My 997 needs new tires in rear. The inside shoulder was badly worn on both. My question, is this a common problem? I was told by some that I wasn't driving aggressively enough for even tire wear. How common is it for camber to be off on a 997? Is it expensive or difficult to do? Thanks

 

Funny I have the opposite problem. But as you noted you're either driving only in straight lines or not turning hard enough.

 

It is very common for camber to be off in a modern Porsche simply because the car needs an alignment but hasn't been given one, a proper one.

But even if the camber is out, my experience after nearly 260K miles in my Boxster, and nearly 90K miles in my Turbo, is camber is not the cause of the tire wear you describe. The rear tire wear you describe comes not from camber but from incorrect toe.

Get new tires fitted.

But before you go get new tires fitted, fill up the gas tank. Remove dead weight from the car. Be sure the toolkit and spare tire though I think your model of car doesn't have one are secure in their proper location.

Then after the new tires are fitted treat the car to a proper 4 wheel alignment.

Then, experience considerably more service life from the rear tires.

Worst case is I've had to replace the Turbo's rear tires after 8K miles. While I had the car aligned unbeknownst to me it was a bad job. This last set of rear tires though lasted just over 23K miles, then I had to replace both rear tires.

Not because they were worn out -- tire tread depth was 3mm -- but because one tire had a bad puncture.

Sincerely,

Macster.
