Fixing of flat tubeless tyre

Tubeless tyres offer several advantages, however in the event that you experience a puncture the repair is somewhat more complex than with wired-ons.

Removal of the tubeless tyre

1. Remove the wheel.

2. Completely deflate the tyre. Now push the bead on one side of the tyre into the bed of the rim. Now remove the bead you have just pushed inwards by pulling it up over the edge of the rim with your fingers. Now the tyre should be hanging over the edge of the rim on one side. Now you should be able to gently pull the tyre fully off the rim.

3. Now you should be able to gently pull the tyre fully off the rim.

Repairing a punctured tubeless tyre

1. In the event of a puncture tubeless tyres can also be ridden with an inner-tube. First remove the foreign body from the tyre before inserting an inner-tube.

2. Also remove the valve from the rim. Insert a slightly inflated MTB inner-tube inside the tyre. Now fit the tyre as described in the instructions for fitting wired-on tyres and ensure that the tyre is fitted correctly on the rim and inflated to the correct pressure.

3. Tubeless tyres can be sealed/repaired using a standard repair set. Please follow the instructions of the repair kit manufacturer.

Fitting tubeless tyres

1. Before fitting check that the inside of the tyre is free from foreign bodies and the bead, rim and valve are clean.

2. Moisten the tyre bead on both sides before fitting with soapy water or tyre assembly paste. Do not use tyre levers to do this. Only use your hands to force the tyre onto the rim so as to avoid damaging the tyre bead and rim.

3. First press one bead across the entire circumference of the tyre over the flange of the rim. Then press the bead on the other side of the tyre over the flange of the rim.

4. Now centre the tyre on the rim, ensuring that the tyre is sitting correctly in the rim bed and the valve and the valve is straight. Inflate the tyre to its maximum permitted pressure. The maximum permitted pressure is normally printed on the wall of the tyre.

5. The tyre should now be seated correctly in the rim bed. The rim line must be parallel to the rim flange all the way around the tyre. Adjust the inflation pressure to your requirements taking into consideration the pressure markings on the tire and the manufacturer’s recommendations.

Fitting the wheel

1. Ensure when fitting the wheel that it is perfectly centered between either the fork blades or chain stays.

2. Mount the wheel.

3. Close the quick release.
