Knowing that a custom wheel company is local to us, it would be nearly criminal not to bring our new BMW M4 over and try on a series of different wheels and tires to find out the maximum we could run – especially in the rear. At CCW (Complete Custom Wheels) here in Central Florida, our goal was to find out how far we could push the sizes and fitments without any rubbing or having to roll the fenders.
After several combinations were installed, including a few pairs of wheels off the shelf, we were able to fit a 19″ x 11.5″ 325/30/19 in the rear. We also compressed the rear to simulate fitment with coil overs. This helps to produce the best sizes for each customer’s unique preference and use of the car (street/track).
