Tyres > Help > Tyres Help > Is a plug or a patch better for a puncture?
A plug is a rubber strip pushed into the puncture hole from the outside, without removing the tyre from the wheel. A patch is fitted from the inside, once the tyre has been removed, and is bonded directly onto the tyre's inner liner.
Not on its own. A plug seals the hole itself, but it doesn't address the inner liner, the layer that actually holds the tyre's air pressure, and it doesn't allow the inside of the tyre to be inspected for hidden damage. A plug-only repair isn't compliant with the BS AU 159 standard, so it's best treated as a temporary get-you-home fix rather than a permanent one.
A professional repair combines a plug and a patch in one unit, often called a mushroom or combination repair. The tyre is removed from the wheel, checked internally for any damage that isn't visible from the outside, and the combination repair is fitted through the puncture and bonded to the inner liner.
A combination plug-and-patch repair carried out by a professional is the better long-term option, since it's fully inspected and properly seals the inner liner. A plug or sealant kit is fine to get you moving in an emergency, such as with a tyre repair kit at the roadside, but you should still get the tyre properly repaired or replaced afterwards.
