The only thing worse than having a flat tire is having a flat tire because the patch you just applied did not hold. When air bubbles are trapped under a patch during application, they can keep it from fully sealing. The Steelman Tire and Tube Patch Auto Repair Stitcher helps prevent this by allowing you to provide penetrating pressure over the patch as it vulcanizes and cures to force out trapped air bubbles that could compromise your patching job. A few firm passes with this tool's 1 1/2-inch diameter wheel let the deep-cut, gear-like teeth force out air while securely adhering the patch. The large screwdriver-style handle is easy to grip, allowing you to apply pressure comfortably.
