    Mounting a really tight tire on a rim...............

    This might be old news to this forum, but new to me. Recently purchased a Diamondback hardtail. The stock tires were so wide, and heavy, that I decided to go with a gravel tire with a file tread, as that is how I will be using this bike. I do have a fair bit of experience changing out bike tires, but mostly on road bikes. Removal of the OEM tires was a bit more difficult than I expected. The bead was really locked in, but it was done with hands and some tire levers.

    On to the mounting, and things got very difficult. I could not get the tire mounted. A quick consult with You Tube revealed that I was battling with friction. Once I lubed up the tire bead, and rims with Dawn dishwashing soap, I was able to mount the tires using just my hands. I was truly amazed at this technique. Just passing this on. I found a small container to store some Dawn, and will keep it in my saddle bag.

    Proper lubrication cannot be taken too lightly. There are actually a LOT of products in the moto industry to help getting tires mounted/beads seated. They can be used on bicycle wheels/tires.

    By way if you over inflate them for a few days (when not riding) they shouldn't be nearly as bad the second time if you get a flat on the road.

    Ahh yes, mounting tires will never be the same since the advent of tubeless compatible rims. I started a similar thread here:

    https://forums.roadbikereview.com/wh...ad-367715.html

    One of the mechanics at my shop claims the only way to dislodge the bead on some tires is to place the rim on the ground and step on the bead.

    I'm not sure Jay's method would work on a tubeless compatible tire. And I have to wonder how much I could over inflate the tire before I risk deafness.

    For those stubborn tires, get yourself a Koolstop tire bead jack. I've never met a tire/rim that this didn't make it a piece of cake to get on.

    It helps on tubeless as well.

    Just inflate to the max recommended pressure, which is always way "over inflated" from actual riding pressure.

    Get on, yes. Get off, no.

    Yes, per thread title "Mounting a really tight tire on a rim..............."


    As far as getting off, I've never had an issue getting a tubeless tire off with normal levers. (not that I've tried every tire)

    Another thing that works (without leaving soapy residue) is baby powder. People use it to make inner tubes more "slippery" so thy don't stick to the inside of the tire, and if you put it on the bead, the tire will pop into the rim groove more easily.

    Try getting a WTB Byway tire off a WTB KOM rim sometime. The tire and rim are virtually inseparable.

    I'm not saying that saliva is on the same level as Phil Wood waterproof grease or ProLink. Or Dawn or WD40.

    But saliva is the next best thing, except for ProLink, which we all know you love nearly as much as I do.

    You mean this:

    I wonder if putting some of that on the shifter cable where the shifter wraps it would extend the time before it frays on my Shimano "I love to eat cables" shifter.

    Late to the party, but how about talc powder? Not quite as slippery as liquid, but does the job, IME.

    Rub talc around the spare tube before folding it up and putting it in the sandwich bag, and it'll go on nicely replacing a flat on the road. It allows the tube to slide and seat properly when aired up; doesn't "catch" inside the tire flexing over the "flat spot" or bumps; therefore some claim it even lessens rolling resistance.

    It doesn't weigh anything, take up space in your kit, and leaves no residue.
