Tubeless mountain bike tires offer several benefits like better traction, speed, and control on the trails. However, like any other bike tire, they need to be replaced once they wear out or get damaged. The process of replacing a tubeless mountain bike tire can be challenging, especially if you are new to biking.
In this article, we will guide you through the step-by-step process of replacing a tubeless mountain bike tire. We will also detail the tools you’ll need and offer some helpful tips to make the replacement process easier and more straightforward. Whether you are a seasoned rider or a newbie, this guide will help you replace your tubeless mountain bike tire like a pro.
Gather Needed Tools and Supplies
Before you dive into replacing your tubeless mountain bike tire, you must first gather all the necessary tools and supplies. The following equipment will be needed:
1. Tire lever or bead jack – These tools are used to remove the tire from the rim, making it easier to change the tube or inspect the tire.
2. New tire – Ensure that the tire size is compatible with your bike rim. You can also choose to replace both the front and rear tires for an even performance.
3. Sealant – You will need some tubeless sealant for your mountain bike tires. Always ensure that you measure the required amount of sealant in accordance with the manufacturer’s recommendation.
4. Compressor or Floor Pump – A compressor is preferable, but a floor pump can also work. Both should be capable of creating a good seal and delivering a high volume of air.
5. Scissors or trimmer – The sealant could leave a mess on the tire bead. Use scissors or trimmers to cut off any excess sealant.
It’s important to have all these tools and supplies ready before starting the replacement process. This will enable you to work effectively and quickly, without the need to run back and forth to the bicycle shop.

Remove the Old Tire and Rim Strip
To replace your tubeless mountain bike tire, the first step is to remove the old tire and rim strip. This may seem like a daunting task, but with the right tools and approach, it can be done easily.
First, you will need to release all the air from the tire and remove the valve core from the valve stem. Once you have done that, use a tire lever to unseat the tire bead from the rim. You can then pull the tire off the rim using your hands. Next, remove the rim strip by either pulling it off or using a screwdriver to pry it off. Be sure to inspect the rim for any damage or debris, and clean it thoroughly before installing the new tire. This step is crucial as any debris or damage to the rim can cause the new tire to fail or not seat properly.
Inspect and Prepare the Rim
Before installing a new tubeless mountain bike tire, it is crucial to inspect and prepare the rim to ensure that the tire stays securely sealed on the rim. Start by checking the rim for any signs of damage or wear, such as cracks or dents. If you notice any of these issues, it is best to replace the rim before installing a new tire.
Next, clean the rim thoroughly, removing any dirt or debris that may interfere with the sealing process. Use a rag and some isopropyl alcohol to clean the rim’s bead-locking surface. Be sure to also check the valve stem for any damage and make sure it is securely tightened in the rim. By taking these steps to inspect and prepare the rim, you’ll ensure that your tubeless tire stays securely in place while riding on rough terrain.

Install the New Tire Bead
Once you have successfully removed the old tire bead, it’s time to install the new one. Begin by inspecting the tire’s tread and sidewalls for any damage that may have occurred during the replacement process. If there are any signs of damage, don’t use the tire as it may lead to dangerous situations while riding on the tracks.
Next, position the new tire bead on the rim, starting from one side and following the rim’s circumference. Ensure that the bead is firmly seated in the rim’s center and is not twisted or crooked. Use your thumb and palm to push the tire’s bead along the rim, working your way around slowly. Ensure that the bead is evenly distributed on both sides of the rim. Once done, inflate the tire with the recommended pressure, and check its seating around the rim by pressing on it with your thumbs. Finally, double-check the tire’s pressure, and you’re ready to hit the trails with your freshly installed tubeless mountain bike tire.
Install the Tubeless Valve Stem
In order to install the tubeless valve stem, first remove the valve core from the stem to allow the air to flow freely. Then, thread the tubeless valve stem into the valve hole in the rim. Be sure to tighten it snugly and adjust the position so that the valve is perpendicular to the rim.
Next, insert the valve core back into the valve stem and tighten it with a valve core tool. This will create a seal and prevent any air from escaping. Finally, add sealant into the tire through the valve stem using a syringe or valve core remover tool. Once the sealant is added, inflate the tire to the recommended PSI and give it a spin to distribute the sealant evenly within the tire. By following these steps, your tubeless mountain bike tire should be good to go.
Add Sealant and Inflate
Once your new tire is in place, it’s time to add some sealant and inflate it. First, remove the valve core with a valve core remover tool. Shake your sealant bottle and pour the recommended amount into the tire. Replace the valve core and screw it back in using your tool. Now, it’s time to inflate the tire.
Attach your pump or CO2 inflator to the valve and begin pumping. Make sure to inflate the tire to the recommended pressure listed on the tire sidewall. As the tire inflates, spin it around to make sure the sealant is evenly distributed. You may need to “burp” the tire by deflating it slightly and then reinflating it to release any trapped air. Once your tire is at the right pressure and spins smoothly, hit the trails and enjoy your new ride!

Test and Fine-Tune the Tubeless Tire
After replacing a tubeless mountain bike tire, it’s important to test and fine-tune it to ensure that it’s properly sealed and inflated. The first step is to add sealant to the tire if necessary, to make sure that any punctures or leaks will be self-sealed. This can be done by removing the valve core and adding 1-2 ounces of sealant through the valve. After replacing the valve core, spin the wheel to distribute the sealant evenly inside the tire.
Next, check the tire pressure with a gauge and adjust it according to your preferences. A lower tire pressure can provide better traction and control on the trails, while a higher pressure can improve rolling efficiency. It’s a good idea to test the tire on a short ride to see how it feels and make any necessary adjustments. If you experience any air loss or leakage, check for loose valve cores, damaged rim tape, or other issues that might be causing the problem. By testing and fine-tuning your tubeless mountain bike tire, you can enjoy the benefits of a reliable and efficient setup on your next ride.
Final Words
To conclude, replacing a tubeless mountain bike tire is not a complex process but requires some practice. The key to success lies in having the right set of tools, following the steps carefully, and paying attention to every detail. It’s always wise to carry a spare tire and necessary equipment with you during your cycling trips, as any mishap can happen at any time.
In summary, with the method mentioned above, you can replace a tubeless mountain bike tire on your own quite efficiently. Regular maintenance of your bike’s tires does not only ensure your safety but also helps you improve your performance. Investing a little time and effort in understanding the process can save you from unnecessary expenses and keep you rolling on the trails for longer.
