235/60/15 on front of duster?

Your 15x7 with 4.5 bs is MUCH easier to fit than 15x8 with 4"bs. MUCH! I would go with the coopers, cause I like them much better than the bfg's (letters stay white, for one thing), and I would use the 225s, simply because they work better on a 7" rim. I have used 235/60x15 9n a six inch rim, on a b-body..... but it wasn't right.
