How do you install tubeless tires on a bicycle?


assistant
Tubeless tire installs require some setup. It's best to have experience with bicycle tires, and in particular, the use of tire levers to remove and install tires. Make sure your tires and rims are tubeless ready. If the manufacturer also provides a tubeless tape, use that, or use a generic brand. You'll also need sealant and a tubeless stem. The stem might require a tool to unscrew the nozzle for adding sealant. You'll also need a large syringe if you plan on using the stem to add sealant. You'll want a electronic pump, or a manual pump with a reservoir.

I have found that larger tires are easier to install as tubeless but road tires can also be tubeless. The first step is to clean the rim and install tubeless tape around the rim. This should seal the rim component. You'll need to punch a hole for the stem and insert the stem. Next you'll need to lever the tire onto the rim, first one side, then both. If you don't have a syringe, you can add some sealant at this step before fully installing the tire. For road tires, I've found this method prone to spilling.

Next, remove the core / nozzle from the tire stem and hook the stem up to your pump. You want to inject air into the tire quickly and at high pressure to "set" the beads of the tire against the rim. This should result in a popping sound. When you remove the pump, the tire will deflate since you removed the core. If you haven't already, add sealant at this step using a syringe, then reinstall the core and pump up the tire. I usually rotate the tire a bit, then flip it periodically while testing if it holds air. If it does you are done. Happy riding!
