In June 2019, the company developed 355/50-20 pneumatic profile solid tires for the specific use of self-propelled modular transporter (SPMT), and successfully solved a series of problems caused by tire in-place steering under high load of module transport vehicles: the torsional rigid support of the tire body, the torsional displacement between the tire and the steel rim and the torsional stress shear of the tire tread patter. Those products were successfully used among SPMT famous manufacturers.
