depend on factors such as inﬂation pressure, load, tire

condition, wear, and driving conditions.

** Any tire having a maximum speed capability above 149 mph

(240 km/h) may, at the tire manufacturer’s discretion, include

a “Z” in the size designation (i.e. P275/40ZR17).

*** For tires having a maximum speed capability above 186

mph (300 km/h), a “Z” must appear in the size designation

and a “Y” marked in brackets (as shown) in the service

description.

**** Consult the tire manufacturer for maximum speed

capability.

TIRE SPINNING

SAFETY WARNING

Spinning a tire to extract a vehicle stuck in mud, ice, snow, or

wet grass can be dangerous. A tire spinning at a speedometer

reading above 35 mph (55 km/h) can in a matter of seconds

reach a rotation speed capable of disintegrating a tire with

explosive force. Under some conditions, a tire may be spin-

ning at a speed twice that shown on the speedometer. This

could cause serious personal injury or death to a bystander or

passenger. Never spin a tire above a speedometer reading of

35 mph (55 km/h).

RADIAL TIRE ROTATION

The purpose of tire rotation is to minimize irregular or uneven

wear caused by maintaining a tire in one rotation direction and

one position over an extended period. Rotate tires as rec-

ommended by the vehicle manufacturer or every 5,000 miles

(8,000 km). Individual tire pressures must be checked after

rotation and adjusted to the vehicle manufacturer’s recom-

mendation for the tire’s new location on the vehicle. Vehicle

alignment should be checked if irregular wear is evident.

For vehicles with a “temporary use” spare tire, follow the

vehicle manufacturer’s recommended pattern for rotation,

or, if not provided, the following may be used:

If your spare is the same size, load rating, and type of tire

as your road tires, it should be included in the tire rotation

process. For vehicles with a “full-size” spare, the following

rotation patterns may be used:
