The M137 is a steer tire designed for operations running 15,000 to 20,000 miles per month where steer tires are typically pulled prematurely due to irregular wear. The high miles per 32nd with minimized irregular wear results in maximum removal mileage. This combined with excellent fuel efficiency and a competitive acquisition point results in a lower cost per mile, making the M137 the leading value alternative steer tire for extreme long-haul applications.
