275-60R-15 on 8" LBP wheels and 4.250" BS. That is mounted on a 73 A-body 8 1/4 rear end.
No spacers and no clearance issues.

That makes sense to me.
LBP 8 1/4 is tiny bit wider that SBP 8 3/4. And the 4.25 backspace pushes the tire outward a little too. Most 15x8 rims are 4.50" backspace
Think you've got that backward. LBP 8.25 is ~56.75" drum to drum, even the SBP 8 3/4 is 57.125".
Still makes sense though, you'd need the 4.5" (or more) backspace on the 15x8 with the 8 3/4 to put the tire in the same place as the 8.25 with a 15x8 and 4.25" backspace.

My bad. I thought the LBP 8 1/4 was wider.
I ran 245/60/15 on a 15x7 4.25 backspace and thought it was sorta tight on the inside. But the 8" rim must pull the 275 to the outside enough for inside clearance.
