They fail because the bumpers are too damn flimsy!? The bumpers made of C channel were especially bad because the bumper was weak and the welds were also not very strong.? Chalets have 2x4 box beam bumpers and people have been bolting 100 lbs of bikes and bike racks to that and the bumper hasn't been breaking.? Aliner is saving a few dollars on their bumpers and that's why the spares fall off.
If you want to give feedback to Aliner on the ultimate spare mounts tell them to put a spare tire cable winch under the rear of the trailer and mount the spare with that.? Then you have something that will never fail, the spare is less accessible to thieves, the spare won't rot in the sun,? the trailer is about a foot shorter for those with small garages, and then you can fasten other stuff to the rear bumper.
Unfortunately, though, retrofitting a cable winch to an existing trailer is probably not feasible because the floor of the trailer gets in the way of welding it on.

Hi Joe:
They fail due to Torque loading with the addition of shock from road bumps. From an engineer's point of view a sure way to fail.
If they would just secure the top of the spare mount from shaking the shock load wouldn't be a factor.
Our spare is only resting on the bumper and an angle iron of aluminum inside the back wall keeps the tire from falling off.
We all should have a spare, why hasn't Aliner found a standard place to store one, with a jack!
