I put a set of "Sime tyre" on the Celica just before I sold it, and they were fine for grip, but WAY too soft in the sidewalls. They made the steering feel really vague and doughy after the sweet sweet Goodyear Eagle F1's I had on teh front.
thats cause they have got a 1 ply sidewall
ive got some 215/65/14's on 7" rims for the rolla (just for fun time)
