Do all four tires need to be replaced at 60,000 kilometers?

It depends on individual driving habits and the duration of use. Although rear tires generally experience less wear, tires that have been used for a long time will age and become unsafe. Check the degree of tire wear: There is no officially certified accurate mileage for tire usage. However, based on the shared experiences of many car owners, generally after driving about 50,000 kilometers, the tread grooves of the tires should be nearly worn out. Additionally, the sidewalls may age and crack under prolonged stress fluctuations, leading to reduced grip and an increased risk of blowouts. Therefore, it is recommended to replace the tires. Judging by wear indicators: Many people may not notice the wear indicators on tires, which are currently the most authoritative standard for determining when tires need replacement. When the tire wear reaches the indicator mark, it means the tread depth is less than 1.6mm, significantly reducing the tire's ability to channel water. This makes driving in rainy or snowy conditions very dangerous.

What Causes a Burning Smell from the Car AC After Starting the Engine?

The reasons for a burning smell from the car AC after starting the engine are: 1. The air intake of the AC is blocked, preventing the hot air inside from being blown out and causing the heat to accumulate, which burns the plastic components; 2. Aging wiring, where the circuit gets scorched by heat during electric heating, or plastic components shifting internally, leading to overheating. Maintenance methods for car AC: 1. Regularly check the refrigerant and compressor oil; 2. Clean the surface of the condenser; 3. Clean the surface of the evaporator. The functions of car AC are: 1. To adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to an optimal state, providing a comfortable environment for passengers and reducing travel fatigue; 2. To create favorable working conditions for the driver, serving as a crucial ventilation device for ensuring safe driving.

Can private cars drive on the highway at night?

Private cars can drive on the highway at night. The precautions for driving on the highway are: 1. Both the driver and front passenger should fasten their seat belts, and the driver should not answer phone calls; 2. Avoid sudden steering wheel movements while driving at high speeds; 3. Do not change lanes arbitrarily while driving. When changing lanes or overtaking the vehicle ahead, the turn signal must be activated in advance; 4. Only use adjacent lanes when overtaking, and immediately return to the driving lane after overtaking. Vehicles must not straddle or drive on the lane dividing line; 5. Do not reverse, drive in the opposite direction, or make U-turns or turns by crossing the central divider. Test driving and driving instructional vehicles are not allowed, and overtaking or parking on ramps is prohibited; 6. Maintain a following distance of at least 100 meters. When the speed is below 100 kilometers per hour, the distance from the vehicle ahead in the same lane can be appropriately reduced, but the minimum distance should not be less than 50 meters.

Where to Place a Phone Holder Without Penalty?

Placing a phone holder on the dashboard or center console will not result in penalties and is also safer, as it does not obstruct the driver's view. Below is more information about phone holders: Suction Cup Car Mount: This type of holder uses suction to attach to various surfaces inside the car, such as the windshield or dashboard, allowing for a more direct view of the phone. However, on rough roads, suction cup mounts may detach, and their larger size can obstruct the driver's view, especially when attached to the windshield. Clip-on Car Mount: Clip-on holders attach to the air vents. Compared to suction cup mounts, they are more compact and do not block the driver's view. They are also more affordable. However, their lower placement (on air vents) makes them less convenient to view and can divert attention, posing potential safety risks. Magnetic Car Mount: As the name suggests, magnetic holders use magnets for secure attachment, making them less likely to fall off—provided they are of good quality. Their small size allows them to be placed almost anywhere in the car, making them a popular choice. However, they require 3M adhesive for installation, which can leave difficult-to-remove marks. Additionally, a metal plate must be attached to the back of the phone, which may affect its appearance.

What does Engine MAX mean?

"MAX" means "maximum." When the MAX button is illuminated on a car's air conditioning system, it represents the strongest cooling mode. For example, after turning on the A/C (air conditioning) switch and then pressing MAX, the air conditioning will activate the strongest cooling mode with the blower operating at maximum airflow. Its purpose is to lower the temperature inside the car as quickly as possible. Here are some related details: Label: The term "max" can be seen not only on air conditioning control buttons but also on various fluid reservoirs in the engine compartment. Here, "max" also carries the meaning of "maximum" or "highest," and some may simply use "M" to denote it. Upper Limit: The "max" marking on fluid reservoirs indicates the upper limit of the fluid level. The highest position of the fluid level should not exceed the horizontal line corresponding to "max." Naturally, where there is an upper limit, there is also a lower limit. "Low" (or sometimes "min" in some cars) represents the lower limit, indicating the minimum fluid level position. This means the fluid level should not fall below the horizontal line corresponding to "low." These markings are most noticeable on the overflow tank (i.e., the radiator). The optimal fluid level is between the upper and lower limits.
