Recently, the “2017 Commercial Vehicles Annual Forum†was held in Beijing. This forum attracted many people from the national ministries, experts, scholars, and automobile companies. It is understood that at this annual forum, Goodyear RHTII super single tire won the "2017 commercial vehicle industry tire of the year". It is understood that at present, the use of super single tires in Western countries has become very common. Goodyear RHTII Super Single is a wide base radial tire. In China, in the past two years, with the increasing demand for energy saving, emission reduction and light weight, super single tires are gradually becoming the standard of some commercial vehicles. On July 26, 2016, the “Outline Size, Axle Load and Quality Limits for Automobiles, Trailers and Automobiles†(ie, the new GB1589) was released, further affirming the status of super single tires.
