tire manufacturer fi t, so some tires are more diffi cult to mount than others. Carefully follow the installation instructions, and you should be able to easily mount any tubeless tire. When mounting a tubeless tire, the tire must make an air- tight seal against the inner surface of the rim to allow initial infl ation. When riding, the bead must fi t the rim securely when the tire is mounted in order retain air, especially at low infl ation pressures. Because of these requirements, a tubel

Installation Removing a Bontrager Tubeless Ready or UST tubeless tire If the tire has sealant installed, be careful not to spill it as you remove the tire. It is best to remove the old sealant and replace it. If you have to reuse the sealant, carefully pour the pool of fl uid into a container. Scrape the sealant that remains on the casing into the container too. Rinse the rim and tire casing with water. 1. Deflate the tire. 2. Push the first bead into the center of the rim with your thumbs

1. If you have been using a tube, install the tubeless valve. Use your fingers to tighten the valve nut. Donʼt use pliers- if you puncture on the trail, you will have to be able to remove the nut by hand. 2. Lubricate the rim and tire beads with soapy water. 3. Install the first tire bead onto the rim. Start 180 degrees away from the valve and position the bead into the center channel of the rim. Push the bead over the rim, working your way to the portion near the valve. 4. Start the install

5. Continue mounting the tire- check the Tire beads location and orientation of the tire beads in the rim (Figure 4). The beads must fit uniformly into the central channel of the rim without twisting. The beads must straddle the valve where it projects through the rim strip, and make good contact with the rim strip surface in order to seal in that area. It is common to have to adjust the beads in the area around the valve before inflating the tire. 6. Start rapidly inflating the tire us

Troubleshooting Check the tire pressure on your bike before every ride; all tires lose air pressure due to air leaking through the inner tube or tire casing sidewall. Follow these troubleshooting steps in order to minimize the time it takes to repair a leaking tire. Causes of leaks If the rate at which air leaks from a tubeless tire is excessive, it can be reduced by repairing the source of the leak. Use Bontrager Super Juice tire sealant in any UST tubeless tire to reduce the rate of air

area around the valve seal or between the tire bead and rim strip. The leaking air can be detected at the spoke holes, but the location of the actual leak will not necessarily be close to the leaking spoke hole. There are two ways to fi nd and elimi- nate leaks like these: Partially immerse the wheel into a tub of water. Leave it in the tub long enough for the portion of the rim that is under- water to fi ll with water. Then, with your ear close to surface of the water listen for the sound
