Widest Rear Tire With Factory 12 Bolt? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Not sure if your slightly newer fleetsides are wider or not. I've got eh trailing arm suspension w/ jeep springs which are a tad wider.

If I would have gone with a 7.5" bs, the tire would rub into the outside of the fender.

315/60/15 MT drag radial on 15x10 with 5" bs on stock width 12 bolt. No tubbing needed.

We're running a non tapered, we've alway assumed they were Jeep springs.

And we're running 8.75inches of backspacing.
