or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.

■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even

■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.1 0 of the
replacement tire is greater than 1/2 of the Gross Axle Weight R atings
(GAWR) of either the front axle or the rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. ( P. 5 2 9 )
