Porous tyres

I have Specialized Fast Track and Renegade tyres fitted on my Epic and have made it tubeless but it leaks. Checked it all over, three times. The Specialized dealer today tells me that they are porous even when tubeless so great, its costing me a small fortune in gas cartridges.

The question is what can you recomend, similar fast rolling tyres that are NOT porous for specialized rims.

    Perhaps a slightly unrelated question: why so many CO2 cartridges? Surely you might need one to seat it the first time and then you'd just inflate with a regular pump when it goes flat?

    Don't have any experience of Spec. tyres, but I've had Maxxis, Kenda and Schwalbe non-tubeless tyres running tubeless on my Stan's rims. All are a little porous (the Kendas were worst), but the right amount of Stan's jizz and a couple of days of shake, wait/ride, reinflate, shake, wait/ride, reinflate has always worked.

    The rear goes completely flat in two days, they might be getting a little better now, so I just use a cartridge, the front I give a few pumps and its good.

    I might try a Furious Fred on the rear as the front is not to bad.

    Surely if the fluid stuff doesn't stop the leaks, it will be pretty useless if there was a real puncture.

    A simple solution is tubes.

  • Never really understood the whole tubeless thing.

    For a few grams extra tubes seem far simpler and a lot less faff.

    I wasn't convinced until I tried it. I must have gone almost 5 years without a puncture with tubes, but then got tubeless-ready wheels and figured I'd give it a go. For me it was a lot less faff than it sounds like. After the first couple of days, when I had to top them up a bit, they were fully sealed and have been ever since. It feels different: a little lighter obviously, and 'suppler' at lower pressures.

    Did he, by any small chance, recommend some of the nice expensive tubeless ready or ust tyres?

    BTW, to fix, more latex milky stuff, more shaking.

    and buy a pump.

    A wise man. I run panaracer xc fire's with the latex & mine never go down. Put some more in and shake away.

    Might be worth preparing the tyres by painting on several layers of dilute latex (or whatever goop you're using) and letting them dry before mounting them onto the rims.
