In 1940, Walter and Tom Davies invented the world's first spare tire for the car. Today, the spare tire has been used as a standard for the car and appears in the configuration list. In the case of temporary tire puncture, the vehicle plays an important role, and the driving safety is guaranteed to a certain extent. However, it is used less frequently, and there are problems such as increasing the weight of the vehicle and increasing the maintenance cost. With the development and innovation of automotive technology, such as the emergence of new tire technologies such as explosion-proof tires and tire repair fluids, the problem of temporary tire blowout has been effectively solved, and it has gradually become a substitute for spare tires.
No spare tires have become the trend The first domestic "Featured Vehicle Spare Tire Application Trend Report" pointed out that in the passenger cars listed in the past 15 years, the comprehensive placement rate of spare tires is 88.70%, and the configuration ratio of full-size spare tires is 45.78%. The proportion of non-prepared tires accounted for 11%.
With the development of new tire technology such as explosion-proof tires and fast tire-filling fluids, the application of automotive spare tires has evolved from full-size spare tires to non-full-size spare tires and no spare tires. The proportion of application of full-size spare tires is decreasing. In 2004, the proportion was around 83%. By 2016, the application rate was only 26.0%. Since 2013, the allocation rate of spare tires for automobiles has increased. In 2016, the ratio of spare tires without spare tires was 15.47%.
Alternatives to spare tires are favored by new energy vehicles. With the improvement of light weight and energy conservation and environmental protection requirements, new energy vehicles are developing more and more rapidly. Hybrid and pure-powered vehicles are more likely to choose no spare tires or non-full-size spare tires than conventional fuel vehicles. The "Report" shows that the spare tire placement rate of traditional fuel vehicles is still maintained at a high level, and the configuration rate of full-size spare tires has reached 45.08%; the spare tire configuration rate of hybrid vehicles is slightly lower than that of fuel vehicles, but it has also reached 62.33%. Mainly because some of the models are modified by the traditional fuel car power system, maintaining the original full-size spare tire configuration; the proportion of pure-powered vehicles without spare tires reached 49.21%, and the new technology such as fast tire repair received pure The favor of the power car.
Effective weight reduction for lighter weight The current tire repair kits from major automakers typically weigh 5-6 pounds (about 2.2-2.7 kilograms) and temporary spare tires weigh 30 pounds (about 13 kilograms). Or heavier, full-size spare tires plus a toolbox weighing 50 pounds (about 23 kg) or more, which means that the tire repair kit can reduce 40-50 pounds (about 18-23 kg) than the spare tire. ).
The full-size spare tire plus the toolbox has a large overall weight, which is undoubtedly contrary to the current lightweight development of automobiles. Moreover, this weight is unacceptable to the average female driver, so it can be said that for most female drivers, the existence of a full-size spare tire is very tasteless. In contrast, the lighter weight of the tire fluid is more practical.
New fast tire repair tools are popular With the continuous advancement and development of automotive technology, new technologies will replace traditional technologies to contribute to the advancement of the automotive industry. Traditional car spare tires have problems such as heavy weight, low usage rate, inconvenient use, and high maintenance cost. New tire technologies such as new explosion-proof tires and fast tire repair tools are gradually gaining popularity, and there is no trend in car spare tires. It is believed that under the dual interests of lightweighting and energy saving and environmental protection, the carless tirelessness will be the future of the development of the automobile spare tire market.
