High-speed body vibration is caused by: 1. Uneven brake disc surface; 2. Large deviation in wheel alignment data, especially incorrect front wheel alignment angles and excessive toe-in; 3. Tire pressure being too high or too low - higher speeds with overinflated tires cause more severe body vibration, while underinflated tires result in floating sensation and pulling; 4. Abnormal tire wear; 5. Rim deformation - when tires are mounted on deformed rims, the tires also deform, leading to uneven surfaces and incorrect wheel dynamic balance, causing vibration during driving; 6. Damaged shock absorbers - at high speeds, the impact from the road surface to the tires is transmitted to the body without attenuation, causing vibration throughout the entire vehicle.

Will a Tire Pressure of 2.7 Cause a Blowout?

A tire pressure of 2.7 will not cause a blowout. The standard tire pressure for most household passenger vehicles generally ranges between 2.3-2.8 bar, which can be slightly higher or lower but should not deviate too much. According to the regulations and requirements of the international GBT2978-2008 standard, the tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Tire pressure reset method: First, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating that the tire pressure reset is complete.

What to Do When a Car Blocks the Way Without Leaving a Phone Number?

If a car blocks the way without leaving a phone number, you can notify the owner to move the vehicle through the following methods: 1. Contact the insurance company: Check the service phone number of the insurance company on the windshield and inquire about the owner's phone number. Additionally, platforms like 12580 and 114 also provide mobile services. 2. Report to the police for towing: If it is confirmed that the other party is illegally parked, you can call 110 to request a tow truck. Of course, this method will cause considerable trouble to the other party, so it is recommended to use it only as a last resort. 3. Call 122 to request contact with the owner: A more reliable method is to call 12122. After providing the license plate number, 122 will directly notify the traffic brigade in the owner's district or county, and the traffic police will be responsible for notifying the owner.

What is the difference between tire and wheel sizes?

The differences between tire and wheel sizes are as follows: 1. Sensitivity: Large-size wheels are generally paired with low-profile tires, giving the entire wheel higher lateral stiffness. This means the wheel deforms less under high lateral forces such as during high-speed cornering compared to standard wheels, offering better sensitivity than smaller wheels. 2. Wear: Large-size wheels are more prone to wear, while smaller wheels have a lower probability of wear. 3. Comfort: For the same vehicle model, smaller wheels result in taller tire sidewalls, meaning thicker tires. Therefore, smaller wheels with thicker tires provide better vibration damping and noise reduction, offering greater comfort than large-size wheels.
