How to Setup Tubeless Tires

Go Tubeless for Road Cycling or Mountain Biking

Tubeless systems have been around a few years for mountain bikes with obvious benefits. Without inner tubes, there is no need to worry about dreaded pinch flats which occur when the tube is pinched between the ground and the rim. And, without worrying about pinch flats, you can run much lower tire pressure which means better traction. Not to mention, if you do get a thorn in your tire or a small tear from an encounter with a rock, the sealant inside your tire can save you from getting a flat.

Now that tubeless has entered the world of road cycling, what are the benefits?

So, what are you waiting for? Ready to go tubeless?

What You’ll Need

Tubeless Tire Setup

1. Ensure your tires and rims are tubeless-ready. Don’t worry, it should say so right on the label! 

2. Remove your wheel from your bike.

3. Remove the tire and tubes from the rim. Check out our Fix-a-Flat guide for tips on removing your wheel, tires, and tubes.

4. If your rim is wrapped with a plastic rim strip that is not tubeless compatible, remove the rim strip.

5. Tape rim using tubeless-specific rim tape.

6. Using a metal pick or a small Phillip’s head screwdriver, poke a hole where the valve stem will be inserted. Be careful not to make this hole too big.

7. Insert tubeless valve stem into the valve hole and secure using plastic O-ring and washer provided.

8. Put the tire on the rim. If the tire is directional, make sure it is on correctly. Get more tips on how to change a tire by checking out our Fix-A-Flat Guide.

9. Insert recommended amount of tubeless sealant into the tire. There are two different ways of doing this:

10. After the tire is mounted completely onto the rim with sealant inside, roll the tire on the ground to disperse the sealant. Pull the bead of the tire to the edge of the rim, if possible.

11. Inflate the tire! The best way to get the tire to seal is to add air as quickly as possible. That is why using an air compressor is the best method. If you do not have access to an air compressor, use a charger pump, like the Giant Control Tank Tubeless Inflator.

PRO TIP: Are you using an air compressor or tubeless inflator system and still having trouble getting your tire to inflate? Try removing the valve core on your tubeless valve. This will allow air to enter your tire even faster than it would through the valve. Just be careful once you remove the inflator nozzle from the valve since all the air will rush back out of the tire! Be ready with your finger to hold the air in and quickly replace the valve core with your tool.

12. After the tire is inflated and the bead is seated, bounce the tire on the ground. This will help disperse the sealant inside of the tire.

13. Replace your wheel and take your bike for a spin. Riding your bike right after setting the tires up tubeless will ensure a good seal.

14. You did it!

*If your tires are already set up tubeless and you are just changing to new tires, disregard steps 5-7. Remove any old sealant with an absorbent cloth and check your rim tape for damage before putting the new tire on.

*Over time, the sealant inside your tires will dry up and stop protecting you from pesky flats. Hot/ dry climates will cause the sealant to dry up faster. Check your sealant levels by shaking the wheel while it is off the bike. You should be able to hear the sealant sloshing around inside. If you can’t hear anything, you need to add more sealant! Otherwise, check your levels/ top off your sealant every 30 days.
