Mitas Tires North America Inc. has introduced its premium product line sold in North America. The company says the line accommodates the demands from the farming community with locally made products manufactured at its Charles City, Iowa, radial farm tire factory. All Mitas-made premium tires delivered to U.S. farmers now bear the Mitas brand name. These tires are based on Continental brand agricultural tires, which Mitas has made under license since 2004.
