What do I need to convert my wheels and tires to tubeless?

By Crankworthy · Published · Updated

Short answer

Tubeless-ready rims (or rims sealed with tubeless tape), tubeless-ready tyres, a tubeless valve for each wheel, and sealant — plus enough air, fast, to seat the tyre beads. Most kits bundle the tape, valves and sealant.

Schematic. The tape is the part you replace when converting a tubeless-ready rim; sealant dries out and needs topping up. Steps follow Park Tool’s tubeless conversion guide.

What each part does

The rim has to hold air on its own. Tubeless-ready rims have a bead shape designed to lock the tyre in place; the spoke holes are covered with airtight tubeless tape, which is the part you replace when converting.

Tape width matters: tape that is too narrow will not seal, and tape so wide it runs up into the bead seat can spoil the seal [1].

The tyre has to be tubeless-ready too — ideally both tyre and rim are designated tubeless ready [1]. Its bead and casing are made to seal against the rim; a standard tyre is not, and will leak or burp air.

A tubeless valve replaces the tube's valve and seals against the rim bed. Sealant sits inside the tyre and plugs small punctures and any gaps at the bead as you ride. It dries out over time, so it needs topping up every few months.

Seating the bead usually needs a sudden rush of air. A track pump sometimes manages it; a tubeless inflator or compressor makes it much easier. Even then, a full seal can take time — sometimes days — so do not plan to ride straight away [1].

Check your wheels first

Rims
Look for "tubeless ready" or "TLR" printed on the rim or in the wheel's spec.
Tyres
Look for markings such as "TR", "TLR", "TLE" or "Tubeless Ready" on the sidewall.

Don’t buy: a standard tyre for a tubeless setup
Instead: one marked tubeless ready.
Don’t buy: rim tape in a width that does not match your rim
Instead: tape sized to your rim’s internal width.
