Also known as semi-pneumatic wheels, these have a tough, puncture-resistant tread surrounding a nonpressurized pocket of air to cushion like a pneumatic wheel without going flat.

These wheels consist of an air-filled rubber tire on a steel rim and are among the quietest, most shock-absorbing wheels available.

These lightweight wheels are commonly used on carts. They are filled with compressed air to provide the best shock absorption and a quiet ride.
