Frequently Asked Questions
How does this compare to a simple tire plug?
The PC-2 combines patch and plug functions for superior strength and permanence compared to plugs alone. While standard plugs only seal the puncture hole, this combi-unit also repairs the inner liner for complete tire integrity and meets industry standards for permanent repairs.
What size punctures can this repair?
This unit is specifically designed for punctures up to 1/4 inch or 6mm in diameter located in the tire crown area only. The 1-7/8 inch patch diameter provides ample coverage for effective sealing of these injury sizes while maintaining proper safety margins. Do not use on sidewall punctures or injuries exceeding this size limit.
Can I use these on both car and truck tires?
Yes, the PC-2 works on passenger cars, light trucks, commercial vehicles, and agricultural equipment with both radial and bias-ply tire constructions. It's compatible with tubeless and tube-type systems, making it versatile for most tire repair applications. However, always verify the injury angle is less than 25 degrees before installation for proper safety compliance.
Do I need special cement for installation?
For best results, use PREMA Ultra Fast Dry Vulcanizing Cement such as PFC-8 or PFC-32. This specialized cement ensures optimal adhesion and creates a permanent chemical bond between the patch and tire rubber. The cement provides long-lasting repairs that withstand harsh road conditions, temperature extremes, and normal driving stresses for the tire's remaining life.
What's the shelf life of these repair units?
PREMA tire repair patches have a 24-month shelf life from the date of manufacture when stored properly in cool, dry conditions away from heat and direct sunlight. Proper storage ensures the rubber compounds maintain their flexibility and bonding properties. Store in original packaging at room temperature and avoid exposure to chemicals or extreme temperature fluctuations.
