Tyres too tight for rims. Help!

Trying to fit Hutchinson (Python and Toro) tubeless tyres onto Hope Hoops with Crest 29er rims. Holy crap - they're tight! (and they're not 26" tyres by the way...) :wink:

They are so tight that I have tried for 40 minutes to get one on and have failed miserably.

Any clever suggestions as to how to get really tight tyres on a rim????

    Watch the video on you tube on how to fit schwalbe marathon tyres.

    Most people forget how to fit tyres.

    On some barons which were being absolute swines, a squirt of silicone spray helped a lot !

    I can't even get the first bead on. He only shows how to get the second bead on. Mine is much tighter than his unfortunately...

    That does it! I had an issue fitting Schwalbe Big Apple 2.35 slicks to my skinny rimmed commuter. Lots of washing up liquid and a "decent" tyre lever did the trick

    i thought i read somewhere on the NoTubes site that Hutchinson tyres are not recommended for there rims??

    EDIT: ok maybe not, just the Air Light version of Hutchinson.

    Those rims are horrendously tight. Basically they increased the bead diameter slightly to make tyre inflation with non-tubeless tyres easier. Unfortunately at the same time most manufacturers started doing tubeless ready type tyres with a smaller bead, to achieve the same thing!

    Make sure you're fitting them right, a decent tyre lever won't go a miss either.

    If you're not already - assuming it's the same principle as the Stans 26" rim, get the bead into the centre groove as you go around...(the deepeset part of the rim....the rest should then be easier to mount)

    My Sun rims are stupid, managed to snap a park lever getting my last tyre on. Some rim tyre combos need at least metal cored levers. I hate my wheels so I just use steel ones.

    For stupidly tight rim tyre combos either Park Tools steel core levers, or maybe one of these: http://www.sjscycles.co.uk/simson-tyre-mate-prod22353/

    If you place a piece of electrical tape on the rim (maybe doubled up) you could use metal tire levers without damaging the rim.... Once the tire is on, peel the tape off...

    My concern would be that if you get a flat / tear / hole, what are you going to do about repairing?...

    I reckon after you've been riding for a while the beads stretch a bit on the wheel due to the movement so this won't be too much of a problem... hopefully?
