More specifically, Nokia tires and Nokia mobile phones belong to Nokia. Later, Nokia phones became stronger and stronger, and they were separated. Finnish Nokia Tire and Nokia Mobile set up their own companies. Later, Nuoji Tire produced the first winter tire in the world at 1934, which can be said to be the originator of winter tires. And in the field of winter tires, we have also obtained a number of patented technologies. Haha, that's all I know. You can go to official website for details.
