Tire removal

The most critical factor of a tubeless tire is the seal between the wheel rim and the tire bead. Because of this, we recommend using a tire changer which is also more efficient than tire levers.

For tire removal the following tools are required.

NOTE:

Mark the tire with chalk to note the position CD of the tire on the rim and rotational direction ® of the tire.

• Place the center shaft CD to the wheel, and fix the wheel

with the rim holder ®. CD

• Attach the operation arm ® to the center shaft. ®

• Attach the bead breaker © to the operation arm, and remove the bead from the rim. Turn the wheel over and remove the other bead from the rim.

•

• Install the rim protector ®, and raise the tire bead with the tire lever (J).

WHEEL

Wipe off any rubber substance or rust from the wheel, and inspect the wheel rim. If any one of the following items is observed, replace it with a new wheel.

* A distortion or crack.

* Any scratches or flaws in the bead seating area.

* Wheel runout (Axial & Radial) of more than 2.0 mm (0.08 in).

TIRE

Thoroughly inspect the removed tire, and if any one of the following items is observed, do not repair the tire. Replace with a new one.

* A puncture or a split whose total length or diameter exceeds 6.0 mm (0.24 in).

* A scratch or split at the side wall.

* Tread depth less than 1.6 mm (0.06 in) in the front tire and less than 2.0 mm (0.08 in) in the rear tire.

* Ply separation.

* Tread separation.

* Tread wear is extraordinarily deformed or distributed around the tire.

* Scratches at the bead.

* Cord is cut.

* Damage from skidding (flat spots).

* Abnormality in the inner liner.

NOTE:

When repairing a flat tire, follow the repair instructions and use only recommended repairing materials.

Inspect the valve after the tire is removed from the rim, and replace with a new valve if the seal rubber has any splits or scratches.

Inspect the removed valve core and replace with the new one if the seal rubber is abnormally deformed or worn.

Any dust or rust around the valve hole must be cleaned off. Then install the valve in the rim.

CAUTION:

When installing the valve, tighten the nut CD by hand as much as possible. Holding the nut CD under this condition, tighten

the lock nut ®· Do not overtighten the nut CD as this may distort the rubber packing and cause an air leak.

• Apply a special tire lubricant or neutral soapy liquid to the tire bead.

CAUTION:

Never apply grease, oil or gasoline to the tire bead.

•

•

• Rotate the operation arm around the rim to mount the bead completely. Do the bottom bead first, then the upper bead.

• Remove the wheel from the tire changer, and install the valve core in the valve stem.

NOTE:

Before installing the valve core, inspect the core.

• Bounce the tire several times while rotating. This makes the tire bead expand outwards, and thus makes inflation easier.

NOTE:

Before inflating, confirm that the balance mark lines up with

the valve stem. t

•

Do not inflate the tire to more than400kPa(4.0 kg/cm2, 56 psi). The tire could burst with sufficient force to cause se­ vere injury. Never stand directly over the tire while inflating it.

NOTE:

Check the " rim line" cast on the tire side walls. It must be equidistant from the wheel rim all the way around. If the dis­ tance between the rim line and wheel rim varies, this indi­ cates that the bead is not properly seated. If this is so, deflate the tire completely, and unseat the bead for both sides. Coat the bead with lubricant, and try again.

• After tire is properly seated to the wheel rim, adjust the air-pressure to the recommended pressure. Correct the wheel balance if necessary.

WARNING:

* Do not run a repaired tire more than 50 km/h (30 mph) with­ in 24 hours after tire repairing, since the patch may not be completely cured.

* Do not exceed 130 km/h (80 mph) with a repaired tire.
