The purpose of regular tyre rotation
is to achieve more uniform wear for all tyres on a vehicle.
Before you rotate your tyres, consult the vehicle owner's manual for the
manufacturer's rotation recommendation. If no rotation period is specified,
tyres should be rotated every 10,000km. the first rotation is the most
important as it will show the current condition of your tyres.
If there is uneven wear, ask a serviceman to check and correct any
misalignment, imbalance or other mechanical problems before rotation.
