Universal EURO Tire Patch 48 mm – Radial and Diagonal, Xtra Seal
Tire repair patch | EURO type, universal | Brand: Xtra Seal | Sold as: 1 pc.
The Universal EURO patch 48 mm from Xtra Seal is the larger variant of the round universal tire patch — 10 mm wider than the 38 mm size, giving a correspondingly wider reinforcement margin around the puncture. It suits punctures left by larger nails, bolts, or self-tapping screws where the 38 mm format wouldn't provide enough coverage. Like the rest of this line, it can be used on its own or alongside a STEM repair plug. The slit mylar backing is peeled off right before mounting. It works with cold and hot vulcanization.
Product Overview – Universal EURO Patch 48 mm 11-309
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 the 11-309 differ from the smaller 38 mm variant (11-307)?
Both are universal EURO patches for radial and diagonal tires, compatible with STEM plugs. The difference is 10 mm in diameter: the 48 mm format suits punctures from larger fasteners where the smaller patch wouldn't leave enough reinforcement margin around the puncture channel.
Does the 48 mm patch work on truck tires?
Yes — the universal EURO patches from Xtra Seal are made for passenger, truck, agricultural, and construction tires. The 48 mm format is especially useful on truck and agricultural tires, where thicker material and higher working pressures support the choice of a wider patch margin.
Which cements work with the 11-309 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.
