Nothing ruins a great day of riding faster than a flat. Whether you are deep in the backcountry or just hitting your local singletrack, knowing how to change a tubeless bike tire is a critical skill for any cyclist.
You might be intimidated by the mess of sealant or the struggle of seating the bead. Don’t worry; with the right technique, it becomes a routine part of your maintenance rather than a roadside nightmare.
This guide breaks down the process into simple, actionable steps. We will cover the tools you need, the tricks to seat stubborn beads, and how to get back on the trail quickly and safely.
Understanding the tools for how to change a tubeless bike tire
Before you dive in, you need a specific set of tools. Having these ready will save you from frustration when you are out in the elements.
You will need a set of sturdy tire levers, a floor pump or a CO2 inflator, and a small bottle of fresh tire sealant. If you are doing this at home, a valve core tool is a game-changer.
Always carry a spare tube, just in case the tire sidewall is sliced beyond what the sealant can handle. A tubeless repair plug kit, often called “bacon strips,” is also essential for trailside fixes.
Step-by-step: How to change a tubeless bike tire
If your sealant has dried out or you have a major puncture, you need to remove the tire completely. Start by letting all the air out of the system.
Push the tire beads into the center channel of the rim. This is the narrowest part of the rim and gives you the extra slack needed to pry the tire off.
Use your tire levers to hook the bead and lift it over the rim wall. Work your way around the wheel until one side is completely free.
Removing the old tire and cleaning the rim
Once the first side is off, slide the tube out if you have one, or simply pull the rest of the tire off the rim. Inspect the interior for thorns, glass, or wire.
Take a moment to wipe away the old, crusty sealant from the rim bed. A clean surface ensures a proper airtight seal when you install the new tire.
Check your rim tape for any nicks or lifting edges. If the tape is damaged, your tire will never hold air, regardless of how much sealant you add.
Seating the bead for a perfect seal
Installing the new tire is the reverse of the removal process. Push one bead onto the rim, then feed the second bead on, starting opposite the valve.
Use your thumbs to work the bead into the center channel as you go. The last few inches are usually the tightest; keep the bead in the center to maintain that extra slack.
Before you add sealant, try to seat the tire using a high-volume pump or a compressor. If you hear a series of loud pops, that is the sound of the bead locking into the rim hook.
Adding sealant and finalizing the setup
Once the tire is seated, deflate it slightly and remove the valve core. Use a small injector or a nozzle bottle to pour the recommended amount of sealant directly into the valve.
Replace the valve core and pump the tire back up to your preferred pressure. Give the wheel a good shake to coat the entire interior of the tire with the liquid.
Spin the wheel and bounce it lightly on the ground. This helps the sealant find any tiny gaps or porous spots in the sidewall.
Frequently Asked Questions About how to change a tubeless bike tire
Can I reuse my old tire sealant?
Generally, no. Once sealant has been exposed to air and dried into rubber “boogers,” it loses its ability to plug holes. It is best to clean it out and add fresh sealant for the best protection.
What if I cannot get the tire to seat on the rim?
If the tire won’t inflate, ensure the bead is sitting in the center channel of the rim. You can also try using a soapy water solution around the bead to help it slide into place more easily.
How often should I refresh my tubeless sealant?
Depending on your climate and riding frequency, you should top off your sealant every 3 to 6 months. Hot, dry weather causes the liquid to evaporate much faster.
Is it safe to ride with a plug in my tire?
Yes, tubeless plugs are designed to be a permanent fix for most punctures. If the cut is larger than a few millimeters or is located on the sidewall, replace the tire as soon as possible for safety.
Final tips for trailside confidence
Mastering this skill takes practice, so do not wait until you are stranded to try it for the first time. Practice in your garage until you can swap a tire in under ten minutes.
If you ever find yourself in a situation where the tire won’t hold air despite your best efforts, do not hesitate to ask a fellow rider or a park ranger for assistance. Safety is always the priority.
Keep your gear maintained, carry the right supplies, and you will spend more time riding and less time fixing. Stay safe and enjoy the ride!
