If it does, then have Bombardier-Alstom reduce the profiles of the wheels shipped. Maybe Alstom uses the same manufacturer for the wheels for the MK V as they use for their other trains. It may be standard gauge but maybe didn't take into account the difference in vehicle weight
Or innovate and make the trains have an dynamically adjustable suspension. Like there are cars out there that have this as a feature. It should not be an unreasonable ask to to have 2" of adjustable suspension give to compensate for wheel wear.
For all I know, maybe they can do this without doing anything at all, maybe there are adjustment features on the train and we just aren't privy to that.

There might be some tolerance in the suspension as well, although the LIM requires pretty close adjustment. I'm not sure how much springs like that would soften as they get worn in. There would be a little bit of fatigue as they break in.
