Had a question about tires. My 75 has p245 r15 all the way around. On a hard turn ,either way they rub the rear part of the wheel well. I was thinking about putting p235 s on the front and leaving the rears at 245. I don't want to lay out the cash on a new set of wheels yet (thinking I'll go to 16 or 17 inch wheels in the future) does anyone see a problem with this setup? For the time being.
