Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Here are some important maintenance points:
Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires
are cold. Maintain recommended pressures for the best ride, top han-
dling, and minimum tire wear. Use the pressures specified on the
vehicle tire information placard or tire label for optimum service.
Tire Rotation
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Inspect the tires for uneven wear and damage. Abnormal wear is usu-
ally caused by one or a combination of the following:
• Incorrect tire pressure
• Improper wheel alignment
• Out-of-balance wheel
• Severe braking
After rotation, inflate all tire pressures to specification (→P. 558) and
inspect the lug nuts for tightness.
NOTICE
Rotate unidirectional tires and radial tires that have an asymmetrical
tread pattern or studs only from front to rear, not from side to side. Tire
performance will be weakened if rotated from side to side.
