widest tire

I've run some 265/50 15 BFG's on 15x10 Centerline Drag lights w/5 inch offset on my '72 Duster 340. They were less than a 1/4 inch from the SS springs and rubbed a little bit on the spring during hard cornering.

Now I'm running 255/60 15 M/T ET streets on the same rims, but, had to use a 1/4 inch aluminum spacer to get a little more clearance for the springs.

I've heard of people saying that they've run 275's on their Duster. I never tried any tires that wide because the 265 BFG's were so close to the springs that I couldn't get a finger tip between the tires and the SS springs.
