March 28, 201115 yr Hi all I have just changed my front tyre to a michelin x11 2.75 x 21". I had this fitted by a local bike shop, when i collected it he said he was having difficulty beading the tyre. He said every time he let the pressure down it popped of the rim and said to leave it over night with high pressure in to try and seat it correctly. I tried this but it still popped off. Please help Adam
March 28, 201115 yr Make sure its a "tube type" tire. Michelin made tubeless front tires for the old Aprilia's that have a different seal bead than the tube type. I was given a tubeless front tire years ago and tried using it with a tube type rim. had the same problem. Hi all I have just changed my front tyre to a michelin x11 2.75 x 21".

March 28, 201115 yr I had this many years ago with a Michelin, chasing the "bad" bit round the rim trying to clamp it with the security bolt to no avail. Michelin took it back as it was a faulty tyre. Give them a call.
March 28, 201115 yr check what tube is in it .if its a enduro h/d tube this will be the fault.they are o/k in a motocross or a enduro wheel when they are used at a higher pressure.
March 28, 201115 yr Author Ok will check the tube, how will i tell if its a trials tube or enduro tube? i will also give michelin a call Adam
March 30, 201115 yr Author Update I have been in touch with michelin who were very efficient and called me back within half an hour once i filled in a short questionaire, very impressed. Right the info he gave was to change the tube to a michelin tube and try that. I have tried this and still the same results. So the only thing it could be now is the tyre or the rim. The rim looks good but does has some slight bows in places where it must of taken a dink when the tyre has fully depresssed on say a rock. But the tyre technition says its not effecting the seating area of the rim. So going to call michelin again and speak to the same technical guy as he gave me his direct number. I am new to all this but surely its not usual this difficult to fit a tyre Adam
March 30, 201115 yr Author P.s The original tube was imo very good quite thick kept it shape when nearly flat, and was made by continental Adam
April 2, 201115 yr Author Update I tried a different tube and another brand new tyre and still had the same problem, i assumed it was the rim. I then took the wheel and tyre to Martin Sandiford from sanifords offroad to let jeff the mechanic have a look. He refit the tyre and replaced the tube as he said this was at fault with one he had lying around and the tyre was fit and seated correctly once and for all. Dont know what the original tyre guy was doing wrong but its on now on and will get tested tomorrow up whitworth. Thanks for all your advise and thanks to Jeff Adam
