It began in the early 1950's when Bob Newton, along with his supportive wife Joyce, began a successful racing career on the small asphalt tracks of northern Indiana. Like many of his fellow drivers, Bob was not satisfied with driving on street tires with their limited sizing options and hard tread compounds. It was during these early days that Bob had a vision to produce his own tires specifically designed for racing. So in 1957 Bob and Joyce began their own business in an old abandoned horse barn in South Bend, Indiana selling tires to local racers... and Hoosier Racing Tire was born.
