    Tires: switching from 40-406 to 37-406

    Yesterday, I tried to swap out my 40-406 tires for some new 37-406 tires (Innova). I have never experienced such difficulty and frustration fitting a tire onto a rim. After two hours of pushing, twisting and kneading, I finally resorted to levers. Bad mistake. The tire eventually went on (although one lever bent in the process), but when I inflated it I discovered that I had obviously pinched and punctured the inner tube. My fingers and thumbs are rubbed raw from all the effort and I can't face trying again, so I've decided to use the LBS. However, another thought now strikes me. Assuming that said LBS manages to get the tire onto the rim and inflated, what happens if I get a puncture out on the road, in the middle of nowhere? Surely this can't be the way that things are meant to be.

    tire lube, the stuff they use to make tire switching easier? i've never used it, but I wish I had when changing my tires out.

    Shilun,
    Ask the guys at your LBS to show you how to do it easier...they change hundreds of thousands of tires in a lifetime. I did, and learned how to change tires much easier.

    You can also try a quick stick or speed lever which allows you to install and remove tires more easily than thumbs and fingers alone, esp. with the Schwalbe stuff.

    The quick stick is very durable, tough, and packable, while the speed lever is a little more fragile but easier to use. I have more experience with the speed lever, but got the quick stick because I was afraid of breaking the speed lever while trying to install a Marathon. They're both cheap which is always a plus.

    Talcum powder or WD-40 to provide a lube to the tyre edge.

    The Speed lever and Kool Stop speed jack work well:

    But the problem is that if the tire is really hard to get on, it will be really hard to get off! Plus, you'll have to carry a Speed Lever or Speed Jack when you ride.

    You can try replacing the rim tape with Velocity Veloplugs, which let the tire bead sit lower in the rim when mounting the tire. If those don't work, try different tires.

    Different tire brands definitely have slightly different sizing. I just changed the 406 tires in my folder. The old ones were very difficult to remove, even with levers, the new ones slipped right on with no tools. One almost slipped off too, but I caught it in time and let the air out. I have had the same experience with my full sized bikes, too.

    A quick update: I took the rim and tire to the local LBS. The guy there inserted a new inner tube, got down into a squatting position, and using his fingers in a pulling action, rather than pushing with his thumbs, had the tire on the rim in under 20 seconds! It was magical, and so fast it was hard to see exactly what had happened. I wonder if speed is the solution to this kind of problem?
