    Flat tubeless tires. Whats next?

    I got a flat on my tubeless tires today and I cannot get them to reseal. So what do I do next. I'm assuming I'm going to have to buy a new tire but is it as easy as putting the tire on and re inflating or like I think is it a little more difficult.

    Why'd it flat? When was the last time you added sealant?

    When I mount new tires, if I have time, I mount them up with a tube and let them stretch out a little and then make them tubeless. So easy, I do it with a floor pump.
    I like turtles

    There flat because I got a rather large whole in the tire. I ripped it open on something just not sure what. I bought this bike about a month ago and the rocky terrain where I ride tends to destroy tires. This was my first tubeless setup so I had high expectations that it would be better which it was as I got no more pinch flats but I ripped through the tire. I have tubes so I can put them in but want to keep the bike tubeless

    These videos are how I learned to install tubeless tires. The critical factor for me was to get the beads of the tire wet with soapy water. Without that I could not get the tires to seal.

    have you tried patching the rather large hole? Then setting up the tubeless?

    Yeah... tubeless isn't going to stop large holes. Depending on the size though you may be able to patch it... or yeah, get a new tire.

    some people have had success with using dental floss or other thin but tough material to sew a tear closed using a baseball stitch. Then use a tire boot over it.

    I have never tried it.

    You can usually patch them depending on the location and size of the hole.
    1. Remove the tire and clean off all old sealant, dirt, etc. from the hole and area around the hole
    2. Let it dry. It needs to be super dry. If it's not, your patch is going to fail. You can use a hairdryer or torch if you're impatient, but this is probably the most important step.
    2. Scuff, vulcanize, and stick a rubber patch onto the inside of the tire per patch kit manufacturer instructions.
    3. Clamp the patch area with vice grips and something larger & flat- like an old set of brake pads. Let it sit that way for a few hours or overnight.
    4. Put that b1tch back on your wheel and ride. Don't do it the night before a race, because if the patch fails, it'll suck more than usual. As long as you get through a couple of good rides on the patched tire, you can probably bank on it being OK for the remaining life of the tire.

    I'm gonna make this a topic on JRA tonight if any of you listen to Mountain Bike Radio.

    It can't hurt to try and patch it, but if the hole has cut through too much of the casing cords, it's done. Sounds like you need a sturdier tire. Something like Specialized control casing or Schwalbe snake skin, continental protection, Maxxis EXO. Most tire manufacturers make something. Real XC race tires tend to be way too thin and fragile for rocky terrain.

    tyre patch stitched to the inside...not pretty but works. the sealant eventually seals the needle holes. By the time I start doing this the tyre is normally pretty worn out but it may be good for a new tyre to keep it going for a bit.

    What rim and tire are you running?

    The trouble with common sense is it is no longer common

    Bontrager Duster 29er with Bontrager XR3 Expert tires. Just waiting until I feel like I wore the tires out enough until I can justify to myself buying some Maxxis Ardents or Highrollers. I think the patch is working well now. I'm just struggling to get the tire to set without an air compressor

    Do you have the Bonty TLR rim strips and valves installed? Using the TLR version of the tire? Once the hole is repaired it will easily inflate and seat with a floor pump.

    Buy tubeless tires from Maxxis, make sure its has EXO, these tires are very reliable and durable.

    Agree. Arch EX rims and Maxxis tires solved my tubeless flats problems!

    Not sure, but I have a Maxxis Ardent 2.25 on the front and a Maxxis Ignitor 2.1 on the rear. They're doing great. All conditions. Tough sidewalls. My Rocket Ron's would roll off the rims in a hard turn. Not these!

    Holy crap, I'm amazed you did get that to seal. I've been a loud proponent of tubeless for many years but I personally wouldn't have even attempted that one. You sir have the skills and determination of a saint. And lol where the f*** are the knobs, is that a tire or a tube? I would've slid out the first ten pedal strokes and slammed into a tree on that tire.
    To appreciate the flowers you must also walk among s**t to know the difference

    lol your post made me laugh, probably because you are right on all counts...funnily I have another tyre like this but with about 5 of these repairs I took off because I think the tyre gets old and worn and slices really easily and I got tired of fixing it. Yeah, it's a bit sketchy but just for a rear I get by...will be replacing it soon though! Just secretly want to see how far I can push my gear

    I could see this in a pinch, but it's not a good solution beyond that one ride.
