Tire rotation

Tire Guy

Sometimes irregular tire wear can be corrected by rotating your tires. Consult your vehicle's owners manual, the tire manufacturer or your tire dealer for the appropriate rotation pattern for your vehicle. NOTE: If your tires show uneven wear, ask your tire dealer to check for and correct any misalignment, imbalance or other mechanical problem involved before rotation.

Before rotating your tires, always refer to your car's owner's manual for rotation recommendations. If no rotation period is specified, tires should be rotated approximately every 6,000 miles.

Tires should be rotated as instructed in the vehicle owner manual to realise their full potential. Rotation is essential to tires for long, even tread wear, Good driving habits also extend tread life. Rotation is advisable whenever irregular wear begins to develop. In such circumstances, determine the cause of the irregular wear and make any necessary adjustments to wheel balance, alignment, or any other mechanical problems before rotating the tires. Irregular wear may also uncover poor driving habits. Customers should be properly advised if irregular wear is due to poor driving habits. Under normal conditions, be sure to follow the recommended rotation procedures in the vehicle owner manual. Tyre inspection for nails, cuts, and other damage should also be carried out at the time of tyre rotation.

Rotation intervals are determined as part of the vehicle design between the auto maker and the tyre manufacturer, so following the vehicle owner manual is important. Several rotation patterns exist for passenger car tires. However, for HPTs, including unidirectional and asymmetric tread patterns, Yokohama recommends the rotation patterns shown in figure 27 in the absence of a vehicle owner manual. The rotation interval depends on the tyre condition and the expected tyre life.

Yokohama recommends rotation intervals of 5,000 kilometres (3,000 miles) for 4WD and sport cars, and 12,000 kilometres (7,500 miles) for other vehicles.


Wheel Rotation

Recent studies have shown that the front tires of a front wheel drive car may wear twice as fast as the rear tires because of vehicle weight distribution imbalance, so more frequent tyre rotations are desirable due to resultant differences in tread wear between wheel positions. Accelerated wear is caused by three effects:

One: Front tires incur more "scrub" during steering and cornering.
Two: The front tires (FWD) absorb the acceleration drive torque.
Three: The front tires (FWD) absorb most of the vehicles weight while braking. Additionally, the rear tires (free rolling wheels) may develop uneven wear because of the lack of drive torque and braking forces that assist smooth tyre wear. Therefore a proper tyre rotation schedule is highly recommended for front wheel drive vehicles.
