  • Tire assembly with low-friction interior
    Patent number: 8281833
    Abstract: A pneumatic tire assembly is disclosed. The tire assembly includes a tire body having an interior surface covered with a low-friction material and a tire rim having an interior surface. The tire body is attached to the tire rim such that the interior surface of the tire body and the interior surface of the tire rim define an inner space of the pneumatic tire assembly. The inner space is filled with a gas and the covering of the low-friction material reduces friction between the gas and the interior surface of the tire body.
