On August 23, 1904, the U.S. Patent Office issued a patent for Grip-Tread for Pneumatic Tires ("Pneumatic Tire Tread Grip Increase Device") to the inventor Harry Weed. The chain appeared in the world and began to provide assistance for the driving safety of the majority of car owners on wet and slippery roads.
According to related reports, Wade's invention of tire chains was inspired by local car drivers. In the first few years of the 20th century, even in a metropolis like New York, paved roads were not popular, and cars often slipped on muddy roads. To this end, local car drivers often tied ropes or even vines to their wheels. to increase the grip of the tires.
Wade found that this method was not only cumbersome to install, but also that the ropes would break after a short period of time. In response to these shortcomings, he uses stronger and more durable materials to make anti-skid chains, and makes the installation of such anti-skid chains very convenient, and it only takes 15-30 minutes to complete the installation.
In addition to muddy roads, Wade's snow chains also perform well on ice and snow. Wade subsequently applied for a patent with the US Patent Office for his invention.
In the following 100 years, the members of the tire snow chain family have become more and more abundant, and various materials and shapes such as steel chains and rubber chains have appeared to protect the winter driving of car owners.
Today, according to the materials used to make anti-skid chains, the mainstream automobile anti-skid chains on the market are usually divided into four types: iron chains, polyurethane (beef tendon), rubber, and manganese alloy chains.
Anti-skid chains are specially made with anti-skid chains on rough surfaces to increase the friction with the road surface. In snowy and muddy road conditions, they can protect tires and prevent tires from slipping, so as to ensure the normal driving of vehicles.
