The wheel wells on a leaf spring truck are the problem before the leafs. I have a '69 short step in the driveway now. It has 265 75 15 on the original wheels from my Jimmy. I want to do an axle flip in the back and go with 275 60 15 BFG drag radials. It looks like a 15x8 wheel with 3 1/2" BS would work.

I am probably going to mount the tire on one of my 15x10 Centerline ProTruck wheels as a starting point and see how much clearance I have. Will be interested to see what other responders say.
