How To Change A Tubeless Mountain Bike Tire?

A tubeless mountain bike tire is a specialized type of tire designed for off-road cycling. Unlike traditional tires, it doesn’t require an inner tube. Instead, it forms an airtight seal with the rim, allowing riders to run lower tire pressures for better traction and reduced risk of punctures. Tubeless tires are popular among mountain bikers for their improved performance and durability on rough terrain.

Changing a tubeless mountain bike tire involves replacing or repairing the tire without an inner tube. It’s a useful skill for cyclists to handle punctures and maintain their tires. This process typically requires special tools and techniques to ensure a proper seal and reliable performance on off-road terrain.

Gathering Materials

Gathering Materials

Before you embark on changing a tubeless mountain bike tire, it’s essential to have the right tools and materials on hand. These include:

1. Tire Lever

  • A durable tire lever will make it easier to remove and install the tire on the rim.

2. Pump

  • A reliable pump, either a floor or a portable one, is essential for inflating the tire.

3. Replacement Tire

  • Make sure you have a suitable replacement tire that matches the terrain you’ll be riding on.

4. Sealant

  • Tubeless tire sealant helps seal small punctures and maintain tire pressure.

5. Valve Core Tool

  • This tool is useful for removing the valve core to add sealant or inflate the tire.


Preparation mountain bikes typically refer to the process of getting your mountain bike ready for a ride. This involves checking tire pressure, ensuring brakes are working, and inspecting the bike for any mechanical issues to ensure a safe and enjoyable biking experience.

Release Air Pressure:

Before you begin, release any air pressure in the tire by pressing the valve core to let the air escape. This step makes it easier to work with the tire.

Remove the Wheel:

To change the tire more comfortably, remove the wheel from the bike frame. This allows for better access and control during the process.

Removing the Old Tire

Changing a tubeless mountain bike tire starts with removing the old one. Here’s how to do it:

1. Use a Tire Lever:

  • Place the tire lever between the tire bead and the rim, ensuring it’s not pinching the tubeless tape.
  • Gently pry the tire lever upwards to unseat the flat tire bike bead from the rim. Be cautious not to damage the rim or tire.

2. Gently Work the Tire Off:

  • Once one side of the tire bead is unseated, work your way around the rim, gently pushing the tire off the rim.
  • Take care when removing the tire to avoid damaging it.

Inspect and Clean

After removing the old tire, it’s essential to inspect and clean the tire and rim:

1. Check the Inside of the Tire:

  • Examine the inside of the tire for any debris, thorns, or sharp objects that might have caused the flat. Remove any foreign objects.

2. Clean the Rim:

  • Wipe the rim clean to ensure there’s no dirt, residue, or sealant from the previous tire when learning how to fix a flat tire bike. A clean rim provides a better seal for the new tire.

3. Inspect Rim Tape:

  • While cleaning, check the condition of the rim tape. If it’s damaged or not covering the spoke holes properly, consider replacing it.

Installing the New Tire

With the old tire removed and everything cleaned and inspected, if you’re considering riding your mountain bike while pregnant, you’re ready to install the new tubeless mountain bike tire:

1. Place One Side of the Tire Onto the Rim:

  • Start by seating one side of the tire onto the rim. Ensure that the tire bead sits evenly within the rim.

2. Add Sealant If Needed:

  • If your tire requires sealant, add the recommended amount according to the manufacturer’s instructions. This sealant helps seal punctures as they occur while riding.

3. Align the Tire with the Valve Stem:

  • Align the tire so that the valve stem aligns with the hole in the rim. This ensures the valve stem is easily accessible when inflating the tire.

4. Push the Remaining Bead Onto the Rim:

  • With the valve stem aligned, gently push the remaining bead onto the rim. Ensure it’s even all the way around.

Inflating the Tire

Proper inflation is crucial for a tubeless tire. Here’s how to do it:

1. Use a Pump:

  • Use a suitable pump, whether it’s a floor pump or a portable one, to inflate the tire.
  • Ensure the pump has the necessary pressure gauge to monitor the tire’s inflation.

2. Check for Leaks and Sealant Distribution:

  • After inflating, inspect the tire for any visible leaks, as a bike tire won’t come off rim issue can be caused by leaks. You can do this by spraying soapy water onto the tire and looking for bubbles.
  • Roll the tire in different directions to distribute the sealant evenly, ensuring it covers any punctures.

Reattaching the Wheel

With the tire properly inflated, it’s time to reattach the wheel to your mountain bike:

1. Carefully Place the Wheel Back Onto the Bike Frame:

  • Ensure the wheel aligns with the frame’s dropouts and slides in smoothly. Don’t force it, as this can damage the axle or the frame.

2. Ensure It’s Securely Fastened:

  • Double-check that the quick-release or thru-axle is properly tightened to secure the wheel in place.

Final Check

Before hitting the trail or road, it’s essential to perform a final check to ensure your tubeless mountain bike tire is ready for action:

1. Test the Tire’s Pressure with a Gauge:

  • Use a pressure gauge to verify that the tire is at the recommended pressure. Adjust it as needed for your riding conditions.

2. Confirm There Are No Leaks or Issues:

  • Roll the bike and listen for any hissing sounds that might indicate a leak. Check the tire for any visible issues or deformities.

Frequently Asked Question (FAQS)
