Default Replaced stock tires after 15,000 miles with Goodyear Eagle F1's

Replaced the original Bridgestone Potenza RE050 after 15,000 miles with Goodyear Eagle F1 All seasons. I went with these over the GS D3 more for longer tread life as well as better price, 420 vs. 240 UTOG, and about $200less. I paid 892.00 with tire protection. These tires have very good reviews on Tire Rack and some car mags. They feel much better than the stock tires in the corners, ride comfort is better{less jarring**, and noise is about the same.


I also had a 4 wheel alignment, and the tech said the there is no camber adjustment on this car. Does that sound right? I have had too much inside wear on all 4 tires, {too much negative camber**, which is the factory spec for the sport suspension.** Are there any TSB's for too much inside wear/negative camber?

I will post pics ASAP.

The rear rims are wider.

225 in the front and 255 in the rear.

Totally unrelated, but does anyone know if putting the rear 18's on the front causes rubbing?

Assume no drop, OEM tires.

This question has been asked about 1,000,000,000 times, and I wish someone would take 30 minutes to swap their fronts and rears to put this rest...

If no one has done it when I'm ready to swap out my tires, I promise I will.

or maybe just some weekend that I get bored...

^^ It has been tried before - Al503 posted that the rears rubbed on his IS350, not sure about a IS250, but the +50 offset & 255s won't work on the front of a IS350 . . .
