LAKEVILLE, Ind. — Hoosier Racing Tire Corp. co-founder Joyce Newton died Jan. 16 at age 85.
She and her late husband, Bob Newton, started Hoosier Racing Tire in South Bend, Ind., in 1957.
An aspiring racer in the 1950s, Mr. Newton was frustrated by the quality of race tires available at the time, so the Newtons started retreading tires for racing, then got into the new race tire business in 1961 in partnership with Mohawk Rubber Co. of Akron, which up to that point had provided Hoosier Tire with tread rubber.
That partnership lasted until 1978, when Mohawk closed its Akron plant.
In 1979 the Newtons built a plant in Plymouth, Ind., considered the first and only manufacturing plant designed to make tires exclusively for motorsports applications. The Newtons opened a second plant in 1992 for radial tires.
