M-101 trailers

[m-11]

Will the wheels and tires on these fit an m-37?

[cuz]

US built M101, M101A1, will if equipped with original wheels and tires. The A2 mounts an 8 lug wheel. The A3 switched to the Hummvee wheel. Also I have seen a lot of guard units that converted from the 900x16 to a conventional 16" tire and wheel on some of the earlier M101 series.

Corrected to match Cabell's description below.

I hate to dissagree...but:

The M101 and M101A1 have the 6.50hx16 Budd wheels that the M37 uses. They also have the same bearings and hubs. They have a mechanically actuated parking brake. The major visible difference between the two is in the style and orientation of the parking brake levers.
The M101A2 have the GM hubs and can mount either a Ford or GM wheel (can't remember the actual size off the top of my head, but the rim bolt pattern is the same with the Ford having a slightly larger hole). They have surge brakes in addition to the mechanical parking brakes. The parking brake levers are the same as those used on the M101A1.
The M101A3 uses the same hub as the HMMWV, otherwise, they are the same as a M101A2.
