What is the normal tire pressure data?

1 Answers

07/29/25 10:35pm
According to the regulations and requirements of the international GBT2978-2008 standard, the tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Hazards of overinflated tires: Reduced friction and adhesion of the tire, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreased puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to abnormal heat generation due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire deformation, making the sidewalls prone to cracks, and generates flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area, accelerating shoulder wear.

What Do Fog Lights Look Like?

Fog lights are divided into front fog lights and rear fog lights. Front fog lights are usually bright yellow, while rear fog lights are red. The symbols for rear fog lights are slightly different from those of front fog lights: the light lines of the front fog light symbol point downward, whereas those of the rear fog light symbol are parallel. These symbols are generally located on the dashboard inside the vehicle. Below is additional information: 1. Introduction to Fog Lights: Fog lights typically refer to automotive fog lights. They are installed at the front and rear of a vehicle to illuminate the road and provide safety warnings during rainy or foggy weather, thereby improving visibility for the driver and other road users. 2. Purpose: The function of fog lights is to make the vehicle visible to others in conditions of reduced visibility, such as fog or heavy rain. Therefore, the light source of fog lights needs to have strong penetration. Most vehicles use halogen fog lights, while xenon fog lights are a more advanced option. Fog lights must be installed below the bumper and as close to the ground as possible to ensure their effectiveness. If installed too high, the light may not penetrate the fog or rain to illuminate the road (as fog is generally thinner below 1 meter in height), which could lead to dangerous situations.

What Causes Excessive Resistance in the Driver's Seat Belt Pretensioner?

Excessive resistance may indicate an open circuit, wiring issues, or problems with the tensioner. You can disconnect the electrical connector of the tensioner, use a wire to short-circuit it, and clear the fault code. Here are the relevant details: Possible causes: If the fault code changes to indicate low resistance, it suggests an issue with the tensioner. If the resistance remains high, disconnect the ECU's electrical connector and use a multimeter to check the continuity of the two wires. If the wiring is intact, the issue may lie with the ECU. Another possibility is poor contact in the tensioner's connector. Pretensioner seat belts: Pretensioner seat belts, also known as pre-retracting seat belts, are designed to tighten the webbing instantly during a collision before the occupant moves forward, securing them firmly to the seat. The belt then locks to prevent the occupant from leaning forward, effectively protecting their safety. The retractor in a pretensioner seat belt differs from that in a standard seat belt. In addition to the standard retractor's function of extending and retracting the webbing, it can also increase the restraining force on the occupant within approximately 0.1 seconds when the vehicle speed changes drastically. Therefore, it includes a control device and a pre-tensioning mechanism.

Do new energy vehicles emit radiation harmful to the human body?

New energy vehicles do emit radiation, but the impact on the human body is almost negligible. Currently, the actual radiation levels of most electric vehicles are below 10uT, which is even lower than the radiation from daily smartphone usage. Below are extended details: 1. International EMF Standards: The World Health Organization (WHO) advocates for the establishment of electromagnetic field limits and other control measures that provide the same or similar levels of health protection globally. It has endorsed guidelines developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and encourages member states to adopt these international guidelines. Based on scientific assessments of health risks, exposure thresholds for electromagnetic fields have been established. The criterion for determining these thresholds is whether health hazards are detected above these levels. The ICNIRP guidelines set occupational exposure limits at 1/10 of the threshold and public exposure limits at 1/50. 2. China's Electromagnetic Environment Standard Development Principles: The ICNIRP recommended standards for electromagnetic radiation exposure limits are based on scientific data concerning thermal effects and immediate effects. Countries worldwide have developed national standards that are equal to or stricter than these recommendations. China's electromagnetic environment standards adopt the 'precautionary principle' recommended internationally to mitigate potential adverse effects from unknown factors. These standards reference ICNIRP guidelines with additional margins, resulting in stricter exposure limits than those set by ICNIRP.

What are the differences between the high and low configurations of the Hongqi H5?

Here are the differences between the low and high configurations of the Hongqi H5: 1. Exterior: The most significant difference between the lowest and highest configurations of the Hongqi H5 is the wheels. The low configuration comes with 17-inch wheels, while the high configuration features 19-inch wheels. 2. Powertrain: The low configuration is equipped with a 1.5T engine paired with a 7-speed wet dual-clutch transmission, delivering a maximum horsepower of 169 HP and a maximum torque of 258 Nm. The high configuration, on the other hand, is powered by a 1.8T engine mated to an Aisin 6AT transmission, producing a maximum horsepower of 197 HP and a maximum torque of 320 Nm. The high configuration offers significantly more power than the low configuration, and the inclusion of the superior Aisin 6AT transmission enhances the overall driving experience. 3. Interior: The lowest configuration does not come with a cruise control system, whereas the high configuration is equipped with an advanced full-speed adaptive cruise control system. In terms of driving modes, the low configuration only offers a sport mode, while the high configuration provides sport, standard, and economy modes. There is also a notable difference in the seats: the low configuration uses faux leather, while the high configuration features genuine leather. Additionally, the high configuration supports front seat ventilation and heating, as well as rear seat heating, offering greater comfort.

What does the V in tire specifications stand for?

Tire specifications with a V indicate the speed rating of the tire. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims to support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires often operate under complex and demanding conditions, requiring high load-bearing, traction, and cushioning capabilities. The functions of tires include: 1. Working with the vehicle suspension to mitigate impacts during driving; 2. Ensuring good ride comfort and smooth driving; 3. Maintaining excellent adhesion between the wheels and the road surface; 4. Enhancing the vehicle's traction, braking, and off-road capabilities; 5. Supporting the weight of the vehicle.
