WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, see “Changing wheels and tires” (P. 8-41). Many factors including tire inflation, alignment, driving habits and road conditions

mean your tires will last that long. Use the tire replacement indicator as a guide only and always perform regular tire checks.
Failure to perform regular tire checks, including tire pressure checks could result in tire failure. Serious vehicle damage could
occur and may lead to a collision, which could result in serious personal injury or death.
