Airless Tires

The biggest problem with ordinary tires is air pressure—tire wear, longevity, safety, performance, and durability all rely on air pressure. Air has supported tires since the creation of the pneumatic tire in the mid 19th century.

However, airless tires have been used on utility vehicles such as lawn mowers, bicycles, and wheelchairs for quite some time. For the past few decades, major tire manufacturers have been working on making them for vehicles.

AIRLESS TIRES FOR CARS

Note: airless tires are not the same as run flat tires.

There are a number of pros and cons to airless tires.

Pros include:

• Cannot go flat

• Need to be replaced less frequently

• More eco-conscious construction

Cons include:

• Higher rolling resistance (less efficient)

• Inferior suspension (stiffer, bumpier ride)

• Heat buildup

• Less adjustability to road conditions

Passenger and commercial vehicle tires currently use pneumatic tires, which consist of an airtight inner core and a tread reinforced with a steel belt. They rely on proper air pressure to provide resistance and cushioning on road obstacles while supporting the vehicle.

MICHELIN AIRLESS TIRES

Michelin began developing an airless tire in 2005, integrating a tire and wheel design to create the “Tweel.” Michelin claims the Tweel will offer the same shock absorption, handling, and load carrying characteristics as a traditional tire.

However, it vibrates at speeds above 50mph (80km/h), making it unfavorable for personal vehicles and so is only currently available for golf carts, skid steer vehicles, and ATVs.

When will we have airless tires?

In addition to Michelin, other tire makers are working on their own version of airless tires.

Bridgestone is currently developing the Air-Free Concept Tire that can hold 330lbs (150kg) per tire.

Hankook is working on their iFlex airless tire.

Unfortunately, due to various limitations many tire manufacturers have not yet begun to experiment with airless tire designs. Some brands, including Goodyear, have stated that they don’t expect airless tires to be road-ready until 2030.
