I'm looking for some extreme summer performance tires to replace my Goodyear run-flats. I don't see many options on the Tire Rack site. Potenza RE 71 and Advan AD 08R.

Any other options out there?
Can we safely change the tire size up or down to increase our selection?

How about any tiers the Tire Rack doesn't sell?

The intended use is primarily Autocross used and Sunny Sunday Driving, not a daily driver

RE-11's have a 225/45 that has a 25.9 diameter. The 265/40 has a diameter of 26.3". Is this an acceptable discrepancy in diameter from front to rear?
