Folding Tire too Tight for Rim

B.D A little dish-soap helps sometimes. Makes grabbing the rest of the wheel hard if you get it all over the place, though. Nice supple tires like those tires will loosen up a bit after they have been mounted. Flat tires like those (and Veloflex, etc) go on nicely if you get the first bead toward the middle, and fold the tread over in a way. So it sort of looks like an uninflated tubular. Make sure with nice wheels and tires like those you have tubes that are fast too. It would be a shame to waste a combo like that with slow tubes. Joseph |

B.D Three things usually work: 1) Try fitting it without the tube first, using tyre levers. Sometimes this stretches the bead slightly. 2) Get loads of talc on the tube. 3) Before the final push, check the beads are in the middle of the rim everywhere else round the wheel. The good news is that kevlar beads always become much looser after a couple of weeks on the rim, so subsequent puncture repair isn't the nightmare you'd expect. ....and as a coda to this, I removed a Vredestein Fortezza - the tightest tyre I've ever had to fit - using two hub QR levers yesterday. No problem. |

Folding Tire too Tight for Rim
Nearly all folding tires are built undersized because, unlike steel, the
kevlar used for the bead stretches somewhat. One good tip I've heard is to mount a new foldy on a spare rim and store it slightly over inflated for a while. this pre-stretches the bead a little, making mounting easier. It's actually an old tubular (sew-up) trick. - - Compliments of: "Your Friendly Neighborhood Wheelman" If you want to E-mail me use: ChrisZCorner "at" webtv "dot" net My website: http://geocities.com/czcorner |

B.D Lots of good tips posted already, but if and when they aren't enough for you, /the/ tool, IMHO, is the VAR tire tool. It's #425 on this page: http://www.sheldonbrown.com/var/pages/var0051.html It works, period. I've got several and wouldn't be without it, having several tight tire/rim combinations in my stable. (True, most tires need no levers at all, but some /do/) My US sources for this tool have dried up (Terry bicycles, third hand, etc.), and a quick Google only found me UK sources, but I'm sure you can find them if you want to spend more than a few minutes looking. Best of luck, Mark J. |

B.D Rim tape can occupy lots of room you might need to make installation of a tight tire easier. Try VeloPlugs from Velocity (I think they'll work on a HED wheel), or the very thinnest tape (Zipp makes nice thin but protective tape and I like Ritchey snap-on rim bands for tighter rims) to free up every micro-mm of space possible. Velox rim tape takes up quite a bit of room and is not my first choice when tires are twight (like tiger)... I think HED rims have no channel in the center of the rim bed which makes installing tires tough... Watch this vid and see if it helps... http://www.cycleto.com/index.php?vie...ntent&Itemid=3 |

No offense intended, but I'd like to shoot this vid over and give Mr. Beefy the old (cheap, wire bead) Conti tire and Campy rim combo I had back in the day. "Heel of the hand", my ass. Yeah, let's show all the ladies how to take a flying locker lip on that valve stem! Hey, some candle light, a little wine... --D-y |

The video shows the installation of a tire which is pretty loose. If the tire is tight, he wont be able to get it in so quickly. He will need to go around the whole tire to get the beads in the middle of the rim. Once he does that, it may still be very tight. He will need to try to roll the tire in with his palms, but he won't get enough force to do so from that position. He will probably have to put the valve side of the wheel on the floor, and the opposite end facing up. Using his weight and a lot of strength he may be able to massage and roll the tire into the rim.
