We're having pretty great success with them, too. Kept the split rim, just knocked the bearings out and pressed a hex-broached aluminum plug into place. Nice and cost effective, and so far it's been eating defenses alive.

We didn't have any trouble with the metal, tread, or sidewalls, but we were losing inner tubes at a rate of a couple a month. All of the failures I looked at were at the seams, most commonly near the base of the filler tube. While our air cannon is a bit heavier than an FRC-legal robot (closer to 200# on 6 wheels), we never ran it at high speed or over any obstacles bigger than about a 1" transition at the edge of a sidewalk. All the ones I saw were seeping leaks, so we weren't aware of exactly when the damage occurred.
Especially with the brutal defenses of Stronghold you may be better off if you upgrade your inner tubes. At the very least have spares on hand and a procedure to swap them out.
