Brownfield Engineering & Maintenance is proud to introduce Air Suspension wheels to the Australian market. We are ready to talk to you about transitioning to Air Suspension wheels on your site and joint R&D opportunities.

The Air Suspension Wheel® is a revolutionary new design replacing the OTR tire. OTR tires need to be replaced after a limited amount of time, while the Air Suspension Wheels® are engineered to last as long as the vehicle itself.

Air Suspension Wheel combines an inner steel hub with an outer steel drum which are connected by twelve nitrogen filled air cylinders and six oil filled dampers that provide suspension. On the outer drum, individually bolt-on steel or polyurethane treads are fitted. The bolt-on treaded shoes are individually replaceable.






How It Works

With minimal maintenance, the Air Suspension Wheel® lasts as long as the vehicle does. For specific applications such as loaders that go near furnaces, steel treads can be supplied, making the wheel high heat resistant. The bolt-on treaded shoes are individually mounted and are easily replaced during a fuel stop. The cylinders need a yearly check with the seals designed to last three years. The air cylinders are designed to last ten years, and the wheel’s mud seal is designed to last four years.
The larger Air Suspension Wheel® with rim sizes R51, R57, and R63, can be cut in three segments so therefore up to three wheels can fit in a standard ISO shipping container, reducing the cost of transportation.


The Air Suspension Wheel® cannot explode or overheat, making it safe for workers. It eliminates downtime due to tire failure and is 100% recyclable.

  • No more blowouts
  • No more fire
  • No overheating
  • No more tyre related accidents
  • No more tilting
  • Less skidding with improved traction

High Strain Ductile Steel

The inner wheel and outer tires structures are made from high performance ductile steel which have been welded and bolted together to withstand extreme conditions. The Air Suspension Wheel® has been engineered with a 100 to 200% safety factor.

High Performance Nitrogen Cylinders

The nitrogen cylinders interconnecting the rim and drum have bidirectional movement and have a rated pressure of 2,500 PSI and a burst pressure of 10,000 PSI. The cylinders are hermetically sealed against mud, dust, rocks, and water. Additionally the cylinders have internal lubrication and are sealed with high performance elastomeric seals.

Solid Polyurethane or Steel Treaded Shoes

The solid treaded shoes are designed to last three to five times longer than OTR tyires. These do not overheat and there is little deformation, more over, there is no sensitivity to uneven tread wear. The Air Suspension Wheels® can be outfitted with PU treaded shoes with a hardness range from Duro A55 to D85. Fire retardant treaded shoes are also available.

Life Time

The Air Suspension Wheel® structure is engineered to last as long as the vehicle itself.

Down Time Reduction

Self-aligning, self-balancing, no need for rotation.

Fuel Saving

Potential 3 to 6% fuel saving because:

  • The hub leads the wheel
  • The cylinders store breaking energy
  • Smaller ground contact area reducing rolling resistance

Can be shipped segmented in an ISO container, reducing transportation cost. No environmental regulatory cost involved.
