need more tire somehow

Fwiw on the back of my 67 Barracuda, stock 8 3/4, I had 15x7 4.5bs 255/60s.

Passenger side was a bit closer to the spring, typical for Mopars imo.
Once I put on a rear swaybar it caused a bit of tire rub on that side.

Now have bbp axles with 15x8 4.5bs 275/60s.
Same distance from springs as before but no rub on passenger side.
