Wheels & Tyres
What is a Tubeless Setup?
Running tyres without an inner tube, sealed instead with liquid latex.
Simplified schematic — not to scale.
In plain English
A tubeless setup does away with the inner tube entirely — the tyre seals directly onto the rim, with a splash of liquid sealant inside to plug small punctures automatically.
A simple analogy
“It's a self-healing tyre — like a car windscreen that patches its own stone chips as it drives.”
How it works
An airtight rim tape and tyre bead create a seal, while sealant sloshes around inside and instantly plugs any small holes as air tries to escape through them.
Signs of trouble
- ⚠Sealant weeping through the tyre sidewall
- ⚠Tyre slowly losing pressure over several days
- ⚠A hissing spray from a fresh puncture
Rough UK cost
