Title: Dunlop tire is born of love

1888 John Boyd Deng Lupu, a veterinarian living in Belfast, gave his son Johnny a tricycle as a birthday present, but his son didn't seem to appreciate it. After riding several times, he threw the tricycle aside and rubbed his ass and said it hurt me. Considering the good elasticity of the inflatable cow's stomach, Deng Lupu began to modify his son's tricycle.

Scottish veterinarian john boyd dunlop (1840-192 1) specially "developed" it for him. At that time, almost all bicycle tires were just molded with a layer of rubber on the hard rim. Mr. Dunlop's family doctor advised him to drain the water from the tire and inject air-this advice really worked! Inspired by this, Dunlop began to develop a new type of tire. At first, Deng Lupu put the inner tube made of rubber tube on the wooden rim and covered it with linen to increase the wear resistance. 1888 On February 28th, Deng Lupu put this kind of tire on an adult tricycle. The experiment was very successful. He signed a contract with Edelin to produce pneumatic tires for racing cars. Encouraged, Dunlop began to develop real all-rubber pneumatic tires. After research, he found that the reason why pneumatic tires were prone to puncture at that time was that the tire wall was too thin. Deng Lupu used glue to firmly adhere the layers of rubber skins which had been precisely calculated and cut to the tire wall, thus solving the problem of tire puncture. Deng Lupu applied for a patent for this, and then simply gave up his veterinary career and established Deng Lupu Pneumatic Tire Co., Ltd. on 1889. A year later, the first bicycle pneumatic tire production line in Deng Lupu was established in Dublin, the Irish capital. Next, Deng Lupu has developed a bicycle pneumatic tire that is easy to disassemble on the rim, which makes the pneumatic tire have real practical value. By April of 189 1 year, Deng Lupu Company had been able to produce 3,000 bicycle pneumatic tires per week. 1893, Deng Lupu company set up a branch in Hanao, a small town east of Frankfurt, and the "Deng Lupu" brand entered the European continent.
