TireQuality Grading Standards areU.S.
governmen tspecifications. Theirpurpose isto
provide driverswithuniform reliableinformation
on tire performance data.Tiremanufacturers
have tograde tiresusing threeperformance fac-
tors: 0043tread weargrade, 0044tract iongrade and
0087 temperature grade.Theseregulations donot
apply toCanada. Nevertheless, alltires soldin
North America areprovided withthecorre-
sponding qualitygrading markings onthe side-
wall ofthe tire.
Quality gradescanbefound, whereapplicab le,
on the tire sidewal lbetween treadshoulder and
maximum sectionwidth. Example:
R Tread weargrade: 200
R Tra ction grade: AA
R Temper aturegrade: A
All passenger cartires must confor mto the stat-
utory safety requirements inaddition tothese
grades.
i The
actual values fortires arevehicle-spe-
cific andmay deviate fromthevalues inthe

Tread wear The

under controlled condition son aspecified U.S.
governmen tcourse. Forexample, atire graded

on the governmen tcourse asatire graded 100.
The relative performance oftires depends upon
the actual condition sof their use,however, and
may depart significantly fromthenorm dueto
variations indriving habits, service practices
and differences inroad characterist icsand cli-
