The Dueler tires on NFL lineman, Terrance Knighton's ride are Bridgestone's toughest SUV tires. In fact, they come with an 80,000-mile treadwear warranty. To prove it, we put Bridgestone engineer Jim, Terrance and his big SUV on a giant treadmill for 80,000 miles. After realizing they're going to be there for awhile, Jim tries to make small talk with the big man. He innocently asks him if he's ever been on a treadmill. Terrance takes offense and awkwardness ensues. Bridgestone. Your Journey, Our Passion.
