It's the suspension on our cars, more specifically the camber of the tires. There is a very good thread on this here: https://www.clublexus.com/forums/sc-...t-in-spec.html Take a few minutes and read the thread and a link I posted.

Oh, BTW welcome to the forum.

I heard about this issue with our cars just before I bought mine CPO in 2008. As part of the deal with the Lexus dealer, I asked them to change my camber settings to as neutral as they could get it. I agreed to sacrifice a little bit of handling so I could use my tires longer. I have run 17,000 miles on new Pirelli P Zero Nero RFTs and there is a lot of life left in the tires without any evidence of uneven wear on the insides. And I don't think my car's handling is that bad as a result.

Another Lexus dealer who was working on my car commented that my tires were in pretty good shape for an SC430. So I am pretty happy with the camber setting changes.

Thanks for the imput... I now plan on adjusting my camber to neutral. I can live with 15k... But 5k is nutz

No need to go to neutral. I doubt that you can get there anyway. Mine is set to about -1degree and I have about 15K miles on new tires with no uneven wear. Before the new tires and original alignment the inside wore very badly.

Don't go "neutral". It can be unsafe because you're not allowing much compliance around the turn. You can end up having less contact patch.

Camber is not the source of problem unless you're above -2.0-2.5 degrees. Anything less than that, you need to look elsewhere. If your camber is within an acceptable range, then your toe is usually the problem. People usually mistaken for the fact that camber is the ultimate source of inner tire wear. Having slightly negative camber is not an issue. However having incorrect toe will wear your tires MUCH faster.

Once you pay the $170, it's free whenever you want to get an alignment? No taxes, labor, etc..? How good is the service? I paid $90 for a one time alignment, I'm thinking firestone may be the best route.

Yes, it is free at Firestone after the initial payment for the lifetime alignment. Driving in, wait and drive out, no pay to go.

Alignment was cometed by a top notch shop .. I have a printout somewhere its not that... New 20 inch rims must be the issue.. Again thanks for all the advice
