I’m looking to put some new wheels on my car. 2010 c300 4matic. I had 20s on there with 8.5 all the way around and experienced some rubbing in the rear that I did t like. I’m looking at 18x8 or 19x8 now. Any recommendations on which would be best and what tire size is recommended. My factory wheels are staggered 17s. 17x8.5 rear and 17x7.5 front.
