Thanks for the quick replies and welcome. I should have mentioned in the first post that the rim is in quite poor condition internally. It has corroded quite heavily around the spoke nipples which I'm guessing is why the previous owner went down the tube route. A fancy new rim band and a tube of silicone would maybe solve it, but I quite fancy sticking with the tube knowing the state of the wheel. I did apply plenty of thick rubbery tape I had in a rim band sort of formation to protect the tube from the rim, so that shouldn't be causing me any issues. I'll try and get hold of another tube and give it a go minus the rimlock. What you say about it not allowing the tube to inflate evenly does make sense. I used THIS tube if it makes any odds. Thanks again.

Hi, New to trialscentral so go steady on me. I've recently bought a 2004 Sherco 2.9 and I'm having a bit of a problem with the rear wheel. Someone in the past has fitted a tube in the rear tyre, and drilled the rim for a rimlock. I set about changing the tyre when I got the bike and managed to nacker the old tube when removing it. I bought a new 'heavy duty' 400/450-18 tube and assembled the lot, got the tyre on the rim fine, beadlock seated properly, plenty of soap, then started inflating. I couldn't for the life of me get the bead seated all the way round. There was a section on either side which wouldn't budge. Deflated, re-soaped and tried again to no avail. The tube then burst at ~45psi along the seam. So where am I going wrong. I realise it's going to be a tight fit with it being a tubeless rim and tyre, but I don't see how I'm going to get the thing seated. I read in another thread that tubeless tyres usually pop onto the rim at circa 60/70psi with soap, but I'll not get that into a tube if it burst at 45! Any help appreciated, I'm running out of patience and want to get out for a play on my new toy after a 7 year break! Thanks, Chris
