My S eats up my rear tires from inside to out is that normal i though they would waste evenly

chansta

inside to out meaning the center of the tire right?

check ur tire pressure... might be too high.

It's completely normal. The S isn't your parents' sedan.

Start here:

and then search around for camber.

Did you or a previous owner (assuming yours is used) have a negative camber set up? That'll eat through tires faster than a zero camber set up, but it won't handle as well if you like pushing the car into the corners.

Also, what tires are you using? I have Goodyear Eagle F1's, GS-D3 and they wear out quick, 15-20k mi. I'm thinking of finding some other tires for it because of the wear issue but the problem is I don't want to lose the grip but with what these tires cost, even from Tire Rack, I think I'm going to have to bite the bullet and go with something else.

stagger tires will wear out from the in to out .

Get an alignment. Excessive toe will cause increased wear.

Also, as stated, if it is wearing in the middle of the tire, you're likely over-inflating the tires. Something around 32psi cold pressure is usually a good place to start.

HAte to tell ya mxt_77 but toe dont wear tires.

TookayS2K

you are wrong.

CKit

Normal if you have a lot of straight-line driving.

lol wut?

Toe will wear tires much faster than camber will.

Think of it... if you have non-zero toe, then you're effectively "dragging" the tire sideways as you drive (since it's pointing in a different direction than the direction of travel). However, if you have zero toe, but non-zero camber, then the tire is still spinning/turning in the correct direction; however, you're just putting more weight on a smaller portion of the tire.
