Hi Gang,

I think I'm going to drop my wheel size down from 747 22"s on DHP to 21" 740's on air suspension.

I have a late June build X5m50i on order, and was planning to swap the run-flats on the 21"s to a non-rft when I took delivery.

I just jumped on Tirerack, and there are no 21" non-rft options in that matching front and rear size...

F - 275/40R21
R - 315/35R21

Am I missing something???
