How to Mount a Tubeless Tire

How to Mount a Tubeless Tire
Many mountain bikes today employ tubeless tires. The design relies on a rim with a unique internal shape and a tire with a butyl rubber liner molded into the casing. The design eliminates the need for an inner tube, making for a lighter tire and one that is less susceptible to so-called pinch flats, which happens when an inner-tube becomes pinched between the tire and rim, causing a puncture. Anyone who has mounted a tube-type bicycle tire before will recognize many of the steps involved in mounting a tubeless tire.
 

Instructions

Difficulty: Easy

Things You’ll Need:
  • 1/2 tsp. dish soap and 32 oz. water solution
  • Spray bottle (or clean rag)
  • Bicycle tire lever (as needed)
 
Step 1
Spray the inside of the rim with a soap and water combination. The solution should be about 1/2 tsp. of dish soap and 32 oz. of water. A spray bottle works best, but the solution can also be applied using a clean rag or towel.
Step 2
Match the tire label with the valve stem, and mount the first bead onto the rim. A tire has two beads, each one running along the bottom circumference of the tire.
Step 3
Mount the second bead into the rim. Be sure to push the bead into the center, or deepest part, of the rim.
Step 4
Push the last section of the bead into the rim. This will be the hardest portion. Use the flat end of a plastic tire lever if necessary, but careful not to damage the liner on the inside of the tire.
Step 5
Turn the wheel to check that both beads are nestled in the center of the rim.
Step 6
Pump the tire to about 20 PSI (pounds per square inch) or enough air whereby the beads form a loose seal against the rim. Add more air until the beads are firmly seated. The beads will "pop" as they press into the place, forming a seal against the rim.
Step 7
Inspect the sidewalls to ensure that the tire is seated uniformly. The tire is fully inflated when the bead-seat indicator (a raised ring that extends just above the rim wall) is equally exposed around the diameter of both sides of the tire.
