TIRE CODING
TIRE CONDITION
Traction The traction grades, from highest to low

est, are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified govern

A tire marked C may have poor traction per

The traction grade assigned to this tire is based on straight-ahead brak

dissipate heat when tested under con

trolled conditions on a specified indoor lab

oratory 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 Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the labora
-
tory test wheel than the minimum required
by law.
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 fail

The vehicle or the jack could slip sideways
