Hi, Trying to replace my continental ultra sport clincher tyre. I have never replaced a tyre before :? . I have tryed to use the tyre levers to remove the tyre's two beads which run round the wheel. But the tyre does not seem to detach from the rim. Please help.

    Some tyres are easier than others to remove eg folding tyres that do not have an internal stiffening ring are a bit easier than those with the stiffening ring.

    In general you should not have too many problems if you equip yourself with some decent tyre levers.

    Attached video gives you the general principles:-

    They could be tight because of the type of tyre they are (folding, non folding, make, age, use, etc) or they are old and no talc in there has essentially caused them to stick against the wheel rims and the tube against the inside of the tyre:

    Make sure the tyre is completely deflated. Then, starting at the side opposite the valve, lever the tyre off one side. This shouldn't be too bad if you get a lot of force into it, although it may take a few goes to get the lever in there and the tyre off.

    Then wearing a pair of gloves (because 8 times out of 10 the lever slips and you smash your thumbs into the spokes causing much aggro, akin to stubbing toe on bed) grip the wheel between your knees and push the lever round - it will be as tight as hell. The glove also means that you can get more force into the lever as it won't cut into you.

    Sometimes I find that being pretty brutal with it does the job - just grab the lever with the whole of your hand and force it round - you won't damage the wheel at all and the worst you can do it tear the tube.

    Alternatively, some people lever the tyre up, release "x" amount of tyre from the rim, then use the lever to prop the tyre up. They then get a new lever and continue from that point.

    Once one side is up then Murphy's Law says that you'll have to do the other in exactly the same way.

    If the tube is stuck to the inside of the tyre, just pull it out, inspect, put in plastic bag full of talc, shake, then re-install into the wheel once the new tyre has been half fitted. If you get talc all over the tyre as well it won't make life any harder, some people say that it actually helps.

    Assembly, as they say, is the reverse of disassembly.

    Dependant on what tyres you are fitting, they may also be a sod to fit, but persist and it'll be fine.
