1973 Duster front tires rub

A 15x7” with BBP disks needs about 4.25” of backspace to clear that tire. Even then, a 215/65/15” is 26” tall which is pretty much the upper limit for height in the front for a tire that width. Obviously there’s a little give and take considering the body tolerances on these cars.

Ride height may help the clearance some but raising the car will change your alignment and hurt handling.

Better to get wheels that fit to start with.
