A PU foam-filled tire is a "rubber like" tire, that is more durable than EVA yet still lightweight. It's ideal for multiple terrains. The City Select (front wheels only) and City Premier feature this type of tire.
A Forever-Air tire is a rubber tire inflated with a lightweight foam instead of air. This ensures the tire will not go flat with frequent use or rough terrain. This is our most all-terrain tire. The City Mini GT, City Elite, and City Select (rear wheel only) all feature Forever-Air tires.
