[quote=wuming;207530]Thanks for that. I found it much harder to break the bead on the second side; are there any tips/techniques to make this easier? Like you say, I need more practice; I'll try and find some more screws to ride over
. I found a good thread over on ADVRider which others may also find useful for this problem.
Keep an old tire handy, somewhere in your garage or shop. Could be car or bike if bike and you only want to keep one, keep a rear. When you have the wheel off the bike, put the old tire on the ground flat, and lay the wheel on top. A mounted spare from a car works good for this as well.
Deflate the tire by removing the valve stem. Stand on the tire you are removing so that your feet are on the tire (but not on the rim) at about 4 Oclock and 8 Oclock. Bounce up and down. Apply soapy water to the rim and tire. This always worked for me except once, in that situation I clamped the tire in a black and decker type work mate so that the clamping part squoze the tire just below the rim. I had to then wiggle the wheel a few times and finally it busted loose.
All of the above applies to tube tires mounted on rims that must have tubes. Tubeless tires I take to the tire shop. Tubeless rims have a different construction that makes it harder (impossible) to break the bead without a proper tire machine. An automotive tire shop can break the bead if they are careful should you need this done and there are no bike shops handy. A machine for breaking beads and mounting tubeless tires is not horribly expensive IF you are going to do lots of tires. Local bike shops charge 20 bux on average, so here, after about 15 tires you have paid for a machine YMMV.
