I have 02 996 with P Zero Rosso. Do we ever need to rotate those tires (changing left to right?)

it is pain to rotate a staggered set up car. plus our tires are direction tire which mean you have to unmount it and remount/balance for rotate, that will cost around 80 bucks... no..I wouldn't bother with rotate...

I thought the roso are asimmetrico not directional, so they can be run on both direction. Am I right?

I use Conti SC2's which are non-directional so they can be rotated left-to-right and vice-versa. And yes, the tires should be rotated.

It doesn't matter whether they are directional or not. The fasted way to destroy a tire is to change the direction from the original rotation. The tires would have to be removed and remounted to do so which would cost more hassle and money than anything you would gain on tire life increase.

I agree with this message...

I was going to do this on my fronts as i was getting wear on the outside shoulders (probably from my bad driving in AX). Unmount, rotate sides, re-miount and balance.
The tire installer wouldnt do it as they said it would screw up the handling on a hi performance car.
Is this true ?

if you get uneven wear, have alignment checked.

you do not need to rotate if the tires are directional. if asymetrical, you can but i am not sure if it's worth it. typically L and R tires are worn pretty evenly for me.

What about the Pilot Sport Cups? Aren't they marked inside/outside rather than directional? If you swap from left to right is that a problem???

I rotated and rotated/swapped sides for my Contis (inside/outside marked)
Now they seem to drive better, less shimmer on steering.

it's also something to think about that those of us with turbo twist variants, etc. have to mount/dismount the tires or they'll be facing the wrong way!

I thought about that before...
Aren't the wheel designs exactly the same for all 4 wheels,
that the spokes are angled in the opposite directions when mounted on opposite sides of the car? Like on one side, the spokes will be "slicing" into the rotation, the other side against? I asked that question before and heard it doesn't make a difference at all, and the wheels can be used at any side of the car.

Back in the day when I did lots of track driving, I had my car setup with massive negative camber to offset the excessive wear on the outside edge of the tire. It was well worth the trouble, and the car actually handles better since more of the tire is on the pavement when cornering. AX is a different story, but if you're doing it enough and hard enough to make a visible difference on your tires, then I'd say try that.

I am against rotating tires at all because it does change the handling characteristics of the car. And it will also mask other problems that you might have, that are more readily visible when the same tire is in the same spot all the time.

Just my .02

Michael,
I have the alignment set up by a good local shop.
The max negative camber on the fronts was -0.8-degrees and they set mine to -0.7-degrees. I'll have to see if this helps. Normally i hear people wear out the inside shoulders due to the camber settings... perhaps i drive like a maniac ?
Im installing new tires on thursday all around, so i'll see how these wear with the new alignment from new.

BTW: The rear toe was WAY off ... and had always been this was since new. I was getting even wear but only 4000-5000 miles on a set of rears... they travelled as much sideways as forwards :-)

Hey Karl,

I hope the new tires and alignment solve all of your ills. Tell me guys, my understanding when I had my 993 was that only a Porsche shop had the proper gizmos to properly determine and set the rear alignment on those cars. Does this still hold true with the 996, or can any decent shop with a late-model alignment machine do it?

Thanks,

Michael
