In April 2013, Kumho launched Wattrun, an electric-car tire brand. At the time, the company pledged to ramp up efforts to take an early edge in the emerging electric vehicle market. According to Kumho’s in-house test results, its electric car tires were 11% lighter than average tires of the same size in the market, and they recorded 18% less rolling resistance. In October 2013, Kumho signed an exclusive deal to supply tires for the Korean car manufacturer Renault Samsung Motors’ all-electric compact SM3 Z.E. until 2018. The company also produces original-equipment tires for Kia’s Soul EV.
