a lot of variables to consider

my 295-50-15 on a 10" rim looks lost on a 71 B-body

I run 275 60 15 on a 7 inch rim on a 69 bee.

WOW ! And no clearance issues ?

275 60 15 with a 4.5” back space is just the ticket if you want to get away from stock. Carlisle 2018

295/50-15 on 15x10" and 5,5 inch backspace, in the rear of my 1970 RR.
It fits, but barly clears passangerside leafsprings. Big swaybar and HD-leafsprings reduced body roll and rubbing.
