These innovative tire pressure monitoring caps replace your ordinary valve stem caps and instantly show you if your tires are properly inflated using a simple, easy-to-read 3-color warning system:
Green = Perfect pressure (100% of recommended – safe to drive)
Yellow = Slightly low (drops ~10-20% below recommended – inflate soon)
