Wheel and tire question for 68 GTS

I have 215s all the way around on mine. 15x7 in the rear and 15x6 in the front. 235s will fit with the correct offset.

Thanks for the response dart4. The reason I was asking about the two tire sizes was the back is slightly raised. If it was level I would probably go with the same size. The offset for the 15x7 sbp wheels is 4 inches. You have no clearance issues with the 215's in the front? Does your car have the nose piece? Here's a picture, albeit a bad one.
