Rotate tyres periodically:
Irregular tyre wear is dangerous. To equalize tread wear for maintaining good performance in handling and braking, rotate the tyres every 10,000 km (6,250 miles), or sooner if irregular wear develops.
During rotation, inspect them for correct balance.
Also, inspect them for uneven wear and damage. Abnormal wear is usually caused by one or a combination of the following:
Incorrect tyre pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tyre pressures to specification (Search) and inspect the wheel nuts for tightness.
Rotate unidirectional tyres and radial tyres that have an asymmetrical tread pattern or studs only from front to rear, not from side to side. Tyre performance will be reduced if rotated from side to side.
