Changing tyres ???????
 

Hiya all..

I tried to change my rear tyre for the first time this weekend and after some tiresome work think I managed to get the job done, the only thing is that I noticed on the way into work this morning that when I'm riding and I look back at the wheel there seems to be a slight buckle, the wheel is on straight so I can only imagine that the tyre isn't, do you know of any quick fix's for this, I imagine the bead isn't sitting completely right on the wheel. Is and option to over-inflate the tyre to get it to seat properly?

Any suggestions, advice welcome?

I had the same problem once...and I went to a motorcycle tyre place around the corner with my tail between my legs, to ask their advice. They were really cool about it and showed me how to sort it out. Basically there is a sort of 'rim mark' around the tyre which should be pretty much evenly spaced from the rim all the way around. (I'm not sure if this is there on all tyres). On my wheel this rim mark was below the rim on one side and above the rim on the other. What you should try to do is deflate the tyre, pour dish liquid along the section that appears mis-aligned (make sure it gets between the rim and the tyre) and then pump the tyre up (overinflate it if necessary) and it should slip into place. Do this both sides. It certainly worked for me. Don't be shy with the dish liquid...but remember to wipe it off afterwards because it's as slippery as hell!

Thanks for the advice Paul....

Still seem to have the problem, the part of the tyre that won't pop onto the bead is the same part of the tyre that I last put on. So when using the irons to put the tyre back on the rim the last part to get over is where the tyre won't sit properly, is there a knack to putting over the last bit??
I've done about 50 miles with it as it is, does this make a difference when trying to correct it??

Thanks again

hmmm, what a pain. Have you checked whether the valve is at the area where it is not sitting properly? I have had a situation where the bead got stuck on the raised bit of the tube where the valve is attached.
Another option is to lift the section of tyre which is causing the problem back out of the rim and then pop it in again.

You are right, its doing my head in, even took it out for a high speed run to force it to pop into the right place...I will try again tonight and take it out and try put it back in really carefully...its not by the valve or rim lock so its ..dunno what it is..but ya have to keep laughing and give it another go...will let you know..

Thanks for the help..

At last, took the tyre off and put it on again, made sure it was even as possible on the rim and voila, it worked.

Thanks again.

When you start levering the tyre back on, push your knee onto the tyre opposite where you are levering. The idea is to push the bit of tyre under your knee flat and into the wheel well. This gives you more room to lever the tyre on and often means you can push the last bit of bead on with the heel of your hand. It also means the tyre is more evenly distributed around the rim to start with. With plenty of lubrication (get the proper stuff rather than washing up liquid if you can) It should seat itself with a bit of a bang at about 40psi. Apart from when you're in a hurry of course. It has to be said that I've seen even proffesional tyre fitters with machines struggle to get Continental TKC80 tyres seated evenly.
