How to Check the Production Date of Michelin Tires?

Method to check the production date of Michelin tires: Locate the DOT marking on the sidewall of the tire. The last four digits following this marking represent the production date of the Michelin tire. The first two digits indicate the week of production within the year, and the last two digits indicate the production year. Below is an introduction to the functions of car tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; work together with the car suspension to mitigate impacts during driving and dampen the resulting vibrations. 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency.

What is the Scrap Age for Most Vehicles?

Non-commercial vehicles and commercial vehicles have different scrap ages, as detailed below: Scrap Regulations for Non-commercial Vehicles: For 5-seat family cars and 7-seat SUVs, as well as small and micro non-commercial vehicles, there is no usage age limit. However, when the mileage reaches 600,000 kilometers under normal driving conditions, the state will guide the vehicle to be scrapped. In addition to the above vehicles, small and micro non-commercial passenger vehicles, large non-commercial cars, and wheeled special machinery vehicles also have no usage age limit. Common Scrap Regulations for Commercial Vehicles: Small and micro taxi passenger vehicles have a scrap age of 8 years, medium-sized taxi passenger vehicles have a scrap age of 10 years, and large taxi passenger vehicles have a scrap age of 12 years. Public transport passenger vehicles have a scrap age of 13 years, other small and micro commercial passenger vehicles have a scrap age of 10 years, and large and medium-sized commercial passenger vehicles have a scrap age of 15 years. Micro commercial trucks have a scrap age of 8 years, while light and large commercial trucks have a scrap age of 10 years. The vehicle scrapping process is as follows: The vehicle owner applying for scrapping and renewal must fill out the "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix their seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrap age. For vehicles that have not reached the scrap age, the vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if applicable. The vehicle owner can choose a qualified recycling company to dismantle the vehicle based on the "Notice." The recycling company will dismantle the vehicle and take photos after verifying the "Notice." The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner must submit the "Modification Form," "XX Province Vehicle Renewal Technical Appraisal Form," "Scrapped Vehicle Recycling Certificate," and photos of the dismantled vehicle to the vehicle inspection office for verification and signature. The license plates will be reclaimed, and the scrapping registration will be processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations," if a vehicle cannot be driven back to its registered location due to damage, the owner may sell the scrapped vehicle to a local recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must still be scrapped according to the original commercial vehicle's scrap age. According to Article 43 of the "Motor Vehicle Registration Regulations," after completing the transfer or cancellation of a vehicle's registration, the original owner may apply to the vehicle management office to use the original license plate number for a newly purchased vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation; (2) The owner must have owned the original vehicle for at least three years.

What does 4WS mean in cars?

4WS in cars is the abbreviation of Four-Wheel-Steer, known as the four-wheel steering system, also referred to as rear-wheel steering or four-wheel steering. The four-wheel steering system is a patented technology of the Fukang model, earning it the nickname "King of Corners" due to this technology. Here is an introduction to the four-wheel steering system: 1. There are mainly two types of four-wheel steering: same-phase steering, where the rear wheels steer in the same direction as the front wheels; and opposite-phase steering, where the rear wheels steer in the opposite direction to the front wheels. 2. The purpose is to improve the operational stability of the car at high speeds or under lateral wind forces, enhance maneuverability at low speeds, and reduce the turning radius in parking lots.

What to Do When the Engine Makes Abnormal Noises While Driving?

When the engine makes abnormal noises while driving, it is recommended to promptly visit a 4S shop or a professional auto repair shop for inspection by maintenance personnel. Only by identifying the source of the problem can targeted repairs be made. Abnormal engine noises in cars can be categorized into many types, such as noises during rapid acceleration, cold starts, or idling. Each situation requires distinct analysis. Below are common causes of abnormal engine noises in cars: 1. The phenomenon of engine knocking is characterized by a "clanging" sound, mainly caused by the collision between the piston skirt and the cylinder wall during engine operation, often due to poor lubrication conditions. The solution is to replace the engine's four supporting components. 2. Abnormal noises in the intake and exhaust systems, such as intake manifold leaks, manifest as noises during idle operation, which intensify with increased engine speed. 3. A "hissing" noise from the engine is likely due to issues in the cooling system, leading to engine overheating. 4. A "squeaking" noise from the engine, especially more noticeable when the air conditioning is on, is probably due to the engine belt slipping. 5. A "clicking" noise from the engine is likely caused by engine carbon deposits, and it is advisable to use higher-grade gasoline.

What does the wrench symbol mean when it appears on a car?

The wrench symbol appearing on a car's dashboard indicates that the vehicle has reached its scheduled maintenance interval. The maintenance cycle is preset during manufacturing to remind drivers to perform timely maintenance. Typically, 4S dealerships recommend performing routine maintenance every 5,000 kilometers or every six months. Basic maintenance items usually include changing the engine oil, oil filter, and air filter. Below is an introduction to car maintenance: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle servicing. 2. Modern car maintenance primarily includes servicing the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. 3. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards to prevent failures, slow down the deterioration process, and extend the vehicle's lifespan.

What is the difference between 195 and 205 tires?

195 vs 205 tire differences: 1. Different tire sizes: The diameter of a 195 tire is 634.5mm, while a 205 tire has a diameter of 631.9mm, making the 195 tire 2.6mm taller than the 205. 2. Different aspect ratios: At the same tire height, the 205 has a lower aspect ratio than the 195, meaning better handling performance. 3. Different contact areas: The 205 tire is 10mm wider than the 195, with approximately 5% more rolling resistance. At low speeds without considering wind resistance, the 205 naturally consumes about 5% more fuel than the 195.
