I know there is a lot of information regarding this topic as I have been researching this for several days. My Mustang with stock suspension needs a new set of tires. My dilemma is I want to run a 255mm tire in front and at least a 285 mm to a 305mm tire for the rear. I would prefer a 19 inch deep dish wheel with modern style multiple spokes in Black or Black chromium color.

I found a set of wheels made by XXR wheels. They are 530D Chromium Black http://www.xxrwheels.com/wheels/xxr-530d

These wheels come in 19x9, 35 mm offset, 6.375 back spacing or 19x9, 20mm offset with 5.75 backspacing and only a 19x10.5., 20mm offset with 6.50 backspacing.

Will the 19x10.5, 20mm offset, 6.5 backspacing with 285mm or 305mm wide tires fit the rear and will I need to widen the fender for clearance?

I would presume I can run the 19x9 35mm offsets in the front. However can I run the 20mm offset, 5.75 back spacing with a 255mm wide tire offset and still clear the whee well.

Any advice will help.
