I was just wondering where you put the tires when you rotate them? Front to back or in an X pattern. I had 2000 miles on the F1s when I put the winter tires on and now its time for the F1s to go back on. Thanks!

The F1's can rotate either direction but they do have an inside and outside (ie: must be mounted properly). GS-D3's can rotate only one way. I have PS2's that can rotate either way, like the F1's, so when rotating I use the X pattern, but front to back works too. GS-D3's must use front to back.

The owners manuals usually indicate a Modified X rotational pattern.
That is what I use because it ensures the tires see each corner of the car.

Move the drive wheels straight to the other axle, left rear to left front and right rear to right front.
Then cross the fronts to the back. Left front to right rear and right front to left rear.
Don't forget to reprogram the TPM!

I can only swap my PS2s side to side...:bouncy:

I have staggered size uni-directional tires. I can't rotate at all :(

Ohh well.

I have always rotated front to rear, never side to side. If aligned properly, your left and right tires should get equal wear, so it doesn't matter which side it's on. I was told years ago that once a tire gets broken in, the steel belts can be damaged by reversing the direction of rotation (side to side rotation).

Who knows if there's any truth to it, but I've never had a blistered sidewall from tread seperation so I suppose it's been good advice so far.

I hope you meant front-to-back. Directional tires cannot be swapped side-to-side since that would cause them to rotate in the wrong direction.
PS2s are asymmetrical but not uni-directional. The fronts are 245/45 on 18x8.5" stockers with the rears being 275/40 on 18x9.25" almost stockers...

The driver's side tire can wear a little more quickly unless you always have a passenger. Or unless you have the stature of Calista Flockhart, Tony...**cough**burp**fart**

Plus, many people tend to drive a little harder in one direction over the other. Most V members who watch their g-meter closely will notice one side is usually higher than the other.

My personal bad habit is that I peel out in the V much more often turning left than turning right. My RR tire usually wears more quickly than my LR.
