I looking at a set of 17x8 wheels with a 4.5 backspacing for front and rear. I need to know from a person who has 17x8 with that backspacing and what size tires they are using for the front and rear. I thought using 245/45-17 and I think they would fit the rear fine but am concerned these would rub against the frame during a hard turn in the front. Please provide info. I used to run 15x8 with 225/60-15 with no issues. I believe the 245's are about 1 inch wider. Thanks.
