2.7 Tire&Wheel
Maintenance of correct inflation pressure (46PSI) is the basic essential factor in obtaining the best
performanceandlifefromapneumatictire.Theairinsidethetireenablesittocarryaload.Itisonly
whentheinflationpressureiscorrectlymatchedthatthetireadoptsitsoptimumcross‐sectionalshape
andthetreadrestscorrectlyontheroadsurfacewiththecorrectpressuredistributionacrossitswhole
width,thusallowingthesidewallstoprovidetherequireddegreeofflexibility.Bothperformanceandlife
ofthetireswillsufferifpressuresareunsuitablesobothoverorunderinflation(oroverloadwhichhas
thesameeffect)aresimilaryundesirable.

Underinflationresultsinexcessivedeflectionwhichincreasestheheatgeneratedbythetire,thisinturn
leadstoitseventualdisintigration.Inadditionthedistortionofthecasingwillresultintheliftingofthe
centreofthetread,thusoverloadingtheouteredgesofthetread,producingrapidwearatthosepoints.

Overinflationdistortsthetire’scasing,butinthiscaseittendstolifttheouteredgesofthetreadoffthe
roadsurfaceandimposesextraloadandmorerapidwearonthecentreofthetread.Owingtoreduced
flexibiltythetirewillbemorevulnerabletoimpactdamage,ridequalitywillbeimpairedandthewheels
willbemoreliabletobouncewhichcanresultinskiddingduetobrakeslocking.

Unlike cars on which tire loads do not vary greatly it is not practicable to provide standard
recommendations.Thisisbecausetireloadingandoperatingconditionsvarywidely.

Remember that spreaders travel laden one way and unladen in the opposite direction, it is therefore
desirable to estabish a suitable mean pressure that mimimises both under inflation when loaded and
excessiveoverinflationwhenrunninglight.
