Traditionally conducted during the first week of May, the Tire Rack One Lap of America organized by Brock Yates remains the legitimate evolution of his infamous Cannonball Baker Sea-to-Shining Sea Memorial Trophy Dashes of the 1970s. As such, the annual Tire Rack One Lap of America continues to pique the interest of automotive manufacturers and driving enthusiasts from across the country and around the world.

Brock Yates' original Cannonball New York to Los Angeles route and later Time/Speed/Distance Rallies were replaced in 1992 with the current One Lap of America format. The weeklong event places its emphasis on vehicle preparation, highway endurance and racetrack performance with long transits interspersed with competition taking place as time trials on tracks across the country. No support crews are allowed and the set of tires raced on the tracks must be the same street-legal high performance tires used on the streets. While overall and class scores are based on competition at the tracks, the driving teams must also overcome the challenges of weather, traffic and mechanical gremlins as they transit some of the world's fastest street-legal cars between many of America's premier racetracks, such as Daytona International Speedway, Road America and Sebring International Raceway.

The Tire Rack Team hosts One Lap of America competitors to a wet skidpad challenge on our test track as each year's first competition event and a dry skidpad challenge (weather permitting) as its last. Finishing positions in the skidpad challenges are awarded by timing laps in both directions on the test track's 200-foot diameter skid pad and calculating the average cornering forces each vehicle generates.

Spectators are welcome to visit Tire Rack in South Bend to see the cars during their final preparation and to watch both skidpad events. There is no admission fee and parking is free.

While there may be other endurance driving events that vaguely resemble this one, there is only one Tire Rack One Lap of America.
