I have 315's for the rear tires now will a 325 or 345 fit

My best friend ran 335's on 17x11 TT2's for a couple of years. Just a little fender massaging. Not that bad.

What keeps the car from falling off that 90 degree lift in the center pic. That would be great for detailing the undercarriage.;)

i wanted to put a 325 wide tire on mine but as you can see in my sig, with the wrong backspacing im stuck with these 275's. i want to look like that red car. but with a mini-tub and the tires in the fender good.
