tire slipping off the rim
I've had some 1.5" slick tires mounted on my commuter bike (old hardtail
mtn bike) for a couple of years. This past winter I didn't ride the bike at all, and I finally brought it out of the garage this last weekend. Of course the air pressure was low so I pumped up the tubes. But now the tire on the front wheel no longer stays on the rim. As soon as I get something like 20psi into the tube, the tire slips over the rim. What gives? The tire is a Tioga 26"x1.50" city slicker, and I'm using a 1.50" tube. The rim is old, I don't know what it is off-hand (probably either a Sun or Mavic). I don't have much time for fooling around with bike stuff these days, and I'm not sure if I should go out and get a new tire or if I need to upgrade the rim/wheel. Getting a new tire would be the easiest thing to do, but I don't want to spend $30 on a tire only to have spend another $200 on a new wheel. Any suggestions? thanks |

Pump up to ten or fifteen psi, then disconnect the pump and bounce the wheel a bit to make sure the bead gets seated. The wire bead likely got a little warped from sitting around flat. Nothing to worry about. |

Seriously. $200 should get you a *pair* of really good wheels. $15 will get a decent (if not stylish) slick in a 26" size. Chances are good that the tire is all you need, but if not, then the wheel would be a prerequisite no matter what else you did. -- Typoes are a feature, not a bug.
