinflated.
• Step 6: Check all the tires to make sure they have the
same air pressure (except in cases in which the front
and rear tires are supposed to have different amounts of
pressure).
If you have been driving your vehicle and think that a tire
is underinflated, fill it to the recommended cold inflation
pressure indicated on your vehicle's tire information placard
or certification label. While your tire may still be slightly
underinflated due to the extra pounds of pressure in the warm
tire, it is safer to drive with air pressure that is slightly lower
than the vehicle manufacturer's recommended cold inflation
pressure than to drive with a significantly underinflated tire.
Since this is a temporary fix, don't forget to recheck and
adjust the tire's pressure when you can obtain a cold reading.
TIRE SIZE
To maintain tire safety, purchase new tires that are the
same size as the vehicle's original tires or another size
recommended by the manufacturer. Look at the tire
information placard, the owner's manual, or the sidewall of the
tire you are replacing to find this information. If you have any
doubt about the correct size to choose, consult with the tire
dealer.
TIRE TREAD
The tire tread provides the gripping action and traction that
prevent your vehicle from slipping or sliding, especially when
the road is wet or icy. In general, tires are not safe and should
be replaced when the tread is worn down to 1/16 of an inch.
Tires have built-in treadwear indicators that let you know
when it is time to replace your tires. These indicators are
raised sections spaced intermittently in the bottom of the
tread grooves. When they appear "even" with the outside of
the tread, it is time to replace your tires. Another method for
checking tread depth is to place a penny in the tread with
Lincoln's head upside down and facing you. If you can see
the top of Lincoln's head, you are ready for new tires.
TIRE BALANCE AND WHEEL ALIGNMENT
To avoid vibration or shaking of the vehicle when a
tire rotates, the tire must be properly balanced. This
balance is achieved by positioning weights on the wheel to
counterbalance heavy spots on the wheel-and-tire assembly.
A wheel alignment adjusts the angles of the wheels so
that they are positioned correctly relative to the vehicle's
frame. This adjustment maximizes the life of your tires.
These adjustments require special equipment and should be
performed by a qualified technician.
TIRE REPAIR
The proper repair of a punctured tire requires a plug for the
hole and a patch for the area inside the tire that surrounds the
puncture hole. Punctures through the tread can be repaired
if they are not too large, but punctures to the sidewall should
not be repaired. Tires must be removed from the rim to be
properly inspected before being plugged and patched.
TIRE FUNDAMENTALS
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information
identifies and describes the fundamental characteristics of the
tire and also provides a tire identification number for safety
standard certification and in case of a recall.
Information on Passenger Vehicle Tires
Please refer to Figure 1 and the information following.
Not for

11
1
A- 'P' indicates the tire is for passenger vehicles.
B- This three-digit number gives the width in millimeters of the
tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
C- This two-digit number, known as the aspect ratio, gives the
tire's ratio of height to width. Numbers of 70 or lower indicate
a short sidewall for improved steering response and better
overall handling on dry pavement.
D- "R" stands for radial. Radial ply construction of tires has
been the industry standard for the past 20 years.
E- This two-digit number is the wheel or rim diameter in
inches. If you change your wheel size, you will have to
purchase new tires to match the new wheel diameter.
F-
(Number) This two- or three-digit number is the tire's load
index. It is a measurement of how much weight each tire
can support. You may find this information in your owner's
manual. If not, contact a local tire dealer. NOTICE: You may
not find this information on all tires because it is not required
by law.
(Letter) The speed rating denotes the speed at which a tire
is designed to be driven for extended periods of time. The
ratings range from 99 miles per hour (mph) to 186 mph.
These ratings are listed below. NOTICE: You may not find
this information on all tires because it is not required by law.
Letter Rating Speed Rating
Q 99 mph
R 106 mph
S 112 mph
T 118 mph
U 124 mph
H 130 mph
Letter Rating Speed Rating
V 168 mph*
Y 186 mph*
* For tires with a maximum speed capability over 149
mph, tire manufacturers sometimes use the letters ZR. For
those with a maximum speed capability over 186 mph, tire
manufacturers always use the letters ZR.
G- U.S. DOT Tire Identification Number. This begins with
the letters "DOT" and indicates that the tire meets all federal
standards. The next two numbers or letters are the plant
code where it was manufactured, and the last four numbers
represent the week and year the tire was built. For example,
the numbers 3197 means the 31st week of 1997. The other
numbers are marketing codes used at the manufacturer's
discretion. This information is used to contact consumers if a
tire defect requires a recall.
H- The "M+S" or "M/S" indicates that the tire has some mud
and snow capability. Most radial tires have these markings;
hence, they have some mud and snow capability.
I- Tire Ply Composition and Materials Used. The number of
plies indicates the number of layers of rubber-coated fabric
in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must
indicate the materials in the tire, which include steel, nylon,
polyester, and others.
J- Maximum Load Rating. This number indicates the
maximum load in kilograms and pounds that can be carried
by the tire.
K- Maximum Permissible Inflation Pressure. This number is
the greatest amount of air pressure that should ever be put in
the tire under normal driving conditions.
UNIFORM TIRE QUALITY GRADING (UTQGS)
Quality grades can be found where applicable on the tire
sidewall between tread shoulder and maximum section
width.For example:
TREADWEAR 200 TRACTION AA
TEMPERATURE A
All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades
TREADWEAR
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire
graded 150 would wear one and one-half (1-1⁄2) times as well
on the government course as a tire graded 100. The relative
performance of tires depends upon the actual conditions of
their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and
differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B,
and C. Those grades represent the tire’s ability to stop on
Not for
Reproduction

12 www.allmand.com
wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat
and its ability to dissipate heat when tested under controlled
conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature
can lead to sudden tire failure.The grade C corresponds to
a level of performance which all passenger car tires must
meet under the Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of performance on
the laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately
or in combination, can cause heat buildup and possible tire
failure.
Additional Information on Light Truck Tires
Tires for light trucks have other markings besides those found
on the sidewalls of passenger tires. See Figure 2 and the
information following.
2
A- The “LT” indicates the tire is for light trucks.An “ST” is an
indication the tire is for trailer use only.
B- Load Range. This information identifies the tire’s load-
carrying capabilities and its inflation limits.
C- Maximum Load Dual. This information indicates the
maximum load and tire pressure when the tire is used as a
dual, that is, when four tires are put on each rear axle (a total
of six or more tires on the vehicle).*
D- The "M+S" or "M/S" indicates that the tire has some mud
and snow capability. Most radial tires have these markings;
hence, they have some mud and snow capability.
E- This information indicates the maximum load and tire
pressure when the tire is used as a single.*
*Maximum load is presented in kilograms and pounds (kg/
lbs). Maximum tire pressure is presented in kilopascals and
pounds per square inch (kPa/psi) for when the tire is cold.
Tire Safety Tips
Preventing Tire Damage
• Slow down if you have to go over a pothole or other
object in the road.
• Do not run over curbs of foreign objects in the roadway,
and try not to strike the curb when parking.
Tire Safety Checklist
• Check tire pressure regularly (at least once a month),
including the spare.
• Inspect tires for cracks, foreign objects, uneven wear
patterns on the tread, or other signs of wear or trauma.
• Remove bits of glass and foreign objects wedged in the
tread.
• Make sure your tire valves have valve caps.
• Check tire pressure before going on a long trip.
• Do not overload your vehicle. Check the tire information
placard or owner’s manual for the maximum
recommended load for the vehicle.
