It's not the tires! :chairshot: Lexus has designed the sc 430 with negative camber so that the inner tread wears out. No matter what. I rotated the tires x 3 and had 2 alignments done. I had to get rid of the Dunlop OEM run flats after 17,500 miles. I am told that that O gpt very good mileage but considering that the other 4 treads on each of the tires had approx. 8k miles left, the way I see it is that the alignment design wastes 4/5 of the tire! Anyone out there have a comment?? I know about the bushing replacements kits etc. That really is not the issue. For a $64K+ car to run like crap after only 17,000 miles is not right. Anyone pursue this with Lexus? Did you get any joy???
