I'm trying to install a new tubular tire once again. The problem is every time I do this I always get it wrong because I always have this area (let's say 10-15cm each way) around the tire's valve that kinda extends a bit so when I ride after the installation I always have this wobbling, which you barely notice when you ride slow but when you speed up it's getting kinda annoying and a bit scary.

I watched A LOT of videos on youtube, I used different kinds of cements, tape and ways of installation, but I can't get it right for some reason. Maybe it's because I use cheap tires or I need to do something after the tire is settled on the rim?

Please tell me what am I missing here?

  • Maybe pay a shop to do it once and find out if you have bad tire or rim. Why go tubular if you are going to cheap it?

  • @Frisbee I thought about getting it to the shop, and It's not about cheaping it. I like to do everything with my hands and I like to make things perfectly good too, so it's more about learning the right technique than cheaping.

  • @Frisbee Well it would be just because of the cheap tires the whole internet would swarm with bad testimonials about cheap tires, yet people use them, I assume, way more than expensive ones, without complaining. I still think I'm the one who's doing something wrong. Again I plan to go expensive ones, but I need to be sure that I can install them properly.

  • The likely problem is that either your tires are bad or you can't install them and money can solve both. The question says that the area around "nipple kinda extends", can you show that?

If you have got a loose area of tyre next to the valve, you need to 'distribute' this looseness to some other part of the rim.

Put a screw-driver across the rim under the tyre, and roll it around the rim away from the valve. The screwdriver will slip on the metal rim, but grip the tyre, so it will revolve.

Do this for both loose areas, each side of the valve, before you blow the tyre up. Once up to pressure, the tyre should run true, and be well stuck. Cheers... Pete

  • Won't that break the glue? I'm not convinced that the screwdriver will slide on the glue-covered rim as easily as your description suggests.

Yeah, the used to happen to me. I've found that the tube is not evenly distributed in the tire. Not surprising, with all the coaxing, levering, and finnagling to get the bead onto the rim.

What works for me is to massage/knead the tire. Yeah, sounds weird. So once you have gotten the tire into the rim, inflate the tube just a little bit. Then massage the tire, as one would do to bread dough. Maybe repeat this a couple of more times. I just do this once, myself.

Oh- and make sure the powdery stuff on the tube is present. This helps the tube move around as needed during inflation. Without the powder, the tube will grip onto the tire and won't expand and distribute evenly.
