The tyres on my bike are both continental ultra gatorskin 25`s, they are also both the folding type. I bought them because the guy at LBS said they were "better " .

Whats the advantage with foldable tyres ( if any ) over the sort you can do the hoopla with ?

    Folding tyres tend to be lighter - this means that they have lower rotational mass.

    They also tend to be easier to fit than those with steel beads.

    Most of the better clinchers come in folding only anyway, but I still reckon getting folding is worth it for the cheaper tyres.

    Folding tyres have kevlar beads, as opposed to the others which have steel beads. From my own experience, steel beads tend to stretch a bit with time, which may cause problems. It's easier and cheaperfor my mail order supplier to ship folding tyres; when I go solo on a very long ride, I can carry a light folding spare in my backpocket. Try that with the "hoopla's"! :wink:

    Lighter, and kevlar is also more puncture resistant 8)

    Lighter, easier to store, generally easier to fit.

    Kevlar has less puncture resistance than steel in my experience. But I've never had a puncture through the bead, so that's mostly immaterial.

    The bead material has nothing whatsoever to do with the puncture resistance.

    You are getting confused between the kevlar bead and a kevlar weave underneath the rubber tread explicitly for puncture prevention.

    And if it's a non-kevlar weave under the rubber tread?... It's then a steel weave, no?! :shock: :lol:

    How many road bicycle tyres do you see with steel puncture protection? none I bet.

    As I said before FOLDING TYRES AND KEVLAR BEADS HAVE NOTHING TO DO WITH PUNCTURE PROTECTION

    Some tyres use a glass fibre weave, I believe (Aramid?).

    If you've never had a puncture "through the bead", what would your "experience" be exactly?

    How the hell do you get a puncture through the bead? You'd have to puncture through the alloy rim first.
