The wheels are not interchangeable between the RWD and X drivetrains. Each car specified different "Offsets" for the wheels, which is the relationship between the wheel rim and the wheel center, and defines just how far in or out the rim is placed relative to the axle hub. In essence, the axles on the two cars are different lengths, within the same body, so the wheels are designed to accomodate that difference and look to be in the same place on both. You can find the offset specs for different wheel sizes on your specific vehicle on RealOEM.com, etc. The offset is stamped into the back side of all wheels, once you know how to read the codes. You will find that the X cars have far fewer choices among commonly available wheel styles, but the wrong offsets just won't work.
