Is Tire Pressure Monitoring Necessary?

Tire pressure monitoring is necessary. As a pre-warning safety system, the tire pressure monitoring system can alert the vehicle owner when abnormal tire pressure is detected, prompting timely action to prevent accidents. Through this system, owners can continuously monitor tire conditions to prevent blowouts. Excessive tire pressure reduces the shock absorption effect, increasing the burden on the vehicle's suspension system. Insufficient or uneven tire pressure can lead to braking deviation, accelerating wear on the suspension system. There are three types of tire pressure monitoring: direct tire pressure monitoring, indirect tire pressure monitoring, and composite tire pressure monitoring.

What does full-size SUV mean?

Full-size SUV refers to large SUVs, which are the largest category of SUVs in terms of size. Generally, full-size SUVs have a body length exceeding 5 meters, hence SUVs with a body length over five meters are classified as full-size SUVs. Relevant introduction to full-size SUVs: Main characteristics: Large size, high displacement, and spacious interior. The body length usually approaches or exceeds 5000mm; Engine characteristics: High torque, low power; Space-wise. Full-size SUVs offer ample space, with seating capacity ranging from 5 to 8 seats; Representative models: Nissan Patrol, Lexus LX570, Infiniti QX56, Mercedes-Benz GL450, Toyota Sequoia, Cadillac Escalade, etc. Precautions for driving full-size SUVs: These vehicles have relatively larger blind spots, so extra caution is needed to be aware of smaller vehicles around to avoid risks like scratches, and the rearview mirror angles must be properly adjusted. SUVs are heavier than regular cars, and according to physicists, at the same speed, greater mass means greater kinetic energy, which implies that SUVs require a longer braking distance compared to sedans. Therefore, maintaining a reasonable following distance is essential, and it's also necessary to anticipate road conditions ahead and brake in advance.

How Often Should You Service Your Car?

Car service intervals are typically recommended every 5,000 kilometers or every six months, whichever comes first. However, the actual maintenance frequency may vary depending on the owner's driving habits and operating conditions. Vehicles frequently driven in harsh environments may require more frequent servicing. Car maintenance, also known as vehicle servicing, refers to the preventive work involving inspection, cleaning, replenishment, lubrication, adjustment or replacement of certain components. Its purposes are to maintain vehicle cleanliness, ensure proper technical conditions, eliminate potential hazards, prevent malfunctions, and extend the vehicle's service life.

What Causes the Abnormal Noise When Shaking the Rear Wheels After Parking?

After parking, the abnormal noise when shaking the rear wheels is caused by: 1. Aging of shock absorber springs or rubber; 2. Aging or misalignment of the chassis suspension control arm or rear axle rubber. If the noise is confirmed to be coming from the brake disc area, you can release the handbrake and shake the vehicle again. If the noise disappears, it is a normal sound caused by friction between the brake discs. If the noise persists after releasing the handbrake and the location is not near the brake discs, it is necessary to inspect and confirm the condition of the chassis components. Generally, this issue occurs when the vehicle's handbrake is engaged. When shaking the vehicle, some brand models may produce noise due to friction between the brake discs.

How many types of ABS tire pressure monitoring principles are there?

There are two types of ABS tire pressure monitoring principles: direct tire pressure monitoring systems and indirect tire pressure monitoring systems. The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It then transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, displaying the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. The indirect tire pressure monitoring system works by detecting when a tire's pressure decreases, causing the vehicle's weight to make that wheel's rolling radius smaller, which results in its rotation speed becoming faster than other wheels. By comparing the differences in rotation speeds between tires, it achieves the purpose of monitoring tire pressure.
