How do Tubeless Mountain Bike Tires Work? Everything you Need to Know

Tubeless tires work by ditching the inner tube that tubed tires have. This allows tubeless tires to reduce weight, provide greater performance, and improve sturdiness to punctures.

This page is a straightforward solution for anyone keen to know how tubeless tires work, wishing to go tubeless, or wondering which kind of tire to choose and contains all the necessary information.

How do Tubeless Tires Work?

The tires work in the way they are named. Tubeless tires use compressed air to create a seal between the wheel rims and the tires. Simply put, the spoke holes of the rim are covered with some tubeless rim tape, the air is captured using a valve stem, and the compressed air is sealed airtight with a sealant product.

This has various advantages, starting with an improved grip and higher puncture resistance. If you’re considering upgrading to a tubeless configuration, you’ve probably heard the term ‘tubeless ready.’ 

Tubeless Ready (also abbreviated TR or TC) refers to components that have been engineered to perform with or without a tube.

Tubeless Tires: Benefits and Drawbacks

Like everything in this world, Tubeless tires also have advantages and disadvantages, but in most cases, the pros overpower the cons by a long shot.

Advantages:

Tubeless tires enable you to get the highest performance out of your setup. Tubeless tires are less prone to puncture as they have a higher resistance than tubed ones as they have no tubes in between the rims and tires, which can also save you from a few snakebites.

You can use lower pressures on tubeless tires, which allows for more comfort and improved grip. A sealant can also immediately take care of any flats that do occur and reduce rolling resistance.

The tires can also maneuver better around obstacles, letting them roll and deflect stones easily due to lower pressures. It also may be cheaper to use for the long-term

The advantages summarized:

  • Improved resistance
  • Allows to run at lower pressure
  • Better grip
  • Provides more traction
  • Self-Sealing
  • Cheaper in the long run,
  • Better maneuverability

Disadvantages: 

The biggest disadvantage of going tubeless is the greater difficulty setting up and, later on, servicing. The initial cost of components is not too high, but the total will be much more if tubeless-ready wheels and tires are not there.

A specific tubeless inflator pump or compressor will be required to install some tire and rim types. Similarly, the setup also needs to be serviced regularly. Not doing so will cause inefficient performance and affect sealing.

Tubeless tires might also leak a bit of air during every ride, so it is important to check pressure every time.

Disadvantages summarized:

  • The initial cost can be expensive
  • Needs to be serviced often
  • Tubes are easier to install
  • Pressure loss during rides
  • Tire “burping”
  • Sealants can coagulate in a matter of months
  • Valves can coagulate too

What Pressure to use on Tubeless Tires

A tubeless system means you can use your tires at lower pressures, as opposed to tubed systems, without sacrificing sturdiness and puncture resistance. As mentioned earlier, this is possible because of the absence of the tube in the tire, which could be squeezed in between the rim and obstacles.

Lower pressures will give you higher performance, more comfort, and improved grip out of your system. You will need to experiment with different tubeless tire pressure settings until you find the best combination.

It is essential to remember that although you might require a specialized tubeless inflator pump for the first setup, you can use any conventional pump for the routine pressure check or topping up the tire after it has been inflated.

Should you Buy Tubeless Tires?

Yes, you should buy tubeless tires as they are more recent and advanced technology. A tubed system might be quicker to set up and takes little maintenance if you use your bike sometimes. 

However, we strongly suggest going tubeless for anyone who regularly rides their mountain bike off-road. Tubeless tires provide maximum performance, improved grip, and comfort

How to fix a Tubeless Tire Puncture or Flat

Mountain bikers often ask, “How do I fix my tubeless tire puncture?” This is a very common problem; therefore, in this section, we will learn how to fix a puncture.

Despite being sturdy and less prone to punctures than tubed ones, it is not perfect and unseen problems can happen during rides. One of the most frequent problems is a puncture in a tread or sidewall, mostly caused by a sharp rock or thorn that might be too large to be fixed by a sealant alone.

Tire plugs are a quick and easy solution for these. Tire “burping”, as mentioned earlier, is another problem. This occurs when the tire is moved across the rim in a strong compression, temporarily pushing the beads away from the rim flange and allowing air to escape before sealing again.

If your tire has “burped,” you need to re-inflate it to the pressure you want it to be at. It is far more difficult to repair large tears in the sidewall and air loss caused by damage to the rim. We suggest you solve the issue at your residence by installing a tube.

Conclusion

The advent of Tubeless tire technology in mountain biking has been a game changer. These tires now allow us to reduce weight, enjoy higher sturdiness to punctures and flat hitting, and of course, allow greater performance.

Tubed tires are old technology and take up more weight which is a hassle for a rider. Tubeless technology will improve even further and provide more advantages in the future.
