Frequently Asked Questions

What size punctures can this tire repair patch fix?

The PREMA PC-3J combi-unit is specifically designed to repair crown injuries up to 5/16 inch (8mm) in diameter on both radial and bias-ply passenger and light truck tires. The 2-inch round patch provides adequate coverage for punctures within this size range, ensuring a strong permanent seal when properly installed with vulcanizing cement.

How does this compare to separate plug and patch repairs?

This combi-unit replaces separate plug and patch steps by integrating both functions into one component. The single-piece design reduces installation time, helps prevent air leaks between parts, and improves consistency across repairs compared to two-piece systems that require separate stem insertion and patch application.

What angle limitations apply to this tire repair patch?

The PREMA PC-3J combi-unit must only be used for crown injuries with an angle of less than 25 degrees from perpendicular. Injuries at steeper angles create stress concentrations that exceed the repair capabilities of combi-units, requiring two-piece stem and patch systems designed for angled punctures to ensure safe, long-lasting repairs.

Do I need special tools to install these tire repair patches?

Professional installation requires a PCC-3 carbide cutter to prepare the injury, PREMA PF-8 vulcanizing cement for chemical bonding, and PLOS-16 innerliner sealant for system integrity. The included lead wire guide facilitates precise placement during the repair process for professional-grade results.
