I have them on my jump bike, I'm pretty sure it was from riding home as I don't remember pinching them at the skate park.
I'm looking at options to run them on my trials bike, which will be more street than pure trials. I don't want to put max PSI in and was looking at a thicker tube, inserts or trying to run them tubeless.
I can just about get the 2.25 in there as I have an inner tube wrapped round the chainstay. I've test fitted the wheel from the jump bike.
