Standards Uniform
TireQual ityGrad ingStandards are
U.S. government specifications. Theirpurpose
is to provid edrivers withuniform reliableinfor-
mation ontire performa ncedata. Tiremanu-
facturers havetograde tiresusing threeper-
formance factors:0043tread weargrade ,0044
traction gradeand0087temperatu regrade .
These regulations donot applyto Cana da.
Neverthele ss,alltires soldinNorth America
are provid edwith thecorrespondi ngqua lity
gradi ngmarkings onthe sidew allofthe tire.
Qual itygrade scan befound, whereapplicable,
on the tire sidew allbetwee ntread shoulder
and maximu msection width.
Example:
R Treadwear grade:200
R Traction grade:AA
R Temperatur egrade: A
All passe ngercartires must conform tothe
statutory safetyrequirements inadd ition to
these grades. i
The

The relative performa nceoftires depends
upon theactual conditions oftheir use,how-

! Avoid
