i just posted my pics up today of the 20x10+35 with 275/40's.it's close with that offset i wouldn't want to go any larger on the front. on the back a 305 would have been nice.
that being said give the 305's a shot.
305's are around double what a 275 costs.
what are you looking for summer or all season?
