There's lots of good 15" tires. Grassroots Motorsports magazine just had another comparison. They are 200 treadwear but last forever in these cars. 205's are usually the narrowest though. As other have said, clearance on the front when turned may be an issue. I had clearance my foot well by 1/2". If you don't need the clearance for brakes, 13's are easier and there's a few decent performance tires, R888R, AR-1.
