Texas Proving Grounds

Near Fort Stockton, Texas, midway between El Paso and San Antonio, lies one of Bridgestone Americas’ most valuable educational assets: Bridgestone Americas’ Texas Proving Ground (TPG). Established in 1955, TPG is more than 6,000 acres of flat land that features a variety of test tracks and driving environments. At TPG, tires and vehicles can be tested to their limits in real-life conditions.

The facility is home to simulated highways, city streets, a giant “black lake” of asphalt and an oval track larger than those at Daytona and Indy. There are tracks that can be run in wet or dry conditions over rumble-strips, potholes, curbs and any other surface that drivers in normal — or abnormal — driving conditions may face.

TPG also gives invited visitors the opportunity to learn about tire technology, observe the complexity of tire testing and possibly gain some hands-on driving experience.

 

TPG Objectives
TPG helps Bridgestone Americas promote safe travel by:

  • Providing exceptional technical testing capability for ride, handling, noise, traction and other OEM and fleet requirements
  • Consolidating most on-road tire evaluation into an efficient location with flexibility for expansion
  • Maintaining a world-class facility that is a state-of-the-art place to work
