Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “What To Do In Emergencies” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause tire damage or failure. A tire could explode and injure someone. Do not
spin your vehicle's wheels faster than 30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not let anyone near a spinning wheel, no
matter what the speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom of the tread grooves. They will appear as
bands when the tread depth becomes a 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon varying factors including, but not limited to:
• Driving style.
• Tire pressure – Improper cold tire inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal wear patterns will reduce
tread life, resulting in the need for earlier tire replacement.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these tires per the vehicle maintenance
schedule is highly recommended.
WARNING!
Tires and the spare tire should be replaced after six years, regardless of the
remaining tread. Failure to follow this warning can result in sudden tire failure.
You could lose control and have a collision resulting in serious injury or death.
Keep dismounted tires in a cool, dry place with as little exposure to light as possible.
Protect tires from contact with oil, grease, and gasoline.
