In fact, whether it is a family car or an operating vehicle, how often a car tire needs to be filled is not judged based on time, but based on the tire pressure value of the car tire to determine whether the tire needs to be inflated.It is not that the tire must be inflated once a month or two. What the owner needs to do is to check the air pressure value of the tire within a certain period of time to determine whether it needs to be inflated and pressurized.
Moreover, most family cars now have tire pressure alarm systems. If the tire pressure is normal and the alarm system is not on, then basically the tires are not out of air and there is no need to inflate.However, if the tire pressure warning sounds, the owner needs to check whether the tire pressure is too high or the tire pressure is too low. At this time, you can view the accurate tire pressure value from the car's central control screen. If the tire pressure value is shown to be too low, the owner needs to inflate and replenish the pressure in time.
Although car owners know that car tires need to be filled in time, they don't know how much tire inflation is appropriate.Under normal circumstances, the tire pressure of automobile tires is generally controlled in the range of 230 kPa to 250 kPa, but due to different models, the corresponding standard tire pressure values will be different.
Therefore, the owner can refer to the tire pressure values on the B-pillar and C-pillar of the car door, so that the car tires can be more accurately pressurized. After all, the tire pressure values of the four wheels of most cars are slightly different.If the car owner does not find the tire pressure value as mentioned above when he is pumping, he can also directly observe the value on the tire pressure device and control it within the range of 230 to 250 kPa.
When driving in normal times, you may encounter fever in the
wheels
of the car. Many people may think that the car is damaged or caused by some other reason.This is a very simple question, so don't worry too much.
The reason for its heat may be that the tire rubs against the ground for a long time and then generates heat that will be transmitted to it, and then it will cause its temperature to rise. Another reason is that because of long-term braking, the friction of the brake pads will also produce high temperature conduction to it, causing the temperature to rise.
In fact, this situation occurs because of the heating of the wheel hub. This is a very common and normal phenomenon. You only need to pay a little attention to it. You don't need to enter the repair shop. If the owner is really worried, you can also go to the repair shop to take a look.
It should be noted that in normal times, we must pay attention to its maintenance and repair. If it has some faults but is not found, this is a very dangerous thing. After all, it is used by someone on the car.
Because
aluminum alloy wheels
have the following four characteristics, many cars currently use aluminum alloy wheels：
1.Driving comfort has been improved.
Because aluminum alloy wheels have the metal characteristics of absorbing vibration and rebound, they have high dimensional accuracy after being processed by CNC machine tools.It's really round.Partial swing and small beating.The balance is very good, which can make the car very smooth and comfortable.
2.Fuel-saving and normal driving.
Due to the light weight of the aluminum wheels, the rotational inertia of the four wheels is reduced after replacement, the acceleration of the car is increased, the braking energy demand is reduced, and the fuel consumption is reduced.
3. Improve driving safety.
The heat dissipation coefficient of aluminum alloy wheels is three times that of ordinary steel wheels.At the same time, combined with the structural characteristics of aluminum alloy wheels, when driving for a long time, the heat generated by the tires and braking system is discharged into the air to maintain the appropriate temperature.
4.The beauty of the whole vehicle is improved.
The exterior design of the aluminum wheels is very exquisite.The shapes are diverse, and the integration of the wheels can also be realized to show its beauty and enhance the beauty of the vehicle.
