Still got the label "TR 011" tubeless, bought 3 or 4 months ago from a well known reputable trials dealer, I thought i may be able to sell it on but couldn't in all honesty not tell prospective purchaser, so waiting for someone who runs a tube?
Oh, and i ran it at 4psi, maybe they need more? Just dont want the hassle of trying again with tape on the rims and failing. Be interested if you buy one at what pressure the bead pops, it was just so easy to fit, didn't need tyre irons to fit just used hands and heel of foot.
