What is the normal tire pressure for highway driving?

1 Answers
DeFinn
07/28/25 7:46pm
For highway driving, a tire pressure of 2.3 to 2.5 bar is normal. The hazards of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance and tire lifespan; 2. Decreased puncture resistance, increasing the risk of tire blowouts; 3. Accelerated wear on the central tread pattern, shortening tire lifespan, increasing vehicle vibration, and affecting the longevity of other components; 4. Excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving, further decreasing puncture resistance; 5. Increased susceptibility to punctures from sharp objects like nails or glass, leading to internal cracks or blowouts under impact.

How to Reset the Pressure Loss Warning on Volkswagen Bora?

Introduction to resetting pressure loss on Volkswagen Bora: First, turn on the car's ignition switch, press the CAR button on the infotainment system on the center console screen, click on Settings, open Vehicle Settings, and then tap the Tire button. Confirm the tire pressure range, adjust the tire pressure accordingly, and drive at a speed of 15 km/h for ten minutes to automatically reset the system. Below is an introduction to common issues related to tire pressure monitoring: 1. The tire pressure monitoring system warning light remains on: If the warning light stays on after adjusting the tire pressure and performing the reset operation, it may indicate a malfunction in the tire pressure monitoring system. A common issue is the sensor's battery running out. 2. Warning light turns on during heavy load: Due to excessive vehicle load, the tire pressure may exceed the preset upper limit. For models with an active tire pressure monitoring system, you can choose to disable the system or adjust the load. The specific operation involves finding the tire pressure monitoring system in the infotainment system and selecting Standard, Comfort, or Full Load under [Load Status].

How to Check the Manufacturing Year of Tires?

To check the manufacturing year of tires, follow these steps: 1. Similar to the production date of a car, the manufacturing date of a tire is marked on the outer side of the tire. You don't need to turn the tire inside out. On the sidewall of the tire, there is a set of numbers. The last four digits of this marking provide information about the manufacturing date. It consists of four digits "aabb". The first two digits "aa" indicate the week of the year, and the last two digits "bb" indicate the year. 2. Generally, the 11-digit number and letters immediately following the "DOT" letters on the tire sidewall represent the identification number or serial number of the tire. The last four digits of the serial number indicate the manufacturing date of the tire. The format for the tire manufacturing date code is: the first two digits represent the production week, and the last two digits represent the production year. For example, if the last four digits of DOT are 0807, it means the tire was produced in the 8th week of 2007, which is around the end of February 2007.

Can Smoking in the Car Be Exhausted by Using the External Air Circulation?

Smoking in the car with external air circulation on. Turning on the external air circulation mode allows outside air to flow into the car while also carrying the smoke out. It is recommended to open the windows when smoking in the car, as this helps the smoke to quickly dissipate with the airflow. If the car makes a vibrating noise when the air conditioner is turned on, there might be several reasons: 1. Dirty air filter: A dirty air filter can cause excessive noise and abnormal sounds. 2. Debris in the blower fan blades: Debris inside the blower fan blades can lead to abnormal sounds. You can check this by turning on the blower without starting the engine to see if the noise occurs. If it does, the issue is likely with the blower. 3. Fan problem: Deformed fan blades or a damaged fan motor in the car's air conditioning system. 4. Worn clutch bearing: A worn clutch bearing inside the air conditioning pump can cause the engine noise to increase when the air conditioner is on. This component cannot be replaced separately and requires the replacement of the entire air conditioning pump assembly.

Can a Car Be Damaged by Sun Exposure?

Prolonged exposure to sunlight can accelerate the aging of plastic components in a vehicle. For example, the dashboard filled with wiring, car doors, and sealing rings around the sunroof edges are particularly vulnerable. Sealing rings, in particular, are prone to aging and cracking after sun exposure, significantly reducing their sealing performance, which may lead to water leakage or seepage. Here are some items you should avoid leaving in your car during summer: 1. Lighters: Small and easy to forget, yet highly dangerous, as they contain liquid butane that can explode when internal pressure increases due to heat. 2. Bottled water: Stored in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not only fail to quench thirst but also pose health risks. 3. Eyeglasses: Especially reading glasses, as their convex lenses can focus sunlight, potentially causing a fire. 4. Perfume (in glass bottles): The volatile components can produce flammable gases, with a critical packaging point of 49°C. Tests show that on a summer afternoon, an uncovered car can reach 65°C in just 15 minutes of sunlight, increasing the risk of explosion.
