Tires: Service and Repair

Tire Wear

1. Measure the tread depth of the tires.

Tread depth [limit] :1.6 mm (0.0630 in)

2. If the remaining tread depth (A) is less than the limit, replace the tire.

NOTE:
When the tread depth of the tires is less than 1.6 mm(0.063 in), the wear indicators (B) will appear.





Removal

CAUTION:
During all the operations on the tire, the sensor must be correctly maintained and thus it is FORBIDDEN to unscrew the nut and to force the sensor into the wheel. This could damage the sensor.

1. Take off the first side of the tire. The tool should not be used near the valve (no less than 30 cm).




2. Take off the second side of the tire. The tool should not be used near the valve (No less than 30 cm).




3. Dismount the first side of the tire: Place the shoe of the tool between 5 and 15 cm away from the sensor and use the tire lever as shown in the picture.




4. By using the tire lever, extract the external side wall of the tire and engage on the shoe of the machine. The lever and the tire must not come into contact with the sensor. Then remove the lever.




5. The wheel rotation allows the complete extraction of the first side of tire.




6. Raise the tire to prepare the introduction of the tire lever to aid extraction of the second side wall, the same recommendations as for the first side wall will apply.




7. By using the tire lever, extract the external side wall of the tire and engage the shoe of the machine. The lever and the tire must not come into contact with the sensor. Then remove the lever.




8. Extract entirely the second side wall of the tire.






Installation

CAUTION:
- Before any tire mounting operation, make sure that the sensor has been correctly mounted and tightened to the rim.
- No lubricant product or any other material may partially or completely cover the air pressure inlet hole of the sensor.
- The assembly tools have to never have a collision with the sensor.
- The tire cannot be in contact with the sensor only after it is engaged in the rim and after the exceeded peak of traction. Therefore, generally at the end of the assembly.

1. Prepare the tire and fix the rim as usual.




2. Put the tire on the rim, so that the cross point of the belt with the rim is between 15 and 20 cm away from the valve (see the picture).




3. Engage the shoe and make sure that 20cm is maintained between the cross point and the valve. The arrow shows the direction of rotation of the wheel.




4. Turn the wheel in order to engage all the first side of the tire.

NOTE:
The standard shoes can pass over the sensor without damaging it.




5. Put the second side of the tire in position, so that the cross point of the belt with the rim is approximately 20 cm away from the valve (see the picture). The curved arrow shows the direction of rotation of the wheel.




6. Turn the wheel in order to engage all of the second side of the tire.

NOTE:
The standard shoes can pass over the sensor without damaging it.




7. Perform the Register Sensor procedure.
