I will soon be taking delivery of a MX 100D and already have an extra set of 19 inch wheels for my Model S which have snow tires on them. Looking at Tesla's Model X specific accessories web pages, I noticed that 19 inch wheels with winter tires are sold (so are 20 inch wheels/tires).
Therefore I called the Salt Lake City service center to ask whether I could use my 19 inch winter MS wheels/tires on my MX. The answer was that it is NOT recommended. The MX wheels/tires are thicker than the MS wheels/tires, even though both are 19 inch diameters. I am posting this in case others are in the same situation.
