The interval
Follow the interval in your owner's manual. Many manufacturers suggest roughly every 8,000 to 10,000 km, often lined up with oil changes. If you run separate winter and summer sets, rotating at each seasonal changeover is an easy way to stay on schedule.
Why tires wear at different rates
The front tires on most cars steer and carry the engine's weight; on front-wheel-drive cars they also put down the power. They wear faster than the rears. Rotating spreads that wear across all four, so the set reaches its replacement point together instead of two at a time.
Common rotation patterns
The right pattern depends on the vehicle and the tires:
- Front-wheel drive: fronts straight to the rear; rears cross to the front.
- Rear-wheel drive and most 4x4s: rears straight to the front; fronts cross to the rear.
- Directional tires (arrow on the sidewall): front to back on the same side only.
- Different sizes front and rear: side to side only, if the tires aren't directional.
All-wheel drive
AWD systems are sensitive to differences in tread depth between tires, because the drivetrain sees a smaller tire as one that's spinning faster. Regular rotation keeps the four close together. Many vehicle manufacturers specify a strict maximum tread variance across axles; check your manual for exact tolerances.
Rotation and balance
Balance stays with the wheel, so a rotation doesn't normally need rebalancing. If a vibration appears after a rotation, a weight has likely come off and that wheel should be rebalanced. Rotation also moves any existing wear pattern to a new position, which is a good moment to look for uneven wear.
