I just purchased a E350 4matic and I have this size X-ice2 snow tires that are one season old from my old car. The diameter of the tire is 27.2 and from what I can see the stock tires have a 25.7" dia. From looking at the car,with a total dia increase of 1.6" the difference gives me about 0.8" difference in height. It looks like the hight is not going to be an issue and from what I can see, there seems to be sufficient clearance inside the wheel wells but I am wondering about turning. Anyone have an experience with this dia tire perhaps on a 19 or 20" rim?
