Tire removal and installation

The most critical factor of a tubeless tire is the seal between the wheel rim and the tire bead. For this reason, it is recommended to use a tire changer that can satisfy this sealing requirement and can make the operation efficient as well as functional.

1. 1
   Removal the wheel assembly. Refer to “front wheel assembly removal and installation” and “rear wheel assembly removal and installation” .
2. 2
   Remove the mounting drum from the rear wheel.

for operating procedures, refer to the instructions supplied by the tire changer manufacturer.

when removing the tire in case of repair or inspection, mark the tire with a chalk to indicate the tire position relative to the valve position. Even though the tire is refitted to the original position after repairing puncture, the tire may have to be balanced again since such a repair can cause imbalance.

Caution do not reuse the valve which has been once removed.

1. Apply tire lubricant to the tire bead.

never use oil, grease or gasoline on the tire bead in place of tire lubricant.

2. Install the tire onto the wheel.

for installation procedure of tire onto the wheel, follow the instructions given by the tire changer manufacturer.

• when installing the tire, the arrow “a” on the side wall should point to the direction of wheel rotation.
• Align the chalk mark put on the tire at the time of removal with the valve position.

1. 1
   Bounce the tire several times while rotating. This makes the tire bead expand outward to contact the wheel, thereby facilitating air inflation.
2. 2
   Install the valve core and inflate the tire.

• Do not inflate the tire to more than 400 kpa (4.0 Kgf/cm2, 57 psi). If inflated beyond this limit, the tire can burst and possibly cause injury. Do not stand directly over the tire while inflating.
• In the case of preset pressure air inflator, pay special care for the set pressure adjustment.

1. 1
   In this condition, check the “rim line” “b” cast on the tire side walls. The line must be equidistant from the wheel rim all around.
2. 2
   If the distance between the rim line and wheel rim varies, this indicates that the bead is not properly seated. If this is the case, deflate the tire completely and unseat the bead for both sides. Coat the bead with lubricant and fit the tire again.

   

1. 1
   When the bead has been fitted properly, adjust the pressure to specification.
2. 2
   As necessary, adjust the tire balance. Refer to “wheel balance check and adjustment” (page 2d- 17).

9. Install the mounting drum to the rear wheel.

(For rear wheel) refer to “rear wheel assembly removal and installation” .
