Tires are one of the important parts of the car. They are in direct contact with the road and work with the car's suspension to mitigate the impact of the car while driving, ensuring the car has good ride comfort and smoothness; ensuring good adhesion between the wheels and the road, improving the car's traction, braking and passability; bearing the weight of the car, the important role that tires play in cars has attracted more and more attention.
With the emergence of automobiles in 1895, pneumatic tires were widely developed. The first automobile tire samples appeared in France in 1895. They were single-tube tires made of plain canvas, with tread rubber but no patterns.
Burley Mill in England invented the cord in 1892 and used it for production in 1910. This achievement not only improved the quality of tires and expanded the variety of tires, but also made it possible to mold the outer tires. With the improvement of tire quality requirements, the quality of cords has also been improved. Cotton cords were replaced by rayon. In the late 1950s, rayon was replaced by nylon and polyester cords with better strength and heat resistance. Steel cords have strong competitiveness with the development of radial tires.
Matt created carbon black reinforced rubber in 1904. The large-scale use of carbon black in reinforcing tread rubber was only after the use of tire cords. Before that, canvas was damaged faster than the tread during tire use. The amount of carbon black in the rubber compound increased rapidly. In the 1930s, the amount of carbon black used in every 100 parts of raw rubber was only about 20 parts. At this time, carbon black was mainly used on the tread and not on the carcass, which had reached more than 50 parts. Before adding carbon black to the tread, the tires were polished after only driving about 6,000km. After adding carbon black, the mileage of the tires was significantly improved soon. A set of truck tires can travel approximately 100,000 kilometers, and even up to 200,000 kilometers on good roads.
From 1913 to 1926, he invented cord and carbon black tire technology, laying the foundation for the development of the tire industry. With the standardization of tire outer edges, the gradual improvement of manufacturing processes, the production speed has increased than before, and the output of tires is increasing day by day.
With the development of the automobile industry, tire technology has been continuously improved and improved. For example, from the early 1920s to the mid-1930s, passenger car tires transitioned from low-pressure tires to ultra-low-pressure tires; in the 1940s, tires began to gradually transition to wide rims; in the late 1940s, tubeless tires appeared; in the late 1950s, low-profile tires came out, etc. The emergence of many new technologies is none other than the radial structure tire pioneered by the French Michelin Company in 1946. This type of tire is known as a revolution in the tire industry due to its significant improvement in service life and performance, especially its ability to save fuel during driving. Here is a brief introduction to the main characteristics of tires developed today.
