Bontrager WHEEL - Installing a Traditional Tire and Tube

20 21
Do not over-inflate. Overinflation may damage the rim. Do not exceed the
maximum inflation rate of 120 psi (8,3 atm) on carbon road rims.
8. Inflate the tire to 20-30 psi (1.5-2 atm).
9. Check the inner tube. Push in the sidewall of the tire slightly and make sure the inner tube is
not pinched between the rim hook and the tire bead. Continue all the way around the rim,
on both sides.
10. Check for correct tire bead engagement in the rim (Figure 18 and 19). Most tires have a
mold line near the bead of the tire where it engages the rim. All the way around the rim, the
distance between the mold line and the top edge of the rim must be even and equal. If the
distance is not equal, deflate the tire and repeat this procedure.
11. Inflate the tire to the pressure indicated on the side of the tire. Do not exceed the maxi-
mum inflation rate of 120 psi (8,3 ATM) on carbon road clincher rims and 60 psi (4,1ATM) on
carbon mountain clincher rims.
12. Check for correct tire bead engagement again.
Figure 18. Correct. Make sure the mold line of
the tire is equal (X distance) with the
rim all the way around.
Figure 19. Incorrect. The mold line of the tire is
not equal all the way around.

WARNING
1. Inflate the inner tube until it begins to take shape.
2. Place the inner tube in the tire.
3. Insert the valve stem through the hole in the rim.
4. Install the first bead onto the rim (Figure 14). Start at the valve stem.
5. Push the tire and inner tube over until the inner tube is inside the rim (Figure 15).
6. Push the second bead into the rim. Start at the valve stem. Be careful not to pinch the inner
tube between the rim and the tire (Figure 16) when you install the tire.
7. Push the base of the valve stem up into the tire so that it is not caught between a tire bead
and the rim (Figure 17).
Installing a Traditional Tire and Tube
The following steps are necessary for proper installation of a traditional tire and tube on a
Bontrager clincher wheel.
A traditional rim strip will need to be installed prior to proceeding with these steps.
Figure 14. Place the first tire bead in the rim.
Figure 15. Push the first bead to the side and
insert the inner tube.
Figure 16. Do not pinch the inner tube
between the tire and the rim.
Figure 17. Make sure the inner tube is not
caught under the tire beads.
