Reimagining the wheel, by reinventing the tire

No matter how many rocks it rolls over, this "Superelastic tire" will return to its pre-deformed shape like nothing ever happened. Originally created for future Mars missions, NASA researchers believe that this technology has the potential to someday revolutionize earth tires.

This is where the SMART Tire company comes in.

The SMART Tire Company is an official licensee of the full SMA tire technology suite and engaged in an ongoing public/private research partnership with NASA scientists & engineers to continue the development of the METL bicycle tire (The first commercial product of the SMART tire company).

About the SMART Tire:

The SMART Tire (Shape Memory Alloy Radial Technology) will be a viable alternative to the conventional pneumatic tire (Air-filled). Innovators at NASA's Glenn Research center have been developing this technology for years, a game-changing, non-pneumatic, compliant tire. This innovation, originally called the Superelastic Tire, was designed for future Moon and Mars missions, but could eventually be a replacement for pneumatic tires here on Earth.

This technology represents the latest evolution of the Spring Tire which was invented by NASA Glenn and Goodyear and inspired by the Apollo lunar tires. It is now being further tested and developed for commercialization by The SMART Tire Company.

The novel use of shape memory alloys capable of undergoing high strain as load-bearing components, instead of typical elastic materials, results in a tire that can withstand excessive deformation without permanent damage.

Using shape memory alloy as radial stiffening elements can also increase the load-carrying capacity of the tire. The Superelastic Tire offers traction equal or superior to conventional pneumatic tires and eliminates both the possibility of puncture failures and running "under-inflated", thereby improving automobile fuel efficiency and safety.

Also, this tire design does not require an inner frame which both simplifies and lightens the tire/wheel assembly. SMART tires made from shape memory alloys are fundamentally different from anything available on the market today.

Airless tires are never flat. Flat tires are the #1 problem in the tire industry. By removing air pressure from the equation, SMART tires are safer and require less maintenance. According to the NHTSA, there are over 11,000 tire-related crashes every year. Underinflated tires also reduce fuel efficiency in all vehicles.

Elastic like rubber, yet strong like titanium, this radial design can support 20,000 lbs with a single tire, more than enough for a fully loaded semi-truck, or the landing gear of a 737 jet. This isn't the limit either; novel designs can go even farther when we need them.

Longer lasting & eco-friendly. With a tire that can last the lifetime of the vehicle, we can save billions of pounds of waste, tens of billions of hours of maintenance, and increase the fuel efficiency of vehicles worldwide.
The advantages of this type of tire are obvious. Not only does it eliminate potential issues with temperature or pressure affecting a gas-filled tire, but it also eliminates the possibility of deflation.

SMART tire commercial products will be encased in a special rubber & polyurethane integration (tread, sidewalls, etc.), which could last much longer than the standard carbon black tire. Unlike NASA’s mesh prototype in the photo, STC’s new tires will have no metal in direct contact with the ground or road for the iteration of this technology.

What are the benefits?

Strong - Can withstand excessive deformation
Robust - Can be configured for high traction on various terrains
Simple - Eliminates the need for air
Versatile - Tire stiffness can limit the energy transferred to the vehicle
Lightweight - No inner frame needed for the tire/wheel assembly
Clean - Environmentally friendly, no major tire waste
