How are you attaching the treads? We haven't lost a tread since we started screwing them on (though there were a few other less-implementable solutions). We do wear them down eventually--but usually when we do something like loose a steering sensor or otherwise accidentally drag a wheel while it's out of alignment. We just switched our treads on the 2011 bot, and one of them was still alright (the others had been abused as above).

I guess I wouldn't be surprised if the 8" plactions were noticeably less tough than aluminum wheels, though I don't know if there's a difference between the AM and IFI versions. I'm surprised anyone has trouble with the 6", though, and we've put our 4" through so much I don't know what on the FRC level could take them out. Bumps, barriers, dropping off bridges, tipping back onto its wheels, I think we dropped the 2011 one off the cart once...
