How to set up tubeless tyres

Insert the tubeless valve into the wheel through the valve hole. Place any washers and the lock nut over the valve, then tighten the nut to secure the valve in place. Crucially, don't over-tighten here otherwise you’ll struggle to loosen the nut in the future. Finger tight is enough.

Fit one side of the tyre onto the wheel. Once it’s on, push the tyre bead into the centre of the wheel. This will make it easier to fit the other side of the tyre.

Start fitting the other side of the tyre, but don’t fit all of it. Instead, leave around 15 centimetres of the tyre off of the wheel. It will be easier if this section of tyre is also near the valve.

Give the bottle of sealant a shake, then rotate the wheel so that the open section where the tyre isn’t fitted is at the bottom. Carefully insert the sealant into this gap.

With the sealant inserted, rotate the wheel so that the open section is at the top. Push the remaining section of tyre onto the rim with your thumbs, although you can use tyre levers too if you have any difficulty. This part is usually a little messy, so it’s worth having a cloth ready to wipe away any sealant which escapes.

Now that the tyre is fully fitted to the wheel, it’s time to inflate it. A track pump will usually be required for this, although a smaller pump may sometimes work.

Pump the tyre up to the recommended limit. As the tyre starts to seat, some sealant may escape but don’t worry about this, it can be wiped away. Once it’s inflated to the maximum recommended pressure, carefully go around both sides of the tyre, making sure it is securely seated on the rim.

Your tubeless tyre should now be set up and ready to go. Check they're seated properly on the rims, with no warps or bulges.

Once you’ve fitted both of the tyres, put the wheels back on your bike and then go for a short ride up the road and back, just to spread the sealant around the tyres.
