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.

I think it is more of a time issue with those HF tires. The sidewalls will begin to fall apart and the rubber seems to break down after 1-2 years. When they finally let go, it is a fantastically loud noise. Two years ago we were airing up our robot carts tires and one let loose while I was sitting next to it filling it. I am by no means nimble anymore, but without knowing how or why, I was standing up before the room stopped echoing. That was at about 30 psi. We have since decided to run solid wheels and start moving away from HF wheels and tires.
They had a well made scouting form on the bottom was a check box with nothing next to it, when asked what the box was for they said.
