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. Their spoked hub keeps them lightweight at larger sizes.

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

These neoprene rubber wheels won't degrade when they come into contact with oil, mild acids, and solvents. They are more resilient than other rubber wheels.

Rugged and long lasting, iron wheels can withstand chemicals, high temperatures, and heavy loads.
