User manual BONTRAGER TUBELESS READY SYSTEM

[. . . ] It's especially important to pay attention to the installation instructions for tubeless tires if you've already mastered installing conventional tires; there are very important differences between the two. Pre-stretch the beads to make tire mounting easier The Kevlar bead of a new tubeless tire will stretch a substantial amount after it has been inflated initially. It's best to mount a new tubeless tire onto a standard rim before installing it on a tubeless rim- any wheel will do. Use an inner tube, inflate the tire to 60 psi (4 ATM) and leave it overnight. This will make it much easier to mount onto your tubeless rim. Use soapy water to mount tubeless tires With a tubeless or Tubeless Ready tire, the tire beads have to move along the surface of the rim and remain in contact with it during the inflation process. [. . . ] Lubricate the rim and tire beads with soapy water. Install the first tire bead onto the rim. Use your fingers to tighten the valve nut. Dont use pliers- if you puncture on the trail, you will have to be able to remove the nut by hand. 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. As in Step 3, start on the side opposite the valve. Position the second tire bead in the central channel of the rim and continue around the rim in both directions towards the valve area. When the bead becomes tight, complete the installation using one of the options below. 4. Start the installation of the second bead. Option 1 ­ Adding the sealant through the valve 1. Make sure that the beads fit properly on either side of the valve before adding the sealant. Loosen the inner portion of the valve with pliers and remove the core (Figure 2). Trim the tip of the plastic sealant bottle to fit the outer diameter of the valve core, or use a piece of plastic tubing that is a tight fit on both the core and the tip of the bottle to transport the sealant into the wheel. Carefully squeeze the proper amount of sealant into the wheel (Fig. Use a tire pump and push air through the valve to clear sealant out of the threaded area. Replace the valve core and tighten it gently in place with pliers. Figure 3- Adding Super Juice to the tire Option 2 ­ Adding the sealant before the tire is completely mounted Core Figure 2- Tubeless valve stem with removable core Work carefully to avoid spilling any sealant. Hold the wheel perpendicular to the ground and rotate the unmounted portion of the tire so that it is at the 6 o'clock position. Pull the unmounted bead away from the rim to create a gap, and squeeze the proper amount of sealant through the gap into the inner portion of the tire. Carefully rotate the wheel so that the unmounted portion of the bead is at the 12 o'clock position and finish mounting the second bead. 5 5. Continue mounting the tire- check the location and orientation of the tire beads in the rim (Figure 4). Tire beads 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 using a floor pump or compressed air source. If you are using a floor pump, it is usually necessary to initially inflate the tire with the fastest pumping motion possible. Once the tire starts to seal and hold air you can slow down. [. . . ] A large hole or fracture in the casing will weaken the tire. You should replace a severely damaged tire immediately, or as soon as possible. In an emergency a large patch, called a boot, can be made up of a fibrous material to cover the hole. The boot should overlap the hole by at least an inch in all directions and be bonded firmly to the casing. [. . . ]
