What you need
| Part | Why |
|---|---|
| Tubeless-ready rims | Shaped to lock the tyre bead in place |
| Tubeless rim tape | Seals the spoke holes. Pick a width just wider than the rim's internal width |
| Tubeless valves | Match the valve length to your rim depth |
| Tubeless-ready tyres | Marked TLR, TLE, TL-Ready or similar |
| Sealant | Fills small holes as you ride |
| Track pump or booster | A quick burst of air seats the bead |
How to set up
- Clean the rim and remove the old tape if it's damaged.
- Tape the rim, starting a little past the valve hole and overlapping by about 10cm. Pull it tight and press it flat.
- Fit the valve and tighten the lockring by hand.
- Fit the tyre, starting opposite the valve. Soapy water on the bead helps it seat.
- Inflate fast with a booster or track pump until you hear the beads pop into place. Don't go above the rim or tyre maximum.
- Add sealant through the valve (core removed) or before fitting the last part of the bead.
- Spin and shake the wheel so the sealant coats the inside, then leave it on its side for a few minutes, then the other side.
How much sealant?
| Bike | Per tyre (typical) |
|---|---|
| Road | 30–40ml |
| Gravel | 40–60ml |
| MTB | 60–100ml |
Follow your sealant maker's guide. Top up every 2–6 months, sooner in hot weather.
When sealant isn't enough
For bigger holes, use a tubeless plug from the outside. Always carry a spare tube and tyre levers too, in case the tyre won't seal.
FAQs
Can I make any tyre tubeless?
No. Use tyres marked tubeless-ready, especially on hookless rims.
Why won't my tyre seat?
Check the tape, use soapy water, remove the valve core for more airflow, or use a booster pump.
Does sealant dry out?
Yes. If you can't hear it sloshing, it's time to top it up.
