Tyre bead

**Premature Accelerato** · 30th July 2014, 14:23

Anyone have any bright ideas. I have just change a tyre and I cant get the bead to pop. Have put on heaps of soapy water, bounced it up and down, massaged the tyre on rim the, twisted it on the rim while I have the compressor air fitting on the tyre, none of it works. Have spent and hour or so on this and have given up. I did another wheel a few minutes before this one and had no problems at all. Tyre is a 180/55.

Some tyres are just arseholes. Try putting a heater on it for half an hour, get it up to so you can only just keep your hand on it then lube it up and try again. Also, what pressure are you using? If you're expecting it to seat at normal running pressure you could be there a while. I've had to go to 90psi before now, near shat myself when it went... Not that I'm recommending that much, but have a wee google to see if you can find the manufacturer's max pressure, or at least a reference from a tyre pro.

Have managed to get it on. I put the tyre/rim in an upright position, (as it would be on the bike), connected the tyre inflator which was taped in place with the trigger taped full on and then sat on the wheel bouncing slowly up and down. The bead caught and blew out very fast, just about crapped myself. Thanks for the reply ocean1. Perhaps I could have put the tyre warmers on. I know when I took a couple of tyres off last week that the carcasses were really stiff, I had put it down to the day being bloody cold.

Good job. So the bead wasn't seating well enough to get the pressure up eh?

There's a lot of tiny wee cheap compressors around that are good value, but that's one job a decent size machine makes easier.

Have you seen Uchoob footage of clever dudes using propane? Don't do that.
