Car tires tend to wear out at different rates due to the different weight distribution as well as the additional torque distributed at the drive wheels. The front tires tend to bear the brunt of usage at every turn but also because most cars are front-wheel drive. Rotating the tires ensures that the tires wear out evenly throughout its service life.
According to most car manufacturers, car tires need to be rotated as frequent as lubricant changes. This can take approximately half a year or 12,000 km (7,460 miles). This can vary according to the type of lubricant used too. Some car manufacturers provide a 22,000km (13,670 miles) between oil changes which is too long a duration to wait for a tire rotation. If you drive less than 12,000 km between oil changes then you can rotate the tires every 6 months.
In the case of all-wheel-drive cars where there is a more even wear as compared to a front-wheel or rear-wheel drive vehicles, there will still be some level of uneven wear from the front tires. Most all-wheel-drive car manufacturers recommend a tire rotation every 12,000 km or seven months.
Tyre Rotation Patterns
Directional tires have thread patterns that are designed to run in only one direction. Small arrows on the side of the tire indicate the direction of the roll. For directional tires, tires remain on the side but are switched front and back.
Non-Directional tires on the other hand can be used in both directions. These tires are rotated by moving the rear tires to the front on the same side and crossing the front tires to the back. In other words, the front left tire is moved to the rear right while the front right tire is moved to the rear left.
