2. Adding an inner tube
Remove the tubeless tire
1. Let all the air out of the tire.
2. On tubeless compatible rims the bottom of the well is too narrow for both beads to rest fully against the rim bottom at the same time, so the tire must be placed to get one bead
down. With the wheel facing you (Fig. 4), roll the tire up and away from the rim with your thumbs while you use your fingers to tuck the opposite bead into the rim well Fig. 5).
3. At the valve, pull the lower, slacker bead of the tire up, out, and away from the rim (Fig. 6).
4. Pull the loosened bead up and out of the rim, rolling and pushing the tire toward the hub (Fig. 7) until the first bead is completely off the rim. Repeat to remove the other bead.
Note: If you choose to use tools to remove the tire, be careful not to mar the rim as this could reduce its ability to seal to the special beads of a tubeless tire.
Remove the valve stem
5. Remove the tubeless valve nut. Thread the presta nut into the valve stem, and push the stem out of the rim.
Install the tire and tube
6. Make sure the rim strip is centered in the rim well and fully covers all spoke holes. Install the tire and tube in the normal manner. With an inner tube, either a conventional
or tubeless tire can be used.
3. Changing to a tubeless tire
Remove the tire and inner tube.
1. Remove the tire by following item #2 Adding an Inner Tube, except start removing the tire opposite the valve.
2. Refer to item #1, Installing and Inflating a Tubeless Tire.
4. Removal and installation of a rim strip
Remove the rim strip
1. After removing the tire (and tube, or tubeless valve stem) insert a round-bladed screwdriver (or similar tool) through the valve hole, and between the
rim and rim strip (Fig 8). If the rim strip is to be used again, be careful not to tear or stretch the hole.
3. Lift the rim strip and place a tire lever underneath. Use the tire lever to lift and then roll the rim strip over the opposite rim hook (Fig. 9). Be careful
not to mar or damage the rim, or rim strip, with the tire lever.
4. Continue to roll the rim strip up and out of the rim as you work your way fully around the rim.
Install the rim strip
1. Make sure the rim strip is in good condition, with no tears, holes, or deformed areas near the valve hole or
along its edges.
2. Align the rim valve hole and rim strip valve hole. Place the special tubeless valve (or a similar item) through
the rim strip valve hole, and then the rim. The 'U' shape of the rim strip should face the same direction as the 'U'
shape of the rim well (Fig. 10).
3. Work the rim strip into the rim, moving away from the valve stem in both directions. With six to ten inches (15
to 25 cm) rim strip remaining outside the rim, manually lift and slightly stretch the rim strip so that it can be laid
flat in the rim well.
4. Follow the appropriate installation procedures to install a tire.
