Rotating tires

[MikeTZ]

Mike, May I ask where you got this done? I live down in Southern Pines and I'm having a hard time finding a tire shop that I feel comfortable dealing with.
Thanks,
MikeT

I disagree.

My Michelin PS2 tyres indicate that one side faces the outside and 1 faces the inside. If this is true then if I switched the rims, it would make no difference since the same side of the tyre must face the same direction. Outside must face outward no matter what side of the car its on.

If I turned the tire the opposite way, (rotating them), then, while it would wear even, it is against the way Michelin designed them to operate. I am sure they have different compunds on different sides of the tread, as well as different sidewall strengths as well which would be crucial for correct handling.

As a street driver I have never rotated my tyres (on my 987). I always just replace them. They wear slightly inside but not too far from equal. You may need a good alignment.

Other people have done this it seems so correct me if needed. I would guess I have directional tyres and they might not all be the same.

PS2s are not directional, so you're stuck. All you can do is move them side to side on the car, but that won't help wear. Directional tires such as the Bridgestone Potenza S-O2A that the OP has don't have an "outside" wall and can be flipped on the wheel.

Most boxsters dont have an LSD so would you not get some more wear distribution by swapping sides....? I don't think that they (ps2s) are directional....the drive wheel may see more wear

I tend to chirp it even with traction control on

If you chirp the tires every time you start, then I suppose you're right.

But you have to do some serious intraspection and ask yourself, "Why do I feel the need to do this every time?"

I was going to say that you'll replace your clutch more often than others too then. But, you probably don't care about that. I drive pretty hard and never "chirp" the tires - without traction control.

...no not everytime but once in a while and its the drive wheel that probably gets it....so it might wear more

...just pulled the clutch and it was no different than new and put it back in

It's not just with standing starts, the R. Rear tends to spin in 1st ( sometimes 2nd ) gear corners, while turning right.
