Choosing Tubeless Mountain Bike Tires: What to Know

A tubeless mountain bike tire is an exciting new technology that allows you to ride with a lower tire pressure than ever before. Let's look at what makes them so special and how you can decide if they're right for you.

First of all, it's important to understand what a tubeless mountain bike tire is and how it works. Tires with tubeless technology do not need tubes to be inflated with air, as traditional tires do. Instead, they have a layer of sealant applied inside the tire that plugs up any punctures or holes in the casing as soon as they occur.

In situations such as hitting sharp rocks while riding on trails or being slashed by thorns while going through bushes, there will be no extra weight due to loss of air due to the sealant filling in any holes. It also means you won't have any flats either."

Tubeless tires provide better traction as they don't lose shape as easily as others over rough terrain or during hard turns like we've seen happen on some other websites by people trying not to stick their front wheel off into space when turning too sharply at high speeds. It just feels more secure."

Which type of mountain bike tire is right for you? That depends on a few factors, including your riding style, where you ride, and what type of terrain you ride on. Tires without inner tubes are becoming more popular since they are lighter and give better traction.

They're a type of tire that doesn't require an inner tube.

  • They're a type of tire that doesn't require an inner tube.
  • The term tubeless can be used to describe tires that do not have an inner tube as well as others. Instead, they rely on a liquid sealant and air pressure to keep them inflated. Also, the word 'tubeless' is used in other settings, such as with tubeless rims and tubeless valves, which are important components of the tubeless setup but not synonymous with it.
  • Tubeless tires have been around for many years, but you can now find more variety. At first, mainly mountain bikers used them. However, cyclocross and gravel grinders are discovering them too. They even come in some unusual tread patterns—ones you wouldn't normally see with traditional tube tires.

They're mostly used on mountain bikes, but more cyclocross and gravel-grinder riders are discovering them.

Tubeless tires are widely used on mountain bikes, but more riders use them for cyclocross and gravel grinding. Tubeless tires can operate at lower air pressures, increasing traction and reducing rolling resistance. They're also less susceptible to flats than comparable clincher tires with inner tubes.

Tubeless tires are more difficult to mount than clinchers because the bead must create an airtight seal against the rim. For reliable results, a compressor or CO2 inflator cartridge will likely be needed rather than a floor pump (more on that in a second).

They come in the same tread patterns as tires with tubes.

The size of your tire is measured in inches, but the width is measured in millimeters. For example, a 2.4-inch tire has a casing that measures 60mm from top to bottom. This measurement includes the bead (what the tire clings to on the rim) and the tread, with the rest being called "the casing."

The tire bead is designed to work with wider clincher rims, which must be tubeless-ready or tubeless-compatible.

It's important to note that your rim must be designed for tubeless tires before you purchase. A wide clincher rim (25–30mm internal width) is also needed for a tubeless tire because the tire's bead is designed to work with wider-rimmed options.

This wide rim helps support the tire bead and maintains an airtight seal more effectively than a narrow rim. Some companies offer clincher wheels to convert your rims that are not 'tubeless-ready' or 'tubeless-compatible.

Mounting them requires considerable force due to the tight fit between the bead and rim, and sealant can help seal around the spoke holes.

If you're going to inflate your tubeless tires, you can keep an eye on the pressure by using a floor pump with a gauge. Some people use air compressors, but that's not advised as they build up the pressure too quickly, which could blow out your tire or rim.

To help ease the bead onto the rim, put it in place and then spray water from a bottle onto the area between the rim and tire. This will lubricate the process, making it easier for the bead to slide into place.

Once one side is on, inflate it using the floor pump. The other side should pop into place as the inflator inflates and you should hear an audible "pop" as it inflates.

The tire may need to be inflated and deflated a couple of times before the bead locks into place, and this is normal.

You need to select compatible tires and rims and use rim strips. Some wheels come prepped with rim strips.

When choosing a tubeless tire, there are a few things to keep in mind.

  • First and foremost, your rim and tires need to be tubeless-compatible. Some rims are sold as tubeless-ready, meaning they were designed to work with tubeless tires. They have a soft rim bed for better tire seating (and lighter).
  • Tires and rims must match each other-check the label on the product page. The wheels & Kits section at the bottom of this page combines wheels and tires for a complete setup that works out of the box. If you want to mix it up, we suggest considering your current or future wheel when selecting new rubber, or vice-versa.
  • To tubeless-convert standard clincher wheels by adding sealant, ensure your rim's inner width matches your tire's width (found in our product descriptions). If not, you can run into issues such as burping or poor tire retention during cornering.
  • A rim strip covers spoke holes to create an airtight interface between the tube/tire and rim tape. Some wheels come with rim strips; otherwise, they're sold separately (though some newer wheels don't require them). You can reduce weight with natural cork strips, but go with tried-and-true red rubber strips instead if your budget is tight.

The valve stem must be long enough and sealed at the base to hold air pressure while removing the pump nozzle. A removable core allows you to add sealant.

As well as long enough valve stems that can reach through the rim hole and tire, they should be sealed at the rim base so you can remove the nozzle after pumping the tire. Removable core valves are required with sealant because they allow you to add more sealant.

Adding sealant through a removable core keeps it fresh longer than topping up when necessary. It also helps you spot leaks because it's messy when it shoots through a hole.

Depending on the brand and how often you ride, you'll need to add fresh sealant every three months.

By adding sealant through the removable core, your tires stay fresher longer, and you can spot leaks more easily while it shoots through holes. For those who aren't confident how to go about it, here are some tips:

  • Remove valve core with a 2mm hex key
  • Insert a syringe filled with sealant into the top of the valve and depress the plunger until the desired amount has squirted out
  • Replace valve core with a 2mm hex key

Tubeless bike tires are convenient, allow lower air pressures, and reduce flats, but mounting them is difficult.

Bike tires are a lot like those old tires you see in the back of cars: they're prone to pinching, and you have to be careful not to put too much air in them. It is recommended to use only 10 PSI with tubeless mountain bike tires, about one-third the maximum for inner tubes.

As well as improving cornering and braking, these lower pressures allow higher air pressures to be used on regular road tires, reducing tire weight and extending tire life.

This is more complicated than just filling up with less air and pressing a button. As a result, your wheels won't seal completely when inflated, potentially resulting in a pinch flat.

Or perhaps during high-speed cornering, your bike will suddenly slow down because there's too little air coming out of the valve stem. Either way, there are several things you can do to help make it easier for yourself if this does happen:

What are the benefits of using tubeless mountain bike tires?

We're not saying that tubes are bad, but if you can cut out the middleman and go tubeless, there are a few benefits to consider. Here's our quick list of the top five:

  • No pinch flats: Pinch flats result from the tube being pinched between the rim and the trail. Tubeless tires have nothing to pinch because there is no tube. Many riders also opt for tire inserts when using a tubeless system to protect their rims from impacts.
  • Tubeless setups allow you to ride at lower air pressures since pinch flats are not a concern. Better cornering grip, less rolling resistance on loose terrain, and more traction when climbing roots or rocks. Most riders can reduce their tire pressure by 5-8 psi (0.3-0.5 bar) with tubeless tires compared to traditional tires and tube setup. Mountain bike brake rotors and wheels are getting bigger, so check your wheel's manufacturer's recommendation for the minimum tire pressure for your style and weight distribution.

Types of tubeless mountain bike tires

Tubeless mountain bike tires come in various styles, just like standard tubed tire options. Cross-country tires will generally be lightweight and fast-rolling. Enduro and all-mountain tires offer more grip for rougher trails but can weigh more.

Downhill tires are designed to withstand the hard impacts of big hits and steep landings. Fat bike options are massive and designed for low pressures on snow.

If you are planning on riding tubeless, you will need to choose the type of tire specifically designed to be tubeless. If you want to go tubeless immediately, you may have a limited selection of tires if you decide on tires with thicker sidewalls or reinforced beads.

10 tips for choosing the right tubeless mountain bike tires

Here are some tips for choosing the right tubeless mountain bike tires:

  • Match your tire's width to your rim width. This will give you the best performance and is generally a good place to start.
  • The tread pattern, tread compound, weight, pressure range, durability, price, and brand are all considered. These qualities will vary from tire to tire, so finding one that fits your riding style is key.
  • Inflation is also important. You want a tire that inflates well without being too soft or stiff.

Are Tubeless Mountain Bike Tires Better?

Tubed tires have been around longer than tubeless ones, so they're not the end-all for mountain biking. In any case, tubeless tires are the best choice if you belong to any of these categories:

  • You're a cyclocross racer who wants a better grip and fewer pinch flats.
  • You ride a road bike on rough roads and want to improve your comfort and reduce punctures.
  • Are you a gravel grinder or endurance cyclist concerned about pinch flats damaging your rims?
  • You're looking for improved traction in slippery conditions such as mud or loose soil.

How to make it easier to fit tubeless mountain bike tires

To begin, though, you'll need to mount the tire and seal it. For this job, we recommend a soapy water solution and tire levers. Coat the inside of the tire with soapy water and mount it to the rim. Snap the bead into place on one side of the wheel first.

The tire can be inflated enough using a compressor or floor pump so that the second bead can be seated. Once both beads are secured, deflate the tire slightly and coat it liberally with a tubeless-specific sealant (we like Orange Seal).

Then inflate again—using either a compressor or a floor pump—to seat both beads on the rim properly. Check your work by looking at all areas of your wheels for daylight around your tires.

How to repair tubeless mountain bike tires

You'll need a tubeless tire repair kit to repair a puncture in your tubeless mountain bike tire. These kits are available at most bike shops and online.

Most come with rubber plugs to fill the puncture and an insertion tool to help you get the plug into the hole. If the tire is still attached to the rim, pry it away with a penknife or screwdriver to insert the plug.

Tubeless mountain bike tires provide better traction.

Tubeless MTBs have smooth rides and the ability to maintain grip in rough terrain. Bicycles are designed to keep the tire on top of the ground, not bounce off objects. Tires are inflated to maintain traction and absorb impacts, and the suspension absorbs bumps and keeps the bike upright.

Tubeless mountain bikes use less air than tubes, which means they can be ridden at lower pressures. A 175 lb rider could safely ride a 2.2" 29er tire at 20 psi instead of 35 psi.

With the lower pressure, technical climbs become easier and much more fun. Your tires absorb more of the power put into the climb.

Tire pressures are important when riding off-road. Either too little or too much pressure can lead to problems when riding. Common sense should be applied to avoid damaging your bike.

The Benefits of Going Tubeless

Tubeless tires are better than standard tires because they reduce air pressure inside the tire, making them safer by reducing the risk of blowouts. Tubeless tires also save money by eliminating the need for tubes.

Reduce weight from tires

Average 29er tires weigh around 200 grams. Tubeless setups use up to 125 grams of sealant per tire. This means that the overall weight savings can range from 150 - to 650 grams.

Shaving weight off your wheels will make them lighter and make them less stable. This means that you'll need to use different techniques to control your bike, and you won't be able to rely on your brakes as much, and you'll have to change your technique.

While the weight savings may seem minor, you'll notice it when powering up tough technical sections or trudging up climbs.

Eliminate Pinch Flats

Pinch flats happen when your tube gets pinched between the rim of your wheel and the tire. You'll need an extra tube if you're racing.

Pinch flats are caused when the tire isn't inflated enough. When the tire is inflated properly, there won't be any burping. A tubeless setup makes it easier to inflate tires.

Eliminate the Need for a Patch Kit

Many plants produce spines or needles. Some of them include Puncturevine, Mesquite Thorns, and Cacti. These plants are very dangerous because they have sharp points that can easily penetrate tires and puncture the tubes. You might not even notice these plants until your tire is already flat.

Tubeless tires are very useful because they don't need to be inflated, and small punctures won't affect them. Check your tire pressure regularly while riding your bike, and be sure to tighten the valve stem properly.

Tubeless tires are more reliable than tubes because if there is a problem, they won't explode. A tube could blow up in your face, but a tubeless tire wouldn't. Tubeless tires also last longer than tubes.

Deflating Some Myths

There will always be people who defend tube and try to argue that tubeless is not worth the effort. Tubeless is the lightest, most efficient, and most cost-effective set up in nearly every case.

Tubeless systems require regular maintenance. When riding in hot, dry conditions, the seals can dry up and cause problems. Ensure your tire pressure is correct and add small amounts of sealant on a regular basis.

Tubeless tires give you many advantages over traditional tires, and you get fewer flats, fewer maintenance issues, and much faster tire changes. Our staff can help you decide if tubeless is right for you. Call us today.

Mountain bike tires tubes vs. tubeless

Tubeless tires are designed to be used without an inner tube, making them more durable than traditional tubes because there is less risk of punctures.

However, this also means they won't inflate as easily as regular tubes. Tubeless tires are recommended for off-road riding or racing events when speed is important.

Tubeless tires are a great invention. They make your car safer and more efficient. You don't need to worry about punctures anymore. However, if you want to go tubeless, you should know how to install them.

There are many different ways to install tubeless tires. Some people prefer to use a conversion kit, while others prefer to buy ready-to-go tires. There are also some tips for installing tubeless tires.

How to tell if you can convert to tubeless mountain bike tires

Tubeless tires and wheels are now available as an option. You can check the outside edges of your tires to see if they say TLE or tubeless-ready. Loose rim tape means your wheels aren't ready for tubeless tires.

Tubeless tires are much easier to maintain than tubes, and Tubeless tires are also more durable because there is less chance of punctures. However, tubeless tires require additional tools to be installed correctly.

Advantages of tubeless mountain bike tires

A tubeless setup means you don't have to worry about flats because the sealant keeps the air inside the tube. Mountain bike tires are very thin, so the sealant helps prevent the tire from leaking air when a thorn gets stuck in them.

You don't need to worry about pinch punctures since there aren't any tubes to catch on anything.

Tire pressure is reduced to reduce the chance of pinch punctures, and this allows riders to use low-pressure tires without fear of pinch punctures. Riders can enjoy improved handling and riding qualities because of this change.

Disadvantages of tubeless mountain bike tires

Tubeless mountain biking is a lot more difficult than traditional tubed bikes. You need to install your tires properly if you want them to work correctly, and some people use sealants to ensure the tires stay inflated and seated properly.

Tires are more prone to punctures when they're off-road. You'd better carry spare tubes. Sealants are important because you lose them over time. Every few months, you should check your tires' condition.

How to make it easier to fit tubeless mountain bike tires

Tubeless tires are great because they're easy to install. You get your tire shaped before putting it on the wheel. Then you put the tire on the wheel without inflating it first, making it easier to remove the air from the tire after installation.

Many people use tubeless air tanks, and removing the valve core makes a huge difference. Pumping air into the tire quickly is done using a track pump.

Tubeless rims are great for riding on rough terrain. You can use them without needing to worry about sealing your tires. Tubeless rims are usually made out of aluminum or carbon fiber. Tubeless rims come in different sizes.

Some people prefer smaller-sized tubeless rims because they're easier to fit onto your bicycle. Tubeless rims work using a tube inside the rim instead of a normal tire. Tubeless rims allow you to ride over rocks and other obstacles without puncturing your tires. Tubeless rim tape is used to hold the inner tube in place.

Tubeless rims can be found in many different sizes. Some people choose larger-sized tubeless rims so they can carry more weight. Tubeless rims do require some maintenance.

Tubeless rims need to be cleaned regularly to prevent dirt from building up inside the rim. Dirt can cause problems when you want to get back on your bike after taking off.

How to repair tubeless mountain bike tires

Tire Bacon is a type of plug used to repair punctures in tires. You use an applicator to push them into the hole. Tires need to be inflated properly before using this product. This product works well when there is a lot of air pressure inside the tire.

You can stuff more than one thing into a puncture hole. But if that doesn't work, you'd better call a tow truck or rent a car. You could fix the hole from the outside of the tire at home using vulcanizing rubber solution, patches, and a tire boot. We've also used "mushroom" repairs to good effect.

Is it worth converting your mountain bike to tubeless?

Tubeless tires are much more popular than traditional tube tires, and they are cheaper and easier to maintain. Yet they are also less safe, as there is no air inside them, which means they are more susceptible to punctures.

Conclusion

is now in the bag, you know what tubeless mountain bike tires are and how they work. After reading this, we hope you're left with a better understanding of their pros and cons.

Tubeless mountain bike tires are convenient, allow lower air pressures, and reduce flats—but mounting them is difficult. If you want to give tubeless a try, here are two things that should help: 

1) get your local shop to install the first one; 

2) use sealant in both tires (or just buy one tube and use it as a backup). Once you're ready to repair on-trail, simply do what we showed above, repair the puncture and re-inflate using a floor pump or CO2 cartridge (or duct tape). Have fun out there.
