Universal EURO Tire Patch 38 mm – Radial and Diagonal, Xtra Seal
Tire repair patch | EURO type, universal | Brand: Xtra Seal | Sold as: 1 pc.
The Universal EURO patch 38 mm from Xtra Seal is a round patch for nail puncture repairs in both radial and diagonal tires. Unlike dedicated radial repair inserts, this patch is built for both tire constructions — hence the "universal" designation. It can be used on its own or alongside a STEM repair plug, which allows a complete nail puncture repair (sealing the puncture channel and reinforcing the inner liner) to be done with a single combination. The slit mylar backing is peeled off right before mounting. It works with cold and hot vulcanization.
Product Overview – Universal EURO Patch 38 mm 11-307
The patch consists of black rubber over a blue tie gum, which creates a durable bond with the inner liner surface once cured. Thin, even edges lower the risk of the patch lifting at the edges and make it harder for dirt to collect around the repair.
Used on its own as an inner liner seal, or together with a STEM repair plug — in that combination the plug fills the puncture channel from the outside while the patch seals and reinforces the repair from the inside. The slit mylar backing is peeled off right before the patch is applied to the prepared, cement-coated inner liner surface.

Frequently Asked Questions
How does this patch differ from the radial repair inserts in the AR line?
Radial inserts (such as 2-11-AR710) contain cord layers matched to the radial tire structure and are for radial tires only, providing structural reinforcement at the repair. The universal patch 11-307 has no cord and suits both radial and diagonal tires, including use with STEM plugs. It's the right choice for standard nail puncture repairs where cord reinforcement isn't required.
Can this patch be used without a STEM plug?
Yes — the patch works as a standalone inner liner seal for a nail puncture. A STEM plug is an optional component that fills the puncture channel from the outside; combined with this patch, it forms a complete nail puncture repair meeting the technical requirements for that type of damage.
Which cements work with the 11-307 patch?
The manufacturer recommends Xtra Seal Standard cement (14-008) or Super-Blu (14-511) for cold-cure vulcanization. After mounting, sealing the patch edges and buffed surface with Sealiner is recommended.
