Starting next year, General Motors engineers will work with researchers at the National Tire Research Center in an effort to create safer and more efficient tires. The automaker has invested $5 million in the facility in Halifax, Virginia, which uses cutting-edge tire performance machinery to recreate real-world driving events.

The $11.2 million test equipment can spin a tire to the equivalent of 200 mph while monitoring data on handling, ride, torque and braking forces and replicating various road conditions. GM says tire efficiency can theoretically be increased up to seven percent by varying attributes like tread design, construction and manufacturing techniques.

GM hopes its work at the National Tire Research Center will help the company advance the arrival of next-generation tire technology, thereby increasing vehicle efficiency and reducing fuel consumption at the same time. You can take a closer look at the full press release below for more information.

National Tire Research Center to speed testing, development of fuel-efficient tires

DETROIT – General Motors' drive to improve vehicle fuel economy is expected to gain traction in January when GM engineers and scientists begin work with research partners to accelerate the development of tire technology at the new National Tire Research Center in Halifax County, Va.

The world-class facility, to which GM contributed $5 million, uses state-of-the-art tire performance machinery that will enable automakers and tire manufacturers to replicate real-world emergency events and improve vehicle highway safety.

By some estimates, tire design can help improve fuel efficiency by up to 7 percent. A tire's rolling resistance is determined by variations in tread pattern, construction, material quality and processing techniques. Ultimately, the lower the rolling resistance, the less fuel is needed to move the vehicle forward.

Low rolling resistance tires are expected to help customers save money at the gas pump, as will more efficient conventional engines and electric powertrains.

"The work we'll undertake at the National Tire Research Center will have a big impact on how quickly next-generation tire technologies will be developed and the accuracy of their design and engineering," said Ken Morris, GM's executive director of Global Vehicle Performance and Safety, and proving grounds and test labs. Morris attended the center's ribbon-cutting ceremony in October.

The center's $11.2 million tire performance test equipment, known as Flat-Trac LTRe, is unique in its use of electric motor technology and can run a tire up to 200 mph. It provides data on handling, ride, torque, and braking capabilities on various surfaces, including wet road conditions. GM was instrumental in developing the machine's test specifications.

The Flat-Trac LTRe is capable of replicating all driving maneuvers of a passenger car or light truck on the road. GM and other automotive engineers will be able to use the data collected by the equipment to predict vehicle performance and modify tire characteristics to improve performance for low rolling resistance, better road-holding capability and other criteria.

"This facility's test equipment is like going from a basic telescope to the Hubble – it opens up a whole new world of possibilities," said Frank Della Pia, a former GM vehicle dynamics manager who is executive director for the tire research center. "It can test tires in the full range of the performance spectrum. This facility has no peer in the world. It's going to enable a transformational leap in tire technology."

The center's facilities also include the Southern Virginia Vehicle Motion (SoVa Motion) Laboratory, strategically located in the heart of the Virginia Motorsports Alley at the Virginia International Raceway. SoVa Motion offers shock and suspension testing, virtual prototyping of vehicle components, and a range of on-vehicle sensing such as wheel force transducers. SovaMotion will take advantage of the Tire Center's test data to conduct drive and handling simulations that could help reduce time and cost of vehicle program development.

"The work GM will do with SovaMotion and the National Tire Research Center will further improve laboratory test methods and improve our overall vehicle development process," Morris said. "Ultimately, that means better vehicles for our customers."

      Probably only a matter of time before the National Tire Research Center goes bankrupt.

      The more economic the tire is the less safe the tire becomes. Safety>fuel economy every time.

      I thought there was some CAFE mandate by 2025 to hit some ridiculous mileage. I wonder who will have the fuel saving technology patents.

        Car makers have to hit a 54.5 mpg average by 2025, using the old CAFE test; this is about ~ 40 mpg using the EPA test that currently shows up on the sticker. How doable/how much car makers will have to increase prices or downsize cars & engines will probably depend on how cheap batteries get, since the MPG-Equivalent for electric cars is very high; the Nissan Leaf has a CAFE score of 142 MPG for example, so Nissan could sell two 20 mpg trucks/SUVs for every Leaf, & still have a CAFE score of 60.67 mpg. Hopefully battery prices will drop enough that we can get Tesla Model S batteries/drivetrains in a car with Ford Taurus pricing.

      Not a sexy field but eking out a few percent of efficiency with better tires will help.

      Good to know that GM is doing more research to improve its technology. GM is one of the two main sponsors of EcoCAR 2, a three-year collegiate competition challenges 15 universities across North America to reduce the impact a 2013 Chevrolet Malibu would have without its performance and consumer acceptance. Penn State Advanced Vehicle Team also participated in this competition and they are working hard to success. This second year will be the year with most fun. Good luck, team!

      reckon they can come up with a self balanced tire?
