I've got 275/50's mounted on my Vectors(8.5") and they fit/look great...I also have my BFG street tires(235/60) mounted on stock T rims....I'd think the 235/60 would look a lil odd on 8" wide rims, IMO :smile:
I have 8.5 rims on the back with a 4 inch backspace and I'm running a 295/50 with no rubbing issues. It's close to the frame, about 3/8 of an inch, but no rubs.
I run 255 60 15 M/T drag radial's on my stock 7" T wheels & they look, fit & perform well. The 27" height of the 255 60 seems to be a little better rpm match than the 235 tire also.
