PREMA PRE-PB-9 Bias Ply Repair Unit, 13-3/4", 6 Ply (Box of 5)

Q: How does this compare to plug-style tire repairs? A: Patches provide permanent structural repair by bonding to the tire's inner surface, creating a reinforced seal that restores tire integrity. Plugs only fill the puncture hole without structural reinforcement. For commercial applications requiring long-term reliability, patches offer superior durability and safety compared to temporary plug solutions.
