  1. Last night I was trying to mound Kenda Kwick 1.7" x 26" folding tires onto old Bontrager/Weinmann
    rims. Other tires mount easily on these rims, and the other Kenda tires I've used seem to go and off
    easily. I was using tire liners (the correct size for these tires), but in the past those haven't
    made it impossible for me to get the bead over the rim. I also had the correct tube size.
    Additionally I'm using the thinnest rim tape I've seen, and it is in the center, leaving the bead
    area bare.

    First I couldn't even come close to getting these on by hand: I had to without pry them over the
    rim. When I ran out of what I could mount with my hands there was more bead unmounted then I've ever
    seen on any tire before. When I tried to pry them over the rim with a skinny plastic tire lever, it
    snapped. When I used a thicker tire lever, the rim deformed slightly, although the tire did go on.

    What gives? I've installed tires for ages, and never encountered a problem like this. How do you
    mount extremely difficult tires without destroying the rim?

    Once upon a time, there was a thing called a tire jacker. I don't know if they still make them or
    not. What it was, was a forked piece that sat on the edge of the rim and a hooked piece that pulled
    the bead up and over. Worked like a charm, so I bought one. In the almost 10 years I've owned it,
    I've maybe used it twice...

    Lots of times, all it takes is a strong grip. Use the joint between your fingers and palms and roll.
    My thumbs aren't usually strong enough to get that last little bit.

    If you haven't screwed the tire up, maybe you should think about exchanging
    it. What happens if/when you get a flat out on the road??

    I'm aware of that, but it's only partially a concern. I'd given this bike to my wife to replace her
    stolen bike, and I've been setting it up the way she likes it (grocery-getter/ commuter style). She
    has never changed a flat in her life, and wouldn't do it even if the tires were easy to mount. On
    her old bike I used slime tubes. Since I haven't seen pre-slimed ones in presta, I've tried
    tire-liners with this bike.

    Keep most of the bead from both sides of the tire centered on the rim.
    Use tire talc to make things slide more easily.
    Some tires are very tough to mount.
    When I get one of the tougher ones I put the entire wheel in my "lap" with the mounted portion at my waist and the "to-be'-mounted" section at arms reach. I use the heals of my hands the finish the process, while hooking my fingers over the tire.
    I hope you can picture the process.
    Remember to check that the bead hasn't trapped the tube between the rim and tire. Also clean any remaining talc of the rim with a damp rag before you try applying rim brakes. Clean the floor too, as it get slippery.

    Sometimes you get a tight fit, when there's a tire on the tight side of average, and a rim on the
    big side of average.

    Squeeze the beads together, and jam them down in the rim bed as far as possible, to get as much
    clearance for the tire to slip over the rim on the other side. Sometimes thinner rim tape makes this
    possible, where Velox is too bulky.

    I agree. I used to have a set of Continental Avenues, which were wonderfully fast, but way too
    difficult to get on and off. I couldn't do it without drawing blood, even with sturdy tire levers.
    So I got rid of them.

    Being stranded by a flat is worth considering. With so many different tires available, there's no
    reason to put up with this.

    Perhaps someone could recommend a similar tire, which they have no trouble with on their own
    Bontrager/Weinman rims.

    David

    Apart from the advice yo've already gotten. Don't forget to start as far away from the valve as
    possible. Closing in from both sides towards the valve. The reason is obvious of course since the
    valve is the only place you cannot get the beads down in the center of the rim as is the last place
    you are closing.

    What you can get thats very similar to what you describe is a VAR tire lever. This lever pulls the
    tire over the rim and doesn't damage the tire, tube or rim as its made of plastic (note - don't use
    in really cold weather as supposedly it could crack). I've NEVER had a problems mounting any
    clincher tire on a rim with this tool. For more info see here:

    I've seen a few "easy tire installation" gadgets in the past, at bike shows, but never in the "real

    Au contraire! The esteemed Crank Brothers make a portable version of this tool called the Speed
    Lever. It slides open and closes to about the size of a 3-pack of small tire levers. It does both
    on and off, and the tool surfaces looks very much like the Terry bead jacker seen elsewhere in
    this thread.

    If you need more convincing, it's actually cheaper than the Terry tool, despite being more tool, in
    my opinion.

    In practice, my results have been mixed but mostly positive. At first, I found that when I tried to
    use it to whip a tire off the rim as it suggests, the friction between the tire and the tool was too
    high for it to move. I had to use a conventional lever to help things get started.

    That said, spitting on the tool (suggested in the product FAQ) does help things greatly, and a few
    uses seem to have also broken it in a bit. In all, I would probably buy it again (if only because
    it is so conceptually cool), and I like how it works in practice, but wished it worked a tetch
    more easily.

  14. I recently purchased a telescoping tire lever by Crank Brothers, and it was really helpful in
    getting some tight tires onto my rim. One end attaches to the axle, the other goes over the rim and
    tire and by rotating it around the rim it forces the tire in. It sells for around $6 so it's worth a
    try. Park makes what appears to be a heavy duty version, but it isn't telescoping so it can't be
    taken on the road.

    Ditto on the Continental Avenues. I could get them mounted with lots of brute force and various tire
    levers but getting them to seat correctly when inflating was near impossible. They'd never hook onto
    the rim correctly resulting in bulges and dips. The only way I could EVER get them correctly seated
    was by applying liberal amounts of dishwashing liquid to the inside of the rim and over-inflating
    the tube. (for the record.. one can inflate the conti avenues to over 115
    PSI... scary stuff! the side-wall rating is 80 max).

    I've since replaced the contis with a pair of 26x1.2 Kenda Kwests which are easier to get on, WAY
    easier to seat correctly and really fast

    extremely difficult tires without destroying the rim?

    lots of other posters gave excellent advice. my paltry additions:

    -sometimes something slippery, more slippery than talc, can help. like detergent.

    -the muscular brutish hand motion used to force tight tires on is not intuitive becuase it Hurts.
    every once in a while when i get one of those ridiculously bad fits, i come away from the job with
    what amounts to a frikkin' burn on my palms😉

    -koolstop (i believe) distrubutes a tool which is as best as i can tell analogous to the
    'tire-jacker' device mentioned elsewhere. it costs something like 5 bucks wholesale from qbp, so an
    LBS can order
    it. it is a burly looking black plastic tool that gives you some non trivial leverage for getting a
    tire on, but greatly reduces the risk of pinching the tube (nothing quite eliminates it,
    AFAIK). there is also a smaller, portable device that i bought. for a few bucks. it is grey
    plastic, and uses the same principle, but with a less robust, and much smaller design. it
    doesnt have a manufacturer stamped on it, and i cant remember where it came from. it might be
    convenient for tight tires on a roadside flat, but frankly i have only used it once or twice.
    for everything but the tightest tires i use my hands. for the true beasts i use the invincible
    kool stop import.

    i really like tire removal and installation tools. for some inexplicable reason. this is off topic,
    but my system is as follows: for 90% of flat tubes, i get the tire off with one park tl-1 tire
    lever, which i appreciate for its unbreakableness and smooth edges, and get the tires back on by
    hand. for the tough tires to dismount, i use a pair of the big park metal shop levers, until i can
    slip the blue plastic lever (rim friendly, hand friendly) in and slide it around the circumference.
    if im on the road, i woudlnt take those huge shop levers, but would instead take a pair of small
    metal levers. i have a trio that i modified with a grinder and a file so they are much easier to
    dismount tires with. and to get them back on, either hands or the koolstop thing.

    thigns i dont like: just about every single plastic tire lever on the market, except for the park
    tl-1, and the ones that come with mavic wheels.

    I don't want metal tire levers--I haven't used those for ages. In this case as I mentioned in the
    first post, I bent the rim slightly with a plastic lever. I don't think metal would do better there.
