Tire is a round elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground.
1845, R·w· Thomson, a Scottish-born civil engineer, invented pneumatic tires, and obtained a patent from the British government. The patent name was "Wheel Improvement of Carriage and Other Vehicles".
The first pneumatic tire was born in February 10 of the same year. Tires are usually installed on metal rims, which can support the car body, buffer external shocks, achieve contact with the road surface and ensure the driving performance of the vehicle.
