Tire Wear Photo - Need Advice
Front tires have both worn quickly on inside corners (cupped). One in photo above is down to cords in one place. Wear is more severe in some places (not even all the way around) Car is 1997 with 62K and driven very seldom and with great care. Tires are 225/40 ZR18 (92W) Toyo Proxes T1S mounted on ADR GT Sports, 18 x 7.5, 5x114.3 with offset of either 42 or 48 (info from ADR - these were on car when purchased.) I inflate fronts to 40 psi cold and rears to 36. Rears are wearing evenly. I understand that cupping is usually associated with negative camber. Before I replace the fronts, I need some advice on what to do to correct the problem. Will an alignment take care of it? Anything wrong with tire/wheel size? Anyone have similar issues? Thanks for your help ...

Re: Tire Wear Photo - Need Advice
Allignment should do it, but you'll want to have your components checked also. The top of the wheel is tilted too far inboard.

Check the toe, but with it localized in such a small severe strip have them check the front control arm bushings to make sure they aren't dead.

Re: Tire Wear Photo - Need Advice
Two guesses.
1. Defective tires. I've seen it before, we had a Saab come into the shop with all 4 tires worn like that. That batch of tires had been screwed up and the steel belts were too small, allowing excessive flex of the shoulder. We put the car on the alignement rack to check and everything was bang on spec. 2. Check to see if the tire is touching the lower spring perch (the strut). If that's the case you either have too much camber, or something is broken/bent. You're running standard width wheels and tires, with less offset (the wheel is pushed farther out), so that can't be the culprit.

Three words for you: General Exclaim UHP. Well, two words and an acronym. 400 treadwear rating. I've had mine on for ~6000 miles and they look brand new, still have some of the little nubs left.

Re: Tire Wear Photo - Need Advice
Looks like the way every set of yokohamas I've had on an svx wore out. Always thought it was my suspension/alignment until I switched brands.

Re: Tire Wear Photo - Need Advice
Looks to me like very low tire pressures.
