racked. The reason for the tyre bead to the wheel rim contact is to support the edges of the tyre once inflated and to stop tyre rotation. Some wheels are fitted with a rim lock to stop tyre rotation and enabling their tyres to be run at lower pressures as the rim lock acts as a clamp between tyre and rim. So we must break the bead of the tyre. In some cases the tyre will easily dislodge itself from the rim when you apply pressure to the sidewall of the tyre with the wheel laying flat on the ground. A good way to do this is using your heel of your boot/shoe to apply the pressure. If the bead won’t dislodge another technique if you do not carry a beadbraker tool is to use you bikes weight to do this for you. Place the sidestand onto the wall of the tyre close to the rim and transfer the bikes weight through the sidestand onto the tyre to break the bead. Refer picture 1. Again be careful that you do not bend your disc and put a rag or similar on the ground to keep your exposed wheel bearings free of dirt. Once the bead is broken on one side you will need to turn the wheel over to do the same on the other side. The tyre bead is broken to allow the tyre extra movement on the rim which will aid in removing the tyre from the rim with your tyre levers.
Make sure the tyre is off the rim all the way around on both sides. Next you will insert a tyre lever between the tyre wall and the rim and proceed to lever off the tyre from the rim on one side. You will need to use two or more levers to perform this task,
Next the valve is put back into the tube and the tyre is inflated so that the tyre beads (2) seat themselves onto the rim. Not recommended to inflate anymore than 70 psi. You should check that the tyre is seated correctly once inflated. Check around the perimeter of the tyre on both sides for an even fit. There is usually a line around the tyre wall by the rim which will help with checking alignment. The slippery product that was applied when putting the tyre on the rim will aid in the tyre seating itself correctly to the rim. When inflating the tyre it is not uncommon for the tyre to pop into place with the pressure. When satisfied that the tyre is seated correctly your air pressure can be returned to the desired/manufacturers pressure. Refer picture 9.

To fix punctures carry spare tubes and a puncture repair kit or plugs for tubeless tyres. Refer manufacturer's insturctions for the use of these products.
Rim protectors if desired to protect your rims/paintwork from damage.
Happy tyre changing. It is really satisfying being able to change your own tyres not to mention vital for your motorcycling journey should you get a puncture.
Our standard gravel road rides will be mixed over the "Summer"?? with a good variety of New Adventures that will take us "OVERLAND" and beyond into "New Areas" that NGARNZ has not previously ridden as a Group before. We plan to make the very most of our NEW OVERLAND Adventures". Our Summer season really is a very short one.
Expect the unexpected as we continue to look to surprise and showcase to our two-wheeled Adventure Riders a little more of our country than we would normally see.
