The Boxster uses Directional Tires. Directional Tires are designed to improve wet-road traction and have an asymmetrically designed tread to provide more rubber contact on the outer edge of the Tire with the road.

Directional, high performance tires are mounted with the arrow on the top of the sidewall pointing in the direction of travel. When these tires are rotated, it is important that they remain on the proper side of the vehicle. Since the Boxster uses a different size Tire Front/Rear, they cannot be rotated. Hope this helps...

thanx - now can you come out to soCal and figure out why my car is shaking?!!!!!!

Some people actually rotate directional tires by dismounting them and remounting them on the other wheel. Kind of not very cost-effective on a tire that wears down as fast as these do though, eh?

It's also been noted that the "directional" part of directional tires really just refers to how the tread responds in the wet, and how quiet the tires are. I've known a lot of racers that rotate their directional race tires--they're running enough camber/toe to get the inside edge to wear out rather fast, plus their running shaved R-compounds where hell, the tread is just slowing you down.

But, that's a very specific application and you didn't hear it from me!

Hi,

You're correct, once you absorb the cost of Mounting and Balancing, there's not a great deal of Cost/Benefit to mounting the Tires on the other wheels. Better to save the cost and apply it to the next set of Tires...
