Product description – EURO radial repair unit 4-ply 2-11-744
Unit 2-11-744 is used for crown area repairs in radial tyres where maximum reinforcement with four cord plies is required. The elongated shape of 121×330 mm allows coverage of an extensive damage zone along the tyre circumference, making this unit particularly useful for sectional repairs and longitudinal crown damage. The radially aligned cord plies distribute stress evenly across a wider area, improving repair durability and reducing the risk of re-damage even under intensive operating conditions.
The black rubber is bonded to blue active rubber, which ensures a strong and durable bond with the prepared tyre surface. The scored mylar backing allows quick and clean removal of the protective layer immediately before installation, without risk of contaminating the bonding surface.

Frequently asked questions
How does unit 2-11-744 differ from units 2-11-742 and 2-11-740?
All three units have the 4-ply designation and an identical number of cord plies. They differ in size – 121×330 mm (2-11-744) is the longest unit in the group, designed to cover an extensive damage zone along the tyre circumference. Unit 123×250 mm (2-11-742) is wider, while 98×187 mm (2-11-740) is the smallest. The choice depends on the shape and size of the damage and the required repair coverage area.
How does a 4-ply unit differ from 3-ply, 2-ply and 1-ply units?
The number in the designation (1-ply, 2-ply, 3-ply, 4-ply) indicates the number of radial cord layers. The 4-ply unit has the maximum number of plies in the EURO Xtra Seal range and is designed for the most demanding repairs – large damage requiring maximum reinforcement, where units with fewer plies are insufficient. Selecting the correct unit depends on damage size, tyre type and the repair zone.
Which cements should be used with unit 2-11-744?
For cold vulcanisation, Xtra Seal vulcanizing cements are recommended: clear 14-008 or blue Super Blu 14-511. For hot vulcanisation, Black Vulc Cement (4-14-515) is used. After installing the unit, sealing the edges and buffed surface with Sealiner (4-14-128A) is recommended.
