How To Repair A Tubeless Bike Tire

Tubeless tires take revolutionized mount biking. Yous can run lower pressures, pocket-size punctures don't end your day, and pinch flats are a affair of the by.

Just, eventually, you will put a hole in your tubeless bike tire. It might be a pocket-size puncture that your sealant can't quite take care of. Or it could be a big tear in the sidewall. Either way, you have to fix it.

Here's what to practice when things go wrong with your tubeless setup on the trail. We'll start with the easy stuff.

What to Do When Your Tubeless Bike Tire Burps Air

If you land hard, rail a corner at loftier speed, or hit a stone in the wrong way, your tubeless tire tin "burp" air. All this ways is you knocked the tire dewdrop off the wheel and lost some air. It'due south no large bargain, but it makes it much harder to ride.

When yous do this, there'south only one fix: put some air back in the tire. Use your pump or CO2 inflator to go it support to pressure. (Nosotros'll talk about a pump vs. CO2 in a bit.)

The best way to deal with tire burps, though, is to prevent them in the offset place. In that location are lots of theories on how to forbid tire burping, but most of them come down to two things: run plenty pressure and don't employ a big tire on a pocket-size rim.

Syntace's graphic shows exactly why a narrower rim tin can cause loftier-book tires to burp.

"Plenty" pressure, of class, depends on your weight, riding style, and terrain. There'southward not much you lot tin do here except experiment. But if y'all discover something that seems to piece of work well, be wary of going any lower. If you lot go through a corner at loftier speed, yous'll put a lot of lateral pressure on the tire, and that can unseat the bead.

As for tire choice, look at your bicycle width. If you accept a xxx–35mm wheel (or fifty-fifty wider), y'all can run a big tire without risking the bead coming off. If y'all're on a 25mm bike, run a smaller tire (maybe in the 2.25″ range) or more pressure.

Pay close attention to how ofttimes you lot burp your tires. If it's happening a lot, change your tire setup.

Sealing a Puncture With a Tubeless Tire Plug

Tubeless sealant is great when you have little punctures—thorns, small pieces of drinking glass, and small rocks generally don't pose a problem.

But what if you go a bigger puncture than that? Your sealant might not be able to deal with a roofing nail, for example.

In cases like this, a tubeless tire plug can be a lifesaver.

There are many kinds of tubeless tire plugs, simply they all piece of work on the aforementioned principle: you use some sort of tool to insert a small slice of sticky rubber into the puncture.

18-carat Innovations' tubeless tire plug is a popular option.

Afterward you remove the tool, the plug keeps whatsoever air from escaping. And yous don't fifty-fifty need to take your tire off of the rim. Here's the process:

1. Find the puncture.
2. Remove the offending object.
3. Insert the tire plug, following your particular plug'due south instructions.
4. Reinflate the tire using a pump or CO2 cartridge.

In about cases, this will solve the problem. Larger punctures might crave multiple plugs.

When you go home, you can remove the plugs and apply a proper patch. Or you can exit them in. Some people have left them in for months or years without whatsoever leakage.

Putting a Tube in a Tubeless Tire

If you don't have plugs, or you lot have a puncture that's too big for them, yous can install a tube. The process is the same as putting a tube in whatever other tire, with a couple of exceptions.

Here'due south how y'all do it:

1. Remove i side of the tire from the wheel. (You might need a burly tire lever to become the bead off the wheel. Metal and heavy-duty plastic options work well.)
2. Cascade as much sealant out of the tire as y'all can.
3. Remove the valve stem (unscrew the nut around the stalk and button information technology out through the inside of the rim). Don't forget to nothing it into your pocket or pocketbook.
4. Insert the tube as normal.
5. Reseat the tire bead.
6. Reinflate the tire using a pump or CO2 cartridge.

At the end of this process, there's a adept take chances that both yous and your bike will exist covered in tubeless sealant. That's merely how information technology is, and so don't worry about information technology.

Using a Tire Boot for Sidewall Tears

A sidewall tear is nearly every bit bad as it gets. Large gashes in your tires are difficult to deal with. When your sealant fixes a small pigsty or you put a tube in, you can ride pretty normally back to the trailhead. Merely if you gash your sidewall, making it back without having to walk is the best you can hope for.

The best way to repair a sidewall tear on the trail is with a tire boot. A boot is only a slice of material that covers the tear on the inside of the tire and keeps air from leaking out.

You have two options for tire boots. You can use a purpose-made tire boot or rig one up yourself. A professionally made tire kicking usually has adhesive on 1 side so you can stick it to the inside of the tire and seal up the tear (exist certain to clean the site equally much as possible to get better adhesion).

Park Tool'southward emergency tire boots are a skilful bet . . . but so is duct tape.

If yous desire to rig 1 upwards yourself, yous tin can use merely about anything: duct tape, a piece of an former tube, an energy gel packet, even a $20 bill.

No thing what you utilize, you'll take the same steps as you lot would for inserting a tube, with some minor changes:

1. Remove i side of the tire.
2. Cascade as much sealant out of the tire as you lot tin can.
3. Remove the valve stem.
4. Clean the site of the sidewall tear.
5. Insert the tire boot then it covers the tear (apply the adhesive if yous're using a ready-made kick, or endeavor to stick your kick where it won't slip if you're non).
6. Insert a tube.
7. Reseat the tire bead.
8. Reinflate the tire with a pump or CO2 cartridge.

Be extra careful when you're riding dwelling house on a booted tire, specially if you used something without agglutinative.

Air vs. CO2 for Tubeless Tires

In all of the repair instructions above, y'all finish past reinflating the tire with either a pump or CO2. Merely which should y'all use?

All of the normal considerations apply. CO2 is faster and a hell of a lot easier, but you're also express past the number of cartridges you conduct. A hand pump takes a lot of endeavour, but you can use it every bit many times as you want, you can't mess it upwards, and you can lend information technology out to people you lot meet on the trail without losing whatever flat-fixing capabilities.

But at that place's another factor to consider with tubeless tires: CO2 doesn't react well with latex-based tubeless sealant. Information technology causes the sealant to coagulate, making it much less effective. So you could be more likely to become flats through the residue of your ride.

That said, some people nonetheless use CO2 and merely swap out the sealant when they get home. They don't observe it to be a big deal at all.

Now that you know the pros and cons of each, you can make up one's mind for yourself.

Exist Prepared for Trailside Tubeless Tire Repairs

Tubeless tires are great for riders who hate fixing flats (which is, as far as I tin can tell, everybody). But at some point, you'll do more damage than your sealant can prepare.

The best advice I tin can give you is to be ready to repair your tires. Bring the correct equipment with y'all (namely a plug or 2, a tube, a boot, and a hand pump or CO2 inflator). The better prepared you are, the easier the process will be.
