copemech Posted July 7, 2007 Report Share Posted July 7, 2007 There are some tires that will almost "bead up" by themselves, but many will not, and a few that will not no matter what straps you use. The beading "tool" is the only way to go! Once you get them to "hold air" you still need to get them to 'seat" properly over the hump in the bead area of the rim. Once again, some will go easily and others NOT! This is where a proper tire mounting lube comes into play! Same goes for the front as far as getting them to "bead up" and go straight! I gave seen some real ******* cases. And it is not the tire, it is the variation in the rims that makes the difference! A mm here or there will put you off and have you screaming at it in no time!

peterb Posted July 7, 2007 Report Share Posted July 7, 2007 Never read so much to do with changing tyres. Over this way, some of us use a vice to clamp the deflated tyre and twist the wheel to break the bead carefully using WD40/CRC penetrating oil. My good friend is thinking about making a proper bead breaker and if this happens, will post some photos. For refitting, we use a length of dairy milking hose, its a thick walled rubber hose about 25mm diameter, with a longer length of string in it to give you something to pull the hose out of the way when the tyre inflates. This works like the suggested 14 inch inner tube method, fit the tyre into the rim well, push in the hose to take up the room between the tyre and the rim, with the two ends of the hose meeting together, then inflate with a compressor using lots of soapy water. Never failed to work. Sometimes works with a good foot pump, but very hard to bead out the tyre. Bye, PeterB. Quote Link to comment Share on other sites More sharing options...
