DESCRIPTION AND OPERATION
TIRE INFORMATION
Tires are designed and engineered for each specific
vehicle. They provide the best overall performance
for normal operation. The ride and handling charac-
teristics match the vehicle's requirements. With
proper care they will give excellent reliability, trac-
tion, skid resistance, and tread life.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain in most
cases, much greater mileage than severe use or care-
less drivers. A few of the driving habits which will
shorten the life of any tire are:
• Rapid acceleration
• Severe brake applications
• High speed driving
• Excessive speeds on turns
• Striking curbs and other obstacles
Radial-ply tires are more prone to irregular tread
wear. It is important to follow the tire rotation inter-
val shown in the section on Tire Rotation. This will
help to achieve a greater tread life.

TIRE IDENTIFICATION

Tire type, size, aspect ratio and speed rating are
encoded in the letters and numbers imprinted on the
side wall of the tire. Refer to the chart to decipher
the tire identification code (Fig. 1).
Performance tires have a speed rating letter after
the aspect ratio number. The speed rating is not
always printed on the tire sidewall. The letter S indi-
cates that the tire is speed rated up to 112 mph.
• Q up to 100 mph
• T up to 118 mph
• U up to 124 mph
• H up to 130 mph
• V up to 149 mph
• Z more than 149 mph (consult the tire manu-
facturer for the specific speed rating)
An All Season type tire will have either M + S, M
& S or M–S (indicating mud and snow traction)
imprinted on the side wall.

TIRE CHAINS

Tire snow chains may be used on certain models.
Refer to the Owner's Manual for more information.
