Rotating your tyres periodically is an important part of tyre maintenance. The main purpose of regularly rotating tyres is to achieve more uniform wear for all tyres on the vehicle.
If no rotation period or pattern is to be found in your owner's documentation, rotate your tyres at least every 8.000 to 10.000 km. However, rotate your tyres earlier if irregular or uneven wear develops, and check with a qualified tyre dealer or alignment shop to determine the cause of the wear problem. Remember that a hard impact such as hitting a pothole can cause misalignment, which then causes uneven tyre wear.
On front wheel-drive cars, it is especially important to rotate your tyres periodically because the front tyres wear faster than the rear tyres. Uneven tyre profile depth, front to rear, will give you uneven braking and poor handling, especially in the rain. If you don't rotate the tyres, you'll wind up replacing them two at the time, which means you'll always have uneven tread thickness. Replacing tyres in a matched set of four will keep the handling and braking traction of the car balanced.
Pay attention if you have directional tyres. Directional tyres would remain on the same side of the vehicle and be rotated straight forward and straight back to avoid the tyre to rotate in the wrong direction. To be sure if your tyres are directional please check the tyre sidewall for an arrow with the word "rotation" on the sidewall.
Also, some vehicles may have different sized tyres or axle specific tread designs mounted on the front and rear axles, and these tyres may have rotation restrictions.
