Mazda 626 Owner's Manual page 351

Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperatures can lead to sudden tire
failure.
Grade C corresponds to a level of
performance which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the
minimum required by law.
Form No. 8P95-EA-00G
! 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.
Customer Information

sidewalls of passenger vehicle tires
over the next several years according
