What brand is yeada tire?

yeada is Yida Tire, a new high-end brand under Shandong Fengyuan Tire Manufacturing Co., Ltd. Shandong Fengyuan Tire Manufacturing Co., Ltd. is located in Yicheng Economic Development Zone, Zaozhuang City, Shandong Province, covering an area of 628 acres. The company is state-owned by Zaozhuang Mining Group, a subsidiary of Shandong Energy (a Fortune 500 company), and is a modern large-scale enterprise integrating the R&D, manufacturing, and sales of semi-steel radial tires. It has a professional technical R&D team and a laboratory. Tires are rubber products, and rubber products will age after prolonged use, so tires need to be replaced regularly. When purchasing new tires, be sure to check the production date, as tires have a shelf life. Under normal circumstances, the shelf life of unused tires is three years. If the tires have been in storage for more than three years, do not purchase them. If abnormal wheel vibration occurs during high-speed driving, it will affect the vehicle's handling and driving stability. Regularly check the tire pressure, as it is crucial for tires. The tire pressure should not be too high or too low. If the pressure is too high, it will reduce the tire's grip, affecting the vehicle's handling. If the pressure is too low, it may cause wave-like deformation of the tire. Tips for selecting tires: First, prioritize original equipment (OE) tires. OE tires are designed to match the vehicle's speed and maximum load capacity, so theoretically, they should be the first choice when replacing tires. Second, pay attention to the tire tread pattern. The tread pattern on tires not only enhances aesthetics but also significantly impacts tire performance. For vehicles frequently driven in Shenzhen, choose tires with good drainage patterns, such as those with regular small block patterns. For off-road or long-distance driving, opt for tires with larger block patterns. Tires and the vehicle's suspension system work together to absorb shocks during driving, providing good ride comfort and smoothness while ensuring strong adhesion between the wheels and the road. Tires bear the weight of the vehicle and are one of the most important components of a car. Characteristics of car tires: The tread of car tires features patterns that enhance performance, and the cross-section width is increased. Lower internal pressure is used to improve cushioning performance. Car tires can be categorized into radial tires and bias-ply tires based on structure. Precautions for tire storage: Tires should be stored in a warehouse that is dry, well-ventilated, and protected from direct sunlight. Keep tires away from heat sources, electrical equipment, and ozone-producing areas. Do not store tires with oil, flammable materials, or corrosive chemicals. Outer tires or complete tires should be stored upright; flat stacking or hanging through the center is prohibited. Large tires must be stored upright in a single layer, while medium and small tires can be stored upright in two layers. Rotate the tires every two months. If inner tubes are stored separately, inflate them with an appropriate amount of air. When hung on a semi-circular wooden rack, rotate the support points periodically and avoid folding or stacking them flat. Tips for selecting tires: Choose new tires with the same size as the original tires. If you enjoy aggressive driving, tires will wear out faster, so opt for durable tires. For national highways or expressway driving: Braking distance at high speeds: For maximum safety, choose tires with the shortest braking distance on both dry and wet roads. Comfort: For long-distance travel, select tires that provide a comfortable ride (with minimal bumps and noise). Performance: Opt for high-performance tires. For city driving: Braking distance: To handle various urban hazards (such as pedestrians crossing the road), choose tires with the shortest braking distance on both dry and wet roads. Long mileage life: The tread blocks of tires in contact with the road will deform and slide due to engine power or braking force. Sliding and friction wear down the tread rubber, so choose tires with a longer mileage life. Fuel economy: Tires with lower rolling resistance can significantly reduce fuel consumption. For yeada tires, pay attention to the following during daily use: Regularly inspect the tire surface for cracks, deformations, or other defects. As tires wear, the tread grooves gradually become shallower. If the tread is worn flat, it will lose its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks may pose a risk of blowouts during high-speed driving. Additionally, promptly remove small stones stuck in the grooves. Park on flat ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that degrade rubber. After parking, do not turn the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires can overheat, and the pressure may increase. In such cases, park to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear due to dragging between the tires and the road.

Can full synthetic engine oil last for one year?

The recommended replacement interval for full synthetic engine oil is approximately one year or 10,000 kilometers. Relevant information is as follows: 1. Long lifespan: Currently, common full synthetic oils on the market are made from Group III base oils through hydrogenation. Full synthetic oil is superior to conventional mineral oil and semi-synthetic oil, offering better stability, oxidation resistance, and corrosion resistance, which naturally results in a longer service life. Generally, it should be replaced once a year or after driving about 10,000 kilometers. Therefore, if your car uses full synthetic oil, using it for a year is generally not a problem. 2. Superior performance: Due to the superior performance of full synthetic oil, it is suitable for high-end vehicles or those requiring higher performance. For economical family cars with regular oil maintenance, semi-synthetic oil may be more appropriate. Full synthetic oil is not suitable for all vehicles. Older vehicles with long service times are recommended to use semi-synthetic oil because these older cars have relatively poorer sealing. Full synthetic oil, with its low viscosity and good fluidity, may be more prone to leakage, making higher viscosity semi-synthetic oil a more suitable choice.

Why Do Motorcycles Easily Stall in the Rain?

Common reasons why motorcycles easily stall in the rain include: water ingress causing short circuits in the ignition switch or right-hand kill switch, poor waterproofing of the ignition system's high-voltage cap leading to water ingress, or the overflow tube at the bottom of the carburetor being too long, causing water droplets to be sucked into the carburetor due to negative pressure, resulting in stalling. Precautions for riding a motorcycle in the rain are as follows: 1. Wear a helmet correctly: Always wear a helmet when riding in the rain, but avoid covering the helmet with a raincoat as it can obstruct vision and hinder head movement, making riding difficult. Riders who wear glasses should opt for a helmet with a windshield to prevent rain from wetting their eyes and blurring vision. If water accumulates on the helmet's windshield, simply wipe it off with your hand. 2. Navigating through waterlogged roads: Some roads may have large puddles due to poor drainage or low-lying areas. When encountering such conditions, first assess the water depth, which should be below the height of the spark plug and exhaust pipe to ensure the vehicle doesn't stall while passing through. If the motorcycle stalls and cannot be restarted, push it to a safe area and dry the spark plug and high-voltage cap.

What does high-pressure common rail in diesel engines mean?

High-pressure common rail technology refers to a fuel supply method in a closed-loop system composed of a high-pressure fuel pump, pressure sensor, and ECU, where the generation of injection pressure and the injection process are completely separated. The high-pressure fuel pump delivers high-pressure fuel to a common fuel rail, and precise control is achieved over the fuel pressure within the common rail. Advantages: 1. Flexible adjustment of injection pressure in the high-pressure common rail system: The optimal injection pressure required for different operating conditions can be determined, thereby optimizing the overall performance of the diesel engine. 2. Independent and flexible control of injection timing: Combined with high injection pressure (120MPa to 200MPa), it can simultaneously control NOx and particulate matter (PM) at lower levels to meet emission requirements. 3. Flexible control of injection rate changes: Achieves ideal injection patterns, easily enabling pre-injection and multiple injections, which can reduce NOx emissions while ensuring excellent power and fuel economy. 4. Electromagnetic valve-controlled injectors: High control precision prevents air bubbles and residual pressure in the high-pressure fuel lines, ensuring minimal variation in cyclic fuel injection across the engine's operating range, improving fuel supply uniformity among cylinders, thereby reducing engine vibration and lowering emissions.

What Are the Causes of Steering Wheel Noise When Turning in Winter?

The main causes of noise when turning the steering wheel include insufficient lubrication of the steering column, excessive friction, lack of power steering fluid; universal joint failure; aging of the suspension stabilizer bar bushings; and failure of the thrust bearing. If the steering column has excessive friction, power steering fluid should be added promptly. The steering column is a type of steering column locking device, primarily composed of a lock rod, camshaft, lock stopper, unlock lever, and unlock button. If the universal joint fails, it can alter the vertical bouncing angle and should be replaced immediately; otherwise, it may prevent the car from operating normally. Its function is to accommodate power transmission, steering, and the angle changes caused by vertical bouncing during vehicle operation. Aged suspension stabilizer bar bushings should be replaced promptly, and regular inspections of these components should be conducted to prevent failures. Thrust bearing failure can cause the vehicle to pull to one side, so pressurization or depressurization treatment is required, which should be performed at a repair shop. The automotive thrust bearing, also known as the pressure bearing, withstands vertical pressure and allows free rotation.
