Tire cord needs to be lubricated. The cords inside the tire are called tire cords. Related introduction: 1. Viscose cord: Fatigue-resistant, heat-resistant, and has good dimensional stability, but viscose cord has the disadvantage of being prone to moisture absorption and reduced strength after moisture absorption. Mainly used in radial passenger car tires. 2. Polyamide cord: High strength, good impact resistance and fatigue resistance, but poor dimensional stability and poor adhesion to rubber. When used, it must undergo dipping and heat stretching treatment to improve its dimensional stability and adhesion. Widely used in tires for trucks, aircraft, as well as in belts and hoses. 3. Polyester cord: High strength, large initial modulus, good thermal shrinkage and dimensional stability, but it generates high heat during fatigue, is prone to amination and hydrolysis, which reduces strength, and is difficult to bond with rubber. To improve adhesion, surface activation treatment and dipping are required. Widely used in passenger car tires. 4. Aramid cord: High strength and modulus, better high-temperature resistance and dimensional stability, but high cost and poor adhesion to rubber. Suitable for high-performance tires such as luxury cars, military vehicles, and aircraft.

As an experienced daily driver with over a decade behind the wheel, I've dealt with numerous tire retreads but never heard of applying oil to the buffed area. Tire retreading is simply adding new rubber to old tires to save money and be eco-friendly. Oil? Absolutely don't do it - oil softens rubber, makes it slippery, and can cause skidding, loss of control, or even accidents. Normally, retreading just involves cleaning, buffing, and bonding new tread with special adhesive, which already ensures a secure bond. My neighbor once foolishly applied some engine oil out of ignorance, and the next day his car felt unstable - he only felt safe after getting new tires. Remember, proper tire maintenance means regular pressure and wear checks, not using oils. This approach saves money while keeping you safe - everyone should try it.

Do motorcycle decals need to be registered?

Motorcycle decals require registration if they cover more than 30% of the body or alter the vehicle's color and shape. Details are as follows: Area must not exceed 30%: Vehicle decals should not cover more than 30% of the body surface; exceeding this requires approval. Applying stickers and decals to the vehicle body is permissible but must be done in moderation. As long as the decal area does not exceed 30% of the body, it's acceptable. If it exceeds 30% and the owner fails to report to the traffic management department of the public security bureau, the vehicle's appearance will not match the photo on the registration certificate, leading to the vehicle being classified as illegally modified. Decals must promote healthy values: Chinese law stipulates that spraying or pasting logos or advertisements on motor vehicles that affect safe driving will result in fines. For instance, some owners who seek individuality may apply highly flashy chrome decals to their vehicles. However, such decals can easily reflect light under strong illumination, potentially affecting the safety of other drivers.

What are the automotive policies?

Automotive policies refer to the 2021 new energy vehicle subsidy standards, which have been reduced by 20% compared to 2020. Below are some considerations when purchasing a used car: Pay attention to the exterior: Some used cars have been involved in accidents. To increase the value of these vehicles, dealers may refurbish and repaint them to make them look newer. Therefore, when buying a car, carefully inspect the exterior, check all corners and parts of the car for signs of repainting, and look for wear on the tires, headlights, and bumpers. Check the chassis and frame: After a car has been in an accident, even if the exterior is well repaired, the frame and chassis are difficult to restore. If you notice any deformation or bending, be cautious, as the car may have been in an accident.

Is it necessary to repair a dented car side skirt?

Whether to repair a dented car side skirt depends on the material and the extent of the damage. Below is relevant information about car maintenance: First maintenance: Some manufacturers will schedule the first maintenance based on time or mileage. The exact timing for the first maintenance should be referred to the vehicle's user manual or warranty manual. The first maintenance is very important and is usually free, so be sure to remember to do it to avoid missing it and affecting the car's third maintenance. Maintenance items: The main items of car maintenance include replacing engine oil, oil filters, transmission oil, spark plugs, air conditioning filters, air filters, brake fluid, etc. However, not all items need to be replaced every time; it depends on their service life. In addition, maintenance also involves the inspection and upkeep of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.

What is an Oil Seal Specification Chart?

An oil seal specification chart refers to specialized sealing components for general mechanical oil cylinders: USH, UPH, USI, UPI, ODI, IDI, OSI, ISI, SPG, LBH, LBI. Below is a partial introduction about SL fully synthetic engine oil: Advantages of fully synthetic engine oil: Fully synthetic engine oil uses higher-grade base oils compared to semi-synthetic engine oil. Differences in replacement intervals: Semi-synthetic engine oil requires replacement every six months or 7,500 kilometers during use, while fully synthetic engine oil requires replacement once a year or every 10,000 kilometers. Fully synthetic engine oil has a broader operating temperature range. Under the same working conditions, fully synthetic oil can protect the engine with lower viscosity, whereas semi-synthetic engine oil demands relatively higher performance requirements. Replacement interval: SL fully synthetic engine oil should be replaced once a year or every 10,000 kilometers during use.

What industry category does automotive repair belong to?

Automotive repair belongs to the service industry. Below is a detailed introduction to the relevant content: Introduction: Automotive repair is a general term for vehicle maintenance and repair, simply put, it refers to the after-sales service work of maintaining and repairing automobiles. Automotive repair involves troubleshooting faulty vehicles through technical means to identify the cause of the malfunction and taking certain measures to eliminate the fault and restore the vehicle to a certain level of performance and safety standards. According to national standards: Based on the classification requirements in the national standard "Classification of National Economic Industries," automotive repair falls under other service industries, specifically the maintenance and upkeep of automobiles and motorcycles. An auto repair shop is a specialized unit for repairing vehicles and assemblies, usually located within a bus station, but also exists as a standalone enterprise. There are two basic methods of automotive repair: on-vehicle repair and assembly exchange repair. On-vehicle repair refers to the process where, during repair, all assemblies, components, and parts removed from the vehicle that can be repaired are reinstalled onto the original vehicle after repair. Assembly exchange repair refers to a method where, except for the frame and the body itself, all other assemblies, components, and parts can be replaced using spare parts from the inventory.
