How It Works
Protection where flats start.
GRAI LINE Interlink™ Tire Liners sit between the tire casing and the inner tube—absorbing sharp impacts and stopping punctures before they reach what matters.
Fast Easy Installation
Click. Fit. Ride.
Modular segments interlock and conform to the tire’s curve for a secure fit—without bulky liners or complicated tools.
