Frequently Asked Questions

How do I use these string inserts?

Clean the puncture with a spiral probe, insert the string plug using the valve stem tool, trim flush, and add lubricant. This is a temporary repair — have the tire permanently patched or replaced soon.

Are these permanent or temporary repairs?

Temporary. String inserts seal punctures for roadside emergency use. Ride to a tire shop for a permanent patch or replacement.

Do I need vulcanizing cement?

No — string inserts do not require cement. They work with a spiral probe and optional string insert lubricant only.

What size punctures can these repair?

String inserts are designed for punctures in the tire tread. They will not seal sidewall damage or large tears.
