Anyone know if 245/45/17 front and 275/40/17 rear will fit without rubbing?

275 40 will fit in the rear but it depends on the backspacing.

I'll confirm the above. It depends on backspacing and spring rate. I have 275/30-18's on 993 technology twists in the rear and they rub a bit on the front inside with a big load in the trunk. I blame soft torsionbars. I haven't had any rub while autocrossing with an empety trunk.

When I mounted 275/40/17's on the rear of my 86T I had some rubbing on the outside shoulder of the tires. I had to roll the fenders slightly - no more rubbing.
