I, and many other Lone Stars are running 315's in the rear. I suppose it depends on the length of your rear axle and the offset of your wheels, but going to 325's will only add 10mm, which is about 0.4 inches. I doubt that would be a problem...

My car currently has 315/5016 on the rear now, which are pretty tall. I will be changing wheels and tires to 315/35/17 soon.
