I've never heard of blowing wheels from over pressure, in the RV world. It's a big no-no in the commercial hauling world, but they over loaded them which is the real problem.
Most of the 6 lug alum wheels are rated for 80 psi. I would not worry about more pressure, but I definitely would NOT load them heavier than the rating. So the question becomes, why run 100 psi? It isn't needed at the load for which the wheels are rated. Your tires will handle that load at the original tire pressure rating.
I would not run 100 psi on a 65 psi rated wheel.
