It is not normal to buy 2019 tires in 2021. Tires that have been in storage for over a year are considered stock tires. Tires that have been in storage for three years are expired, as the rubber has aged, significantly reducing comfort and making them prone to cracking and poor heat dissipation. This greatly impacts both acceleration and braking, and increases the risk of blowouts at high speeds, seriously endangering the safety of the vehicle owner's life and property. Purchasing such tires is absolutely prohibited. Below is relevant information about tires: 1. Check the tire's expiration date: The sidewall of the tire will have a four-digit number indicating the manufacturing date, with the first two digits representing the week and the last two representing the year. Generally, tires should not be used for more than three years or exceed 60,000 kilometers in mileage. 2. Pay attention to the sidewall: As the tire rubber ages, deep cracks may appear on the sidewall. However, as long as the sidewall has not been impacted and the cords are not broken, the tire can still be used. The triangular mark on the tire sidewall can help the owner locate a protrusion in the tread groove, which indicates the actual wear limit of the tire. That value should be greater than 1.6 millimeters.

What does the car microwave window mean?

Car microwave window is a designated area for placing electronic tags, typically located at the upper right center of the front windshield. Generally, the car microwave window should not be obstructed by brackets such as rain sensors or lane departure warning systems, with center wavelengths of 1.4mm, 3.3mm, and 8mm respectively. Currently, microwave windows have been widely adopted, where side-view radars primarily utilize windows with wavelengths greater than 0.5cm and the 8mm window, while the 1.4mm and 3.3mm windows are mainly used for satellite communication and missile tracking. According to European standards, automakers must reserve a metal-ion-free microwave window measuring at least 120mm in length and 70mm in width behind the rearview mirror on the upper part of the front windshield, exclusively for electronic tag use.

What Causes Loud Throttle Noise and How to Solve It?

The causes and solutions for loud throttle noise: The throttle is either too dirty or damaged. It is recommended to clean the carbon buildup on the throttle or replace the throttle. The car's throttle is generally located at the engine intake, behind the engine air filter and in front of the intake manifold. The main function of the throttle is to control the amount of air intake, which in turn affects the amount of fuel injection. An increase in air intake leads to an increase in fuel injection. After a period of use, both the throttle and fuel injectors can become dirty. A dirty throttle or fuel injectors can result in symptoms such as weak acceleration, loud noise, increased fuel consumption, and engine shaking. Therefore, regular cleaning is necessary, but it does not mean that the more frequently the throttle and fuel injectors are cleaned, the better.
