How Long Can Tires Be Stored Before They Are Considered Stock Tires?

Normally, tires that have been stored for more than one year can be considered stock tires. In fact, there is a set of numbers on the sidewall of the tire, where the last four digits represent the manufacturing date—the first two digits indicate the week of the year, and the last two digits represent the year. By calculating this, you can determine whether the tire is a stock tire. More details about tires are as follows: 1. Tires are rubber products, and their storage is affected by humidity and temperature. Rubber is sensitive to environmental temperature and humidity, and over time, aging occurs. 2. Various chemical substances inside the tire require some time to be released and stabilized. Only after stabilization can the tire's wear resistance reach an ideal state, allowing for longer use and mileage. 3. Tires that have been stored for three years after manufacturing are considered expired. The rubber in such tires has aged, significantly reducing comfort and increasing the likelihood of cracking. Heat dissipation also deteriorates, greatly impacting acceleration and braking performance. High-speed driving with such tires is highly prone to blowouts, seriously endangering the safety of the driver's life and property. Purchasing expired tires is strictly prohibited. If you find any merchants selling expired tires, you can directly report them to the Consumer Protection Association.

Can New Energy Vehicle Quota Be Changed Back to Regular Quota?

New energy vehicle quotas can be changed back to regular quotas. New energy vehicle quotas do not require a lottery draw; you can apply for a regular passenger car quota after the electric vehicle quota expires. For users currently on the waiting list for new energy passenger car quotas under their personal name, if they switch to applying for the additional 20,000 new energy passenger car quotas allocated to car-free families but ultimately do not obtain a quota, their current waiting list position will not be affected. However, for families with multiple members participating in the waiting list or lottery, once they apply for this additional quota and ultimately obtain it, all other applications under individual names within the family will be canceled. More details are as follows: 1. According to the "Notice on the Rules for the Allocation of New Energy Passenger Car Quotas in Demonstration Applications," the annual quota for new energy passenger car quotas for individuals and units has been exhausted. Valid application codes that have passed the review will continue to be allocated according to the waiting list rules. 2. Additionally, new energy vehicle quotas can only be used to purchase models listed in the "Catalog." Since imported brands are not included in the "Recommended Models Catalog for Energy-Saving and New Energy Vehicle Demonstration and Promotion Projects" issued by the Ministry of Industry and Information Technology, they can only be purchased as traditional vehicles. 3. A separate lottery pool will be established for new energy vehicle quotas. The application conditions for individuals are basically the same as those for regular passenger car quotas, with the additional requirement of whether the buyer has the conditions to install a charging pile.

Where is the Mazda CX-5 rearview mirror heating button located?

The Mazda CX-5 rearview mirror heating switch is located on the air conditioning control panel. The rearview mirror heating button is combined with the rear windshield heating button, and the icon is a rectangle with upward airflow. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog, eliminating the need for the driver to manually wipe the mirror frequently, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass will rapidly heat up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius. The heat will dissipate from the left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface will shrink, and fog will gradually disappear, effectively heating the mirror and removing frost. However, if the rain is particularly heavy, the effect may be reduced and less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror. These wires consume a significant amount of power. When using the rearview mirror heating function, ensure the car is in a running state. Avoid activating the function while the car is stationary to prevent draining the car battery, which could leave insufficient power to start the vehicle. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open the side windows slightly to allow air flow between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting can also help by blowing warm air to defog the mirrors.

What is the mileage for the break-in period of a new car?

The break-in period for a car is generally between 1,000 to 3,000 kilometers. During this period, the owner needs to control the speed reasonably, avoiding sudden braking and rapid acceleration. It's also important to warm up the engine before starting to ensure proper lubrication, preventing unnecessary faults that could affect normal use. Precautions during the break-in period: Warm up the engine before starting; Avoid emergency braking; Avoid overloading; Do not take long-distance trips; Avoid high-speed driving; Use high-quality gasoline; Do not remove the speed limiter prematurely; Shift gears in a timely manner; Properly adjust the ignition and fuel systems. How to use the car during the break-in period: Preheat the cold engine; proper warming up allows the oil to lubricate the engine effectively, reducing wear. Shift gears promptly while driving, especially for manual transmission cars. During the break-in period, gears should be changed appropriately to avoid high gear at low RPM or low gear at high RPM. New cars should undergo timely maintenance during the break-in period.

Where is the DSC control module located in the BMW X3?

DSC stands for Dynamic Stability Control. Introduction to the DSC control module: Location of the DSC control module in the BMW X3: For older models, it is located in the engine compartment, while for newer models, it is situated on the inner side where the left front wheel arch connects with the lower guard plate. Function of the DSC control module: This system is an extension of acceleration slip regulation or traction control, ensuring optimal traction when the vehicle is turning to maintain driving stability. The DSC system is equipped with advanced detection and control features to maintain good traction during turns. It monitors wheel speed, steering wheel rotation angle, vehicle speed, and lateral acceleration. Based on this data, it determines whether there is a risk of wheel slip during a turn. If slip is detected or likely to occur, the system immediately commands the brake hydraulic control system to apply appropriate braking to the slipping wheel or reduces fuel injection and delays ignition to decrease engine power output. This prevents tire slip under various driving conditions, ensuring excellent traction during acceleration, re-acceleration, and turning.
