68 Barracuda Notch 15x7 Wheel Question

They originally were 4 1/4" So double check and measure with straight edge to very edge rim to the mounting bolt surface.

I have run them with 225/60/15 tires front and rear with large bolt pattern. But that is very close in front. People have had that rub backing up with thier 67-69 Cudas.

Now the small bolt front end is supposed to be narrower by 1/4"? on each side.

215/60/15 would a safer bet in the front for tire clearance.
