11-34 Maintenance and service

When you install a tire that has the tire

rotation direction mark, install the tire with

the direction mark facing forward.

Tire wear varies from wheel to wheel. To

maximize the life of each tire and ensure

that the tires wear uniformly, it is best to

rotate the tires every 7,500 miles (12,500

km). Move the tires to the positions shown

in the illustration each time they are

rotated.

Replace any damaged or unevenly worn

tires at the time of rotation. After tire

rotation, adjust the tires pressures and

make sure the wheel nuts are correctly

tightened.

After driving approximatel y 600 miles

(1,000 km), check the wheel nuts again

and retighten any nut that has become

loose.

& Tire replacement

The wheels and tires are important and

integral parts of your vehicle’s design;

they cannot be changed arbitrarily. The

tires fitted as standard equipment are

optimally matched to the characteristics

of the vehicle and were selected to give

the best possible combination of running

performance, ride comfort, and service

life. It is essential for every tire to have a

size and construction matching those

shown on the tire placard and to have a

speed symbol and load index matching

those shown on the tire placard.

Using tires of a non-specified size detracts

from controllability, ride comfort, braking

performance, speedometer accuracy and

odometer accuracy. It also creates incor-

rect body-to-tire clearances and inappro-

priately changes the vehicle’s ground

clearance.

All four tires must be the same in terms of

manufacturer, brand (tread pattern), con-

struction, and size. You are advised to

replace the tires with new ones that are

identical to those fitted as standard equip-

ment.
