Self-Sealing Tyre

A self-sealing tyre has a sticky sealant layer inside the tread that closes small punctures so the tyre keeps its air.

What is Self-Sealing Tyre?

It typically seals tread punctures up to about 5 mm. The tyre looks and drives like a normal tyre. It does not protect against sidewall damage. Self-sealing tyres can be slightly heavier than normal tyres.

How it works

When a nail is pulled out, the sealant flows into the hole and plugs it.

Why it matters for your car

Have the tyre checked after a puncture even if it holds pressure. Tell the tyre fitter, as some repair methods differ.
