295/50-15's

I ran them on my 67 Dart GT.
295/50/15 BF Goodrich radial T/A's, had a lot of sidewall bulge.

Offset kit, no minnie tub, narrowed 8 3/4, rolled lips, 8" rim with 3.75" back space.
Had 1/2" clearance at the springs and a slight rub on the driver side quarter on turns.
Went to Nitto, 275/50/15's drag radial with the same tread width and flatter sidewall. No issues and theirs still the same amount of tire on the ground.
The Nitto's are way stickier though. I really like them.
