Seasonal Tire Change Over
Since many crossover all-wheel-drive vehicles are actually in front-wheel-drive mode most of the time, rotating the tires on these vehicles should be done often, since the front tires can be expected to wear more rapidly than the rear tires.
The rear tires just follow the fronts, so they usually wear more evenly. If you leave tires in place, those outside edges on the front tires will wear down much faster than the rest. A poor alignment or unbalanced tires can also cause uneven wear. Rotating tires keeps them from wearing unevenly.
Tires should be rotated every 10,000 Kms for maximum performance and longevity.
The reason for rotating tires is to equalize wear. Front tires wear a lot faster than rear tires because as you make turns there is more pressure on the outer edges of the front tires. In addition to normal driving, things like three-point turns, parallel parking, U-turns etc. put additional stresses on your front tires that your rear tires don't have to deal with.
