The manufacturing year of a car tire is printed on the tire sidewall near the rim, represented by 4 digits. The first two digits indicate the production week, and the last two digits indicate the production year. How to check the tire manufacturing year: There is usually a DOT mark embossed on one side of the tire. The last four digits after this mark indicate the production date information, consisting of four digits "AABB". The first two digits "AA" represent the week of the year, while the last two digits "BB" represent the year. Precautions for car tires: Tires with cracks should be replaced immediately. If the crack length is less than 6mm and hasn't damaged the internal cord material, it can be repaired at a shop without immediate replacement. However, if the damage is too large or the sidewall is already broken, the tire should be replaced as soon as possible. If you feel it's wasteful to discard the replaced tire, it can be repaired and used temporarily as a spare tire. The four tires of a family car are generally of the same brand and specification to ensure optimal vehicle performance. If the four tires have inconsistent sizes, structures, or wear patterns, it will affect the vehicle's handling and stability. Therefore, when tires show significant wear and one needs replacement, it's best to replace all four tires simultaneously.

Having driven for over a decade, I know exactly where to find the tire's manufacturing date: it's in the small-print DOT code on the tire's sidewall. The last four digits indicate the production date—the first two represent the week, and the last two the year. For example, '2519' means the tire was made in the 25th week of 2019. Why does this matter? Aged tires are prone to cracks or blowouts, especially during hot summer months when risks are higher. I inspect mine every six months to ensure none are older than 8 years. A quick squat to glance at the sidewall while parking can prevent safety hazards. If tires are too old, it's best to replace them—don't skimp on safety; it should always come first!

What are the differences between China IV and China V standards?

The differences between China IV and China V standards lie in their sulfur content limits: China IV standard gasoline has a sulfur content limit of 10mg, while China V standard gasoline has a sulfur content limit of 50mg. The details are as follows: 1. China V: It imposes stricter controls on nitrogen oxides compared to China IV, with China V setting the emission limit at 25%. 2. China IV: The China IV emission standard is the fourth stage of China's motor vehicle pollutant emission standards. The main pollutants emitted by vehicles include HC, NOx, CO, PM, etc. Technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices are applied to reduce these emissions.

They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing the vehicle's driving performance. 2. Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

What to Do When There Is Occasional Shaking at Idle Speed?

Minor shaking at idle speed is a normal phenomenon, as the engine will produce vibrations during operation. However, if the shaking is excessive or violent, it is necessary to check whether the vehicle has developed a fault. Body shaking at idle is a common situation encountered by many car owners. Relevant information about idle speed is as follows: 1. Introduction: Idle speed is an operating condition of a car, referring to the engine running in neutral gear. The engine speed at idle is called the idle speed. The idle speed can be adjusted by changing the throttle opening size, among other methods. Idle speed means the engine is 'working but not performing labor.' 2. Driving Idle: When the car is in gear, without pressing the accelerator pedal or releasing it during driving, maintaining the minimum throttle opening, the engine speed matches the parked idle speed. This state is referred to as driving idle.
