Goodyear automobile tires: Goodyear tires
Goodyear Tire & Rubber Company was established in 1898, with a history of more than 100 years. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company produces tires, engineering rubber products and chemical products in more than 90 factories in 28 countries. Today, Goodyear has more than 80,000 employees worldwide.
1898 America, all kinds of vehicles on the road. From horse-drawn carriages to newly born cars, there is an urgent need for a cushion that can cushion the impact of the road surface. So Frank Sabrin bought a cardboard factory in the east of Akron, Ohio, and began to produce rubber products. In memory of the invention of 1839. Sulfide Rdquo Charles & amp Mido goodyear, the two brothers named the company &; Goodyear tire rubber company; , and then select &; Ldquo flies. For trademarks, it means elegance and quickness.
Goodyear automobile tires: products
As one of the largest tire manufacturers in the world, Goodyear has been making unremitting efforts to develop new products to meet the ever-changing market demand. Goodyear introduced pneumatic tires on 1899, and obtained the patent of tubeless tires as early as 1903. Then in 1909, pneumatic tires for airplanes and trucks were introduced. Four years later, Goodyear &; Ldquo airship &; Rdquo (Helium-filled airship, which can be used for propaganda and military); 19 17, Goodyear started long-distance truck transportation business &; Ldquo People's Rapid Transit &; Rdquo, which proves the durability of its tires. During World War II, in addition to tires, Goodyear also began to manufacture artificial rubber and made more than 4,000 planes for the Allied Forces. 1947 introduced nylon cord tire, and 1962 polyester cord tire became the industry production standard.
After 1950s, Goodyear began to diversify, focusing on developing new products other than tires. 1970. Apollo; 14 The tires of the empty crane that astronauts landed on the moon were developed by Goodyear Company, which further recognized Goodyear's ability to produce high-quality tires.
Goodyear automobile tires: tire maintenance
1. First of all, you need to choose tires suitable for your running. Choose the tires of cities, and choose the tires of mountainous areas that often drive on mountain roads.
2. Tire pressure detection. When the tires are cold, that is, three hours after parking or less than 2 kilometers after driving. Check the airbags of all tires under cooling conditions at least once a month.
Including spare tire, the air pressure value is subject to the main parameters advocated by automobile manufacturers. If you find something unusual, you must thoroughly find out the reason. Air pressure is an important indicator of tire life. When the air pressure exceeds 20% of the normal air pressure, the tire life is reduced by 10%, which is lower than 30% of the normal air pressure, and the tire life is shortened by 52%.
3. Prevent foreign objects. In the process of driving, especially at high speed, an inconspicuous pebble can basically cause great damage to tires. Pay special attention during driving. A slight careless cut, poor pattern matching and gasoline and diesel pollution will basically reduce the performance of the tire.
4. If the tire is worn to the wear indicator, stop using it. Most wear indicators are located at 65438 0.6 mm of the remaining depth of the tread groove.
5. Wheel alignment and balance and tire alignment. Because of the different tire positions and other factors, the wear of the front and rear wheels of the tire is different, and tire centering can obtain the best tire wear state and prolong the service life. Most tires can travel 8000- 1000 km, but if uneven tread wear is found, they should be replaced as soon as possible.
6. Avoid tire aging damage. Because tires are rubber products, you must be careful not to touch chemicals such as oil, acid and hydrocarbons when driving, parking or storing tires.
Otherwise, it will cause corrosion, deformation and softening. When parking, it is recommended to park the car in a cool place to avoid premature tire aging and damage caused by direct sunlight. Tire wax can usually be selected for maintenance.
7. In addition, one thing that needs attention is the problem of dog urine. It is found that the bearing capacity and compressibility of tires that are often peed by dogs are basically obviously reduced. You can choose professional products, such as car driving and dog spraying.
