I don't know if you have found that compared to the normal tires of the car, the size of the car spare tire is getting smaller and smaller, what is the reason for this? Many car owners said that the main reason is that car companies in order to control the cost, a spare tire saves 100 yuan, if you sell 100,000 cars a year, the accumulation of less, the price of the spare tire alone can help car companies save 10 million yuan, is not very scary? However, I think that the car spare tire is getting smaller and smaller, not only because of the cost, the owner's demand for the spare tire allows the car company to design the size of the spare tire to be smaller and smaller!
Spare tires are used less frequently
Spare tire as the name suggests, the spare tire prepared for the car, the vehicle driving process, once which tire burst or damage, the owner can replace the spare tire in time, not to let the car break down in the middle, it only plays a temporary emergency role. But in real life, China's road conditions are very good, car tires are not easy to damage, car owners of the use of spare tire frequency is very low, many car owners because of a long time do not use the spare tire, even do not know the existence of spare tires, even if they know the spare tire, the owner does not know how to replace the spare tire, did not master the correct way to replace the spare tire, which also makes the existence of the spare tire lose its original meaning. In this case, if the manufacturer makes the spare tire size a little smaller, this is also understandable.
Helps keep driving safely
The role of the spare tire gives car companies a suitable reason, they must design the spare tire as a non-full-size tire. Think about it, if the spare tire is designed as a full-size tire, will the owner repair the damaged tire in time after replacing the spare tire? I think most car owners will use the spare tire for a long time. The spare tire is a new tire, the other three tires are old tires, the degree of wear of the tires is different, resulting in the vehicle can not maintain a stable driving state during driving, which will not only damage the balance / stability of the chassis, but also affect the safety of the vehicle. The spare tire is designed as a non-full-size tire, the owner will repair the damaged tire in time, and then replace the spare tire, which is helpful to ensure the safe driving of the vehicle.
Increase power and reduce fuel consumption
Spare tire sizes are designed to be smaller and smaller, helping to increase vehicle power and reduce fuel consumption. In order to improve the power and reduce fuel consumption, many car companies are now trying to reduce the weight of the vehicle, for example, the introduction of turbocharging technology, the reduction of the displacement of the engine, the use of aluminum alloy cylinder block; reduce the thickness of the body, reduce the thickness of the steel plate; the original 1.5-ton vehicle has been reduced to 1.2 tons of weight, the vehicle fuel consumption is reduced, the power is enhanced, but the safety of the vehicle is reduced. The reduction of the size of the spare tire can significantly reduce the weight of the vehicle, and the damage to the vehicle is almost negligible, and it is not wrong to design it as a non-full-size spare tire, and some car companies even delete the spare tire directly in order to reduce the weight.
Increase the use space of the vehicle
Chinese car owners like vehicles with larger space, not only large driving space, but also larger space in the back box. The spare tire is generally stored in the position below the trunk, if the size of the spare tire is too large, it will occupy a larger space of the vehicle, resulting in the actual use of the space of the owner will be reduced, which will undoubtedly reduce the actual use experience of the owner of the vehicle, in this case, the car companies are more willing to design the spare tire as a non-full-size spare tire.
In summary, the reason why the car spare tire is getting smaller and smaller is not only from the perspective of cost, it is helpful for the safety of the vehicle, the power and fuel consumption level of the vehicle, and the actual car experience of the owner.
