I've been all through the archives, at TireRack, other forums, etc. I killed a rear tire this weekend, a front developed a small bubble as a manuf. defect & Dunlop no longer makes the Sport 9000 to replace them. The consensus here seems to be Goodyear Eagle F1 GS-D3. I'm going with the standard 205 55 ZR16 & 225 50 ZR16 I put on about 8K miles per year, I don't track, I live in NJ, I don't drive in the snow and try & avoid the rain (windshield use to leak) Sounds reasonable?
