For those who switch from 20" staggered (315/35 in the rear and 275/40 in the front) to 18" stock in the winter, does the X5 look funny with the extended wheel arches on it? Debating whether or not I will need the extended wheel arches to protect the sides of the X5, or if it will look funny with the factory arches that come with the X5 with 18's, since the tires will most likely stick out about an inch from the body. Won't know what it looks like aesthetically, until I put the 20's on in the spring.

Thanks
