When driving, there is a saying: "The tire pressure hits 3."0 fuel saving", this seems to be a general consensus, and many car owners are also pitted by such a "fuel-efficient" method. But in fact, hit 3A tire pressure of 0 is definitely a misunderstanding! To figure out what the correct standard tire pressure is, we need to know these things first.
Tire pressure, strictly speaking, is the pressure of the air inside the tire. The level of tire pressure has a crucial impact on the performance and power of the car, such as the Corolla 20 displacement tire pressure is 22 to 25 air pressure, if it is too low, it will lose strength, and if it is too big, it will float. Different models have different load capacity and power performance, and in order for it to really work, the choice of the right tire pressure is very important. Today we will talk about this topic in detail.
1. Why does the tire pressure hit 30 fuel saving is a misunderstanding?
Some people think that the tire pressure hits 30 can improve the rolling resistance of the vehicle, so as to achieve the purpose of fuel saving. In fact, not only does this not save fuel, but it has the potential to have some negative consequences.
High tire pressure increases the contact area between the tire and the road surface, resulting in increased frictional resistance, which increases the power and fuel consumption of the car. Secondly, high tire pressure can also cause the sidewall of the tire to be easily pinched, which will accelerate the aging process of the rubber and shorten the life of the tire. In addition, high air pressure can also stiffen the tires and reduce ride comfort.
In fact, there is a difference in the optimal tire pressure for different cars and tire models. If we keep following the "hit to 3."0 fuel saving" to adjust tire pressure, which will have a negative impact on the fuel economy of the vehicle over time.
2. How much is the tire pressure to save fuel? These two values are the standard tire pressure!
According to relevant studies and the recommendations of authoritative institutions, the ideal tire pressure of the vehicle should be 23 to 25bar. Tire pressures in this range provide optimal grip and comfort while maintaining the vehicle's fuel economy. Therefore, we should adjust the tire pressure according to the recommendations of the vehicle manual or the manual.
Of course, there are a few things to look out for in addition to the ideal tire pressure:
1.Seasonal factors: Tire pressure needs to be adjusted in different seasons. In winter, the temperature is low, and the tire pressure should be appropriately increased to achieve the effect of low pressure and fuel saving; In order to reduce the rolling resistance of the tires in the summer, the tire pressure should be increased appropriately. But be careful not to be too high, otherwise it may affect driving safety.
2.Road factors: Tire pressure needs to be adjusted appropriately when driving on the road. When driving on the road, the tires have more friction with the ground and require higher tire pressure to provide better grip. At the same time, too high tire pressure can also cause the tires to be more squeezed and worn. When driving in off-highway conditions (such as off-road, sand, etc.), the tire pressure can be appropriately reduced to increase friction, thereby improving the passing performance.
So why do some repair shops or shops still tell you to hit 3What about 0? Hey, there might be some tricks in this! They may deliberately inflate the tire pressure to 3 in order to sell your inflatable device0 benefits! It's actually a sales tool! So you must keep your eyes open when choosing an inflatable device!
3. These 2 values are the precautions in addition to the standard tire pressure.
In addition to the ideal tire pressure mentioned above and the tire pressure adjustment methods under different seasons and roads, there are some things to pay attention to::
1.Regular inspection: In order to ensure the normal use of tires and driving safety, car owners should regularly check the air tightness and wear of tires. It is advisable to have a quarterly tire inspection to replace overworn-worn tires and adjust tire pressure.
2.On-board inflator pump: In the field or emergency situation, we need on-board inflator pump to inflate quickly. When choosing an inflatable pump, you must choose a brand with reliable quality and stable performance to ensure the efficiency and quality of the inflatable pump.
Now do you understand? "The tire pressure is 30 fuel saving" is a big pit! The correct approach should be to adjust the tire pressure according to the vehicle model and seasonal factors.
