Tire rotation is essential to achieve even tread wear and maximum tread life. On front-wheel-drive cars, for example, most of the braking, steering and driving forces are carried by the front tires, which inevitably wear much faster.
A "cross-rotation pattern"—that is, moving the left-front tire to the right-rear axle, the right-front tire to the left-rear axle, etc.—can best balance tread wear and maximize tire life. That sequence can be performed on any vehicle equipped with four non-unidirectional tires. Designated by an arrow on the sidewall, unidirectional tires must be rotated only front to rear and rear to front, on the same side of the vehicle, so their direction of revolution does not change.
All-wheel-drive and four-wheel-drive vehicles are best suited to a lateral rotation—left to right and right to left—at the same end of the vehicle.
