1970 Duster wheels

We're doing a disk brake conversion on my son's car and that means going to large bolt pattern wheels. I have a set of 4 15x6.5" steelies.

I want to purchase a 15x8", 4.5 back space steely for the back and run 275.60 15.

For the front I would like to use 2 of the 15x6.5" and run a 235.60 15.

I'm wanting to know if the 235.60 15 will cause any problems with rubbing. We do have a sway bar on the car.

Thanks
