33 on the front imo is silly, i did 29 for about 6 months on my t1-s' and they went bold in the center and hardly touched the outside treds... meaning they were way to high at 29! you guys that have them up above 30psi want to try knocking them down just for a while and you'll soon find they're better at lower psi's...
people use these tyres all the time on the lotus elise's, and they run them from 16psi to 26psi most of the time, not heard of anyone running them higher on them either...
