i've got a 91 ls, 15x7 stern agguzies 43mm backspacing, i've got 205/50/15's on right now, but i want to go wider, would a 225/50/15 rub? i've got about a 2 finger wheel gap (1"-1 1/2") how about 215/45/15's? does any company make good 215/50/15's?

 

why do you want wider? i think 205's are fine. i've seen a 215/50-15 size before, but i think it was only H rated, not a high performance tire.
