I have been spending a fair amount of time on the trainer these days. On the weekends I can get out and my continental grand prix 4000S's are fading fast. Had a flat a few months back and replaced the rear, now the wear indicators are showing it is almost done. At $60 bucks a whack I am reconsidering my need for lightweight "super" tires. Does anyone recommend a good "happy medium" tire for trainer and road without having to change tires every week? I was thinking something in the kevlar area. I also thought about buying a low end wheel and putting a cassette and trainer specific tire on it. What do you guys do?
