Frequently Asked

Yes. In a case where a screw has caused a puncture, the sealant will form a protective coating around the threads. The tire will continue to perform as normal with the screw inside, permanently sealed. We recommend that it not be removed from the tire. The head of the screw will wear off as the vehicle is driven and it will not do any damage to your tire. Most drivers will never even realize they ran over a screw because their tire will not lose air pressure.

If driving with a screw inside your tire makes you uncomfortable, or if multiple screws are embedded in the tire causing an imbalance, you may simply have them removed by a tire professional. In most cases, the hole created when removing the screw will seal itself. However, if removal of the screw results in a large hole or a jagged tear in the tire, it may require a patch. Always consult the tire manufacturer safety guidelines before patching or repairing any tire. Any manual removal of the screw that results in damage or an unsealable hole in the tire is not covered under our product guarantee.
