Will the Direction Be Out of Control if the Rear Tire Blows Out?

Rear tire blowout will cause the direction to be out of control. The danger of a rear tire blowout is far greater than that of a front tire blowout, especially for rear-wheel-drive models. At the moment of a blowout, the car will immediately fishtail and lose control, with almost no chance of recovery. When a rear tire blows out, the adhesion of one side of the tire disappears instantly, causing the car to immediately sideslip and fishtail, just like a car skidding on an icy road. Under normal circumstances, if a front tire blows out, a left front tire blowout will cause the car to veer to the left, and a right front tire blowout will cause the car to veer to the right. However, with a rear tire blowout, the car will lose steering force and may suddenly experience oversteering, commonly referred to as "fishtailing." In severe cases of fishtailing, the car may spin around, similar to what is seen in movies or live racing broadcasts. Therefore, comparatively speaking, the danger caused by a rear tire blowout at high speeds is more severe. For example, if the right rear tire blows out, the resistance of the blown-out wheel increases by about 30 times, causing the car to experience a clockwise yaw moment. This yaw moment makes the car veer to the right and simultaneously generates a lateral force pointing toward the inside of the blown-out tire, causing the rear of the car to experience a lateral sliding force toward the inside of the blown-out tire.

What are the consequences of not changing the rear axle oil?

If the rear axle oil is not changed for a long time, it is likely to deteriorate, thereby accelerating gear wear. In severe cases, it may also affect the vehicle's fuel economy. Below is relevant information about rear axle oil replacement: Replacement interval: For new vehicles, the rear axle oil should be changed during the 12,000 km maintenance. After that, the rear axle oil should be checked every 24,000 km. If obvious discoloration or thinning is observed, it should be replaced immediately. Screw holes: Generally, the rear axle has two screw holes—one is a vent hole, the bottom one is the drain hole, and the middle one on the axle housing is the oil level inspection hole and filling hole. To check for oil shortage, unscrew the middle screw; the oil level should be level with this screw hole when normal.

Is the Rearview Mirror Heating Function Useful?

The heating function of the rearview mirror is highly beneficial, especially in winter when the mirror is prone to fogging up. Using the heating feature can help dissipate the fog. Below is some relevant information about the rearview mirror heating function: The primary purpose of rearview mirror heating: When driving in rainy, snowy, or foggy weather, the rearview mirror can be heated via the electric heating wires embedded behind the mirror to ensure the mirror surface remains clear. The fixed temperature of rearview mirror heating: After pressing the rearview mirror heating switch, the indicator light on the button will illuminate, and the heating element will rapidly reach a fixed temperature within about five minutes, typically between 35-60 degrees Celsius.

Can Rearview Mirror Heating Be Installed Afterwards?

Rearview mirror heating can be installed afterwards, but the wiring must comply with safety standards and should not interfere with other safety-related circuits. Introduction to Rearview Mirror Heating: The rearview mirror heating function refers to the ability of the exterior rearview mirrors to be heated by electric heating wires embedded behind the mirror surface, ensuring clear visibility during rainy, snowy, or foggy weather. Principle of Rearview Mirror Heating: Electric heating elements (heating films) are installed inside the mirror surfaces of both side rearview mirrors. In rainy or snowy conditions, when the driver activates the rearview mirror heating function, the heating elements quickly warm up to a set temperature, typically between 35-60 degrees Celsius, within a few minutes. This helps to defog and defrost the mirror surfaces.

What causes the rear wheels to sway left and right when going over bumps?

Rear wheel swaying may be related to tires, wheel balance, shock absorbers, etc., such as inconsistent tire pressure or wheel balance issues. Below is an introduction to tire-related concepts: The role of tires: Tires are the only contact point between the vehicle and the ground. The contact area of a car tire is about the size of a human palm. Within such a small area, the tire must withstand enormous forces from all directions to ensure good ride comfort and smooth driving. Tires are also crucial for the safety of drivers and passengers, playing a very important role in vehicle operation. Tire selection: For durability and versatility, you can choose Pirelli STR, a semi-urban, semi-off-road SUV tire suitable for various road conditions. If you prioritize handling performance, Bridgestone HP SPORT, a sporty urban SUV tire, is a good choice. For comfort, consider Continental CC CUHP, a comfort-oriented SUV tire.

Why can't the rear windows roll down completely?

Due to the limited space in sedans, the doors and tires are already crowded together, resulting in a "top-heavy" door design. There isn't enough space in the lower part of the door to accommodate the entire upper glass panel, so only a portion can be fitted. Below is relevant information about automotive glass: Introduction: Normally, the glass used by OEM suppliers follows a zero-inventory approach, meaning the glass manufacturer provides full vehicle glass sets before the car rolls off the assembly line. Thus, the production dates of all glass panels are generally the same. If they differ, it indicates that the glass was removed and reinstalled during assembly, classifying the vehicle as a reworked unit. However, such rework doesn't necessarily imply quality issues—it might just be minor production adjustments. Vehicle condition assessment: Check if the production dates on all glass panels match. If they do, it suggests the car hasn't been in a major collision. If one panel's date differs from the others, it means that piece was replaced. Additionally, if the windshield's production date is very close to your inspection date, avoid purchasing the vehicle.
