I am finishing up my M1114 build and have been going back and forth on wheel choices. Some back of the napkin, real rough numbers I used for looking at the bearing loading with higher offset wheels:
Unarmored hub load/Max GVW hub load 1750lb/3750lb (@50/50 which i know isnt striclty true). From my measurements it looks like the tire centerline on a stock wheel lines up with the outer spindle bearing certerline, give or take.
Using simple class 2 lever Calc for outer bearing: +12mm, 0mm, -18mm offset yields +40٪, +50٪ and +69٪ outer bearing loading WRT stock offset. The -18mm wheel total load looks to be less than a fully armored and loaded truck on a stock offset wheel by about 800lb. There are still other issues IE deflection, possible seal issues, inner bearing loading, larger scrub radius etc. Thoughts?
I would like to see more pics of ~0 offset wheels.
Also, Thumper it has been my experience that unlike passenger cars where the camber increases and the track width decreases with bump the hmmwv suspention track width looks to widen on bump. I havent profiled the curve, it's based on observation and control arm angle for what it's worth.
