Now Wholly owned Trek name, Keith Bontrager rolled down 40 hole road rims into smaller Mountain bike rims, home garage frame shop..
to make them Uber light, but the use was on loose soil mountain bikes so the tire slipped on the dirt sideways
as much as it was deformed by the side forces cornering.
My studded tire wheels are the opposite.. Wide Rims, 45mm and A 26x2 tire , or 50mm
The D shaped cross section increases the contact patch to let more of the tire studs down,
to grip better..
