I run 275/60/15 MT Street ST's on 15 x 7 steelies, w/4.25 BS, 1/2" spacer to keep the tires away from the SS springs.

7 inch wheels put the tire closer to the spring because of tire bulge . 3 1/2 BS with 7 inch wheels 4 1/4 with 8 inch. I have a 8"set on my Duster with 275's Small bold pattern.

Large bolt pattern is 4 1/2 or 4 /3/4 if you can find them and use a 1/8 spacer. Orange car is Big Bolt.
