Asymmetrical vs.
Directional Tires
Porsche sports car owners are used to the fact that they cannot rotate tires. Having different sized tires in the front and rear combined with directional tires eliminates the possibility of tire rotation.
The asymmetrical tires, rather than showing rotational direction, are marked for inside and outside mounting on the rim. The outside of the tread pattern always has the handling blocks. With a slight difference in tread design it almost looks like one tire is on backwards. These tires, however, do allow for rotation from side to side. Flipping them still results in the outside staying on the outside.
An interesting tip, is not only can they be rotated; they should be rotated to enhance tire life. As the tires break-in, they tend to develop their own wear pattern. If the direction of the rotation can be changed irregular and pattern wear can be eliminated. This will also aid in keeping Ultra High Performance tires quieter.
By swapping sides at 1,000 miles and every 3- 4,000 miles thereafter, the wear will be more even and give you a few more miles before replacement. This also assists with the more powerful cars wearing the right rear quicker than the other tires.
