What safety risks may be associated with abnormal tire pressure
1. The national road traffic safety authority (nhtsa) of the united states of america, which has published reports of possible flat tires, with a flat pressure below the standard of 25 per cent and a three-fold increase in the rate of flats; and a one-fold increase in the rate of flats above the standard of 25 per cent
2. Reduction of excessive brake performance, reduction of area of area of surface and ground exposure, reduction of friction, and extension of brake distance
3. Low pressure on additional fuel-consuming tyres, increased area of area of ground and cover, increased friction, resistance and fuel consumption
4. Reducing the life of a tyre is too high and excessive wear occurs in the middle of the tyre; it is too low and excessive wear on both sides of the tyre's face, which can lead to premature write-off。
Is it necessary to install a foetal monitoring system
It is therefore necessary to provide vehicles with additional space for tyre pressure monitoring in case of serious consequences arising from failure to detect a tyre leak. However, in the case of a small number of tires that are thick, since they can easily be detected by drivers if they leak, it is clear that the role of foetal pressure monitoring for this type of vehicle is less obvious。
These rumors about tire pressure are not credible
Need to replace tyres once
In fact, the replacement of tyres is not determined by the itinerary but by the degree of wear or tear of the tyres. If the tire is worn to a certain extent, which affects the safety of the vehicle, it must be replaced, with little connection to the mileage。
Tyres, however, have a certain shelf life, and tyres that exceed the shelf life should preferably not be used. After the warranty period has passed, internal materials (e. G. Rubber) have aged, and tyres should be replaced in a timely manner, although the tires have not yet been worn to the point of replacement。
2. Need to regulate different fetal pressure according to season
The question of whether this theory is correct was mentioned by netizens that the pressure of tyres should be lower in summer and higher in winter. The pressure of tyres increases when the temperature is high and decreases when the temperature is low, which is a physical change, i. E. The principle of thermal expansion。
However, in the day-to-day use of vehicles, there is no need for man-made increases or lower air pressure based on seasonal variations. This is because changes in fetal pressure are within the safety pressure limit of the tyre, as long as they remain close to the standard pressure given by the manufacturer, which can be unexpected in the summer。
Summary
In order to avoid anomalous foetal pressure during the routine use of vehicles, it is a method of indigence examination. However, for those who stick nails in the road, it may be that the leaks are carried out in silence, that failure to pay attention leads to a flat tire and that a tyre is wasted in vain, and it is important to have a tire pressure monitoring system. The original vehicle is currently equipped with a small number of vehicle models monitored with tire pressure, but the owner can still choose to load itself. Experts suggested that, if conditions permit or are installed to monitor foetal pressure, it would be preferable to choose a well-known brand when purchasing the foetal pressure monitor, which would guarantee after-sale services. When selecting, care should also be taken to select chips of better quality。
