I ran those tires on 10 inch rims with 5.0 offset on the back side on my 1971 Duster that had the 8 3/4 one inch narrower than stock. I had the stock outer 1/4 panel wheel wells stretch 5 inches, three to the front and two to the rear. It had ladder bars with coil over rear suspension and full size wheel tubs to the stock inner rear sub frames.
I started off running the larger M/T ET Street Radials 315x60x15 on those same rims and ended up buying the 295 really cheap so I bought them and put the 315 on a set of 12 inch rims with the same zero offset
I raced the car a lot at the track and the smaller tires didn't last as long as the bigger tires did
They worked well, not slower at all
I also ran the same size M/T ET Street bias ply tires,13x31x15 I think, on the street, they worked way better on the street than either set of the radials did
That car was a lot faster than I thought it would be, 10.30s Et at 127 .+ MPH through the exhaust on Oregon pump swill on the radials
