5. Continue mounting the tire- check the

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 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. If the tire doesnʼt begin to seal after attempting

to inflate it, stop and reposition the bead of the tire with

your hands. Small changes in the position of the tire can

make a big difference.

7. Inflate the tire until the tire beads seat

onto the rim (Figure 5).

The beads often make an audible popping sound as they

snap into place. Use no more than 60PSI (4 ATM) to seat

the beads.

If the beads donʼt seat properly, deflate the tire and relubri-

cate the bead and rim surfaces by squirting the lubricant

through the gap between the tire and rim, and reinflate the

tire.

Make sure the beads are seated correctly in their locked

position before you use the wheel.

8. Thoroughly distribute the sealant

around the inner surface of the tire

(Figure 6).

Hold the axle tips in each hand and spin the wheel. Orient

the spinning wheel into a variety of positions (angles) so

that the sealant can reach the entire inner surface of the tire.

Some leaks in the casing can take time to seal, especially if

they are located near the bead area.

9. Adjust the tire pressure to the desired

value and install the wheel.

10. Verify that the casing has been

completely sealed

Ride the bike for a short time, and then check the tire

pressure. If the tire pressure drops too quickly, remove the

wheel and follow the Step #8 above to distribute the sealant
over the leak.
