[S.P.A.M.er 17]

I always think of 86's bot from 2010 when I hear pneumatic wheels. Here's a video that shows them traversing the bump a couple of times.

Unfortunately I can't comment on them directly since none of my teams have used them.

Having a drop-down ramp was a popular way of getting across the bump in 2012.

180 did this in 2012 with 6"/4" (I forget) wheels. We had no problems crossing the beam with this method.
