Having issues with pinch-flats on the hack. Anyone tried to run 700c touring tyres tubeless (with eg. a NoTubes rim strip & sealant)? If so, what tyres, and how well did it work?
Andy
Only used proper tubeless tyres - what pressures are you running?
6 Bar rings a bell; I appreciate this would be a bit much for tubeless. Problem is that I don't think anyone makes proper tubeless 700x35c slicks...
I think you are right. Flats at 90psi on a 700 x 35 seems odd though, you doing a lot of rough paths?
No - it's a bit odd. Got home from a 15 mile round trip (on what passes for smooth tarmac in Pennine Lancashire), sat down in kitchen & heard loud & ominous hissing from garage. I suspect this is due to cack-handed tube installation as much as anything else (run the MTB tubeless) but haven't had a chance to take the tyre off to investigate. No obvious surface damage though.
Wondering whether I might be able to solve the problem by not having tubes.
v. unlikely to be a pinch flat.
you need proper tubeless tyres for road work, and the Hutchinson Intensive in 25mm is the widest that I know of.
Having said that, I ran a regular 28mm Conti GP4Season as tubeless (ghetto) for a few days but the sidewalls were leaky, even with loads of sealant.
Just check your rimtape and current tyres for flints/debris. Decent tyres are pretty bullet proof - I've not had a puncture on my 28mm GP4s on my commuter for well over two years.
v. unlikely to be a pinch flat.
No. Hole by the valve, on the rim side. This is about the third tube I've had go there. At a loss to explain this one. Only possibility I can think of is that it's a spoke head peeping through (it's a sh!tty single wall rim) since I changed the old perished rubber rim strip for a fabric Ritchey one, but the hole doesn't seem to be near any of the spoke heads.
If it does it again, I'm off down the LBS to see about re-rimming the wheel.

If you're getting punctures rim side, its nothing to with the tyre, its the rimtape/rim
Get some velox rim cloth, and check the rim for burrs
