Wheel and rim sizes.

My friend is looking to put 245-60-15 tires on 8 inch rims with a 3&1/2 inch back space on his 74 Barracuda. I know the tires are not a problem because my son has 255-60-15 on his Barracuda but has 7 inch rims. I was wondering if the rims would fit without rubbing the outer wheel wells.Thanks.

I have 15x8s on the back of my Cuda, but the backspacing is 4.5 inches. Don't know for sure, but would guess that 15x8s with 3.5 inch backspacing would rub since the wheels would be an inch further out.

I have 275s on the rear with 8” rims.

This picture might help understand backspacing and offset. Mopars want close to zero offset.

I understand how backspacing works. I was not sure if the Barracuda would have enough room to fit an 8 inch rim with 3&1/2 inch backspacing.

No, it will not fit with a 15x8 with only a 3-1/2" back spacing. I run 295/50/15's with 15x8 with a 4-1/4" to 4-1/2" on 6 different wheels and tires sets on my cars.
