I have tubeless road wheels and like most who try them i`m convinced of the benefits.
Question is, i previously ran Challenge open tubulars for the feel etc and given the fairly unique construction i wonder if they would go up and be stable as tubeless tyres.
Anyone have any experience or just opinion before i try this weekend?
That's a really bad idea.
Challenge open tubulars are light, flimsy race tyres with stretchy beads.
On the plus side, you'll be unlikely to even get them out of the house/ garage before they blow.
I'm a convert except when installation is a PITA (50% of tries).
They say only use tubeless tyres as the bead stretches on regular tyes. I don't get this because...it doesn't stretch (otherwise the tube would blow the tyre off...)
They can’t even handle CX pressures tubeless so no chance on the road
Given the greater potential for 'life-altering' catastrophe if a ghetto tubeless tyre blows off the rim at 70+kph there's no chance in hell I'd try it..
(otherwise the tube would blow the tyre off…)
Isn't the inner tube pressing the inside of the tyre against the rim part of what holds the tyre on.? I'm sure I've read that one of the advantages of road tubeless is that even in the event of a complete, instant tyre deflation, tubeless is safer as it won't come off the rim due to the 'beefed up' tyre bead and more rigid structure.
No chance of using a delicate open tubular for tubeless.
Ah that makes sense Highlander.
I suppose the tyre needs a grippy bead (rather than non-stretchy).
Hmm, i figured as they are the same as tubs effectively and an utter bas***d to fit they might be ok. Also they arent featherlite, more like built to be supple with a higher thread count.
Has anyone actually used them tubeless?
Not really answering your question so feel free to ignore but the pitfalls to using them ghetto tubeless aren't anything to do with them being 'like' tubulars because they aren't in the vital aspect that tubulars are stitched together and glued to the rim. As soon as you take the glue and the stitching away then you are back to the same issues with them coming off the rim.
I think the accepted wisdom is that even though ghetto tubeless is a thing off-road, the higher pressures and speeds involved on road makes it just not worth the risk.
ok, thanks. I will keep them for the spare bike then.
Seems a shame to have such lovely kit hanging around.
