Frequently Asked Questions

How does this compare to separate plug and patch repairs?

The KEX-387 combi-unit combines both repairs in one step, saving installation time while providing superior holding power. The patch seals the inner liner while the plug fills the puncture, creating a permanent repair that's stronger and more reliable than using either method alone.

What size tire punctures can these patches repair?

These tire repair patches work on punctures up to 6mm (1/4 inch) in diameter. The injury angle should not exceed 25 degrees from vertical for proper installation and optimal seal integrity. Use only on nail holes, screws, or similar punctures - not suitable for sidewall damage or large tears exceeding the maximum size limit.

Can I use these on both tubeless and tube-type tires?

Yes, the KEX-387 universal patches work effectively on both tubeless radial tires and traditional tube-type tires. They're specifically designed for passenger cars and light trucks across both tire construction types. The vulcanizing compound bonds permanently to rubber regardless of tube configuration, making them suitable for older and modern tire designs.

Do I need special tools to install these tire repair patches?

While the built-in pilot wire makes installation easier, you'll achieve best results using KX-511F cement and carbide cutters (CC-6, CC-10) to properly prepare the injury site. The pilot wire eliminates the need for separate insertion tools by guiding the stem through smoothly, but proper surface preparation ensures maximum adhesion and longevity.

Just reach out to us after your purchase and we'll connect you with trusted installers in your area. You can negotiate pricing and scheduling directly with them, or we can help coordinate the whole process for you.
