    noob question regarding tire bead

    hello,

    just attempted to slime my own tires and was successful until i tried to put back the tire onto the rims. in doing so the fabric that holds the bead in place separated and now i need a new tire.

    question

    how do i prevent this problem from occurring again?

    i had only worked on this particular tire 3 times in the past. is it that the tire was just crappy (it came stock on a new bike)? it was a continental ultra sport 700x23c. or do i just not know how to put the tire back onto the rim? seems that the act of trying to get the final few inches of the tire on the rim rubbed the fabric against the rim causing it to fray and rip.

    any advice is much appreciated.

    thanks

    sorry if this has already been posted. the search wasn't working.

    Don't be too rough on it. Don't use tyre-levers.

    Were the tires new or used?

    Make sure that the bead at the opposite side is right in the middle of the V between the rim sidewalls. Start putting on the bead opposite the valve and finish at the valve.

    The tires were new.

    I will try the suggestion of pushing the bead into the center of the rim to get more maneuverability for the final few inches. Maybe try the windex trick as well.

    A bonus was the bike shop switched out the tire for free.

    If you finish at the valve, make sure you push the stem up into the tyre to make sure the tube is not pinched.

    When you removed that tire those 3 times, did you do so by running the tire iron around it? That can be the start of fraying beads. I admit I do that myself sometimes when I'm in a hurry, but we should avoid that.

    Sometimes, I think it's less stressful on the tire to just finish up putting it on the rim by using a plastic tire iron than it is to force it over by hand. Some tires are just too tight no matter what you do, especially kevlar folders.

    I suggest the Kool Stop tire-jack or the similar VAR Super Tyre Tool. These will mount even the most obstinate clincher easily. Looks like an upside-down wishbone. One side mounts the rim on the side you can get the bead on. The other side straddles the rim and tire and has a hook which grabs the bead you can't get on. Pull back and it pulls the tire/bead up and over and into the rim. Pop! That simple.
    How do you keep an idiot in suspense?
