Frequently Asked Questions
How does tire sealant work?
You pour it into the tube through the valve stem. The liquid coats the inside and seals punctures instantly as they happen — thorns, glass, and small debris get sealed before you lose air.
Can I use this with tire liners?
Yes. Sealant inside the tube plus puncture-proof liners or Tannus Armour inserts outside the tube gives you maximum flat protection.
