I like the looks of them on the car,I would run it.
when rickster put the 29x15x15 under his truck with the truck axle he used a 10 rim with 7.5 BS.
remember on my truck I have the A-body 8 3/4 and use a 12" wide rim with a 4.5 BS.
I wonder if a 12" wide rim with the 7.5 will fit?
going back to stock springs on mine raised the rear wheelwell a few inches above the tire,so it "could" sick out the fender lip a little with no problems.
