3.00-10 tire means a tire with a width of 3 inches and a diameter of 10 inches. 3.00 represents the width of the tire in inches, where one inch equals 2.54 cm, so 3.00 is 7.62 cm. The 10 refers to the diameter of the tire, generally indicating a diameter of 25.4 cm. Tires are the most important components of a vehicle, and their main functions include: supporting the entire weight of the vehicle and bearing the load; transmitting traction and braking torque to ensure adhesion between the wheels and the road; reducing and absorbing vibrations and impact forces during driving to prevent severe vibrations and early damage to vehicle components; adapting to the high-speed performance of the vehicle and reducing noise during driving, ensuring safety, handling stability, comfort, and fuel efficiency. The international standard tire code expresses the section width and aspect ratio as a percentage in millimeters. It is followed by: tire type code, rim diameter (in inches), load index (permissible load mass code), and permissible speed code. For example, in 175/70R14 77H, 175 represents a tire width of 175 mm, 70 indicates the aspect ratio of the tire's section is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the speed rating is H.

How to Check the Manufacturing Date of Car Tires?

The method to check the manufacturing date of car tires: Usually, the sidewall of the tire will have a manufacturing date identifier, typically a series of alphanumeric characters starting with DOT. DOT stands for the certification by the U.S. Department of Transportation, followed by numbers and letters representing the tire's origin information and factory code. The last four digits indicate the manufacturing date. The first two digits represent the production week, and the last two digits represent the production year. Besides the manufacturing date identifier, the tire sidewall may also display markings like 225/45R17, 91W, which correspond to the tire width, aspect ratio, tire type, rim diameter, load index, and speed rating. 225 indicates the tire width is 225mm, 45 means the aspect ratio is 45%, R denotes a radial tire, 17 signifies that it fits a 17-inch wheel, 91 represents a load index of 615kg, and W indicates the maximum speed the tire can handle is 270km/h.

Is Soueast Motors a Domestic Car?

Soueast Motors is a domestic car and also a joint venture brand. Domestic cars and independent brand cars are two completely different concepts. Many people confuse the concept of independent brands with domestic cars, thinking that only independent brands can be considered domestic cars, such as Great Wall Motors. Domestic cars can be understood as any car produced in mainland China being called a domestic car. For example, BMW Brilliance and Beijing Benz are joint venture brands but are also domestic cars. Soueast Motor Co., Ltd., abbreviated as Soueast Motors, was jointly established by Fujian Motor Industry Group Co., Ltd. and China Motor Corporation, a subsidiary of Taiwan's Yulon Group. Soueast brands include: Delica, Freeca, Lancer, Veryca, Soueast C1, V3 Lingyue, V5 Lingzhi, and V6 Lingshi. Taking the V6 Lingshi as an example, it is the first compact hatchback launched by Soueast, with a length, width, and height of 4475mm, 1770mm, and 1475mm respectively, and a wheelbase of 2610mm.

How Long Does It Take to Service a Car?

The service interval for a car is typically every 5,000 kilometers or 10,000 kilometers, depending on the effective duration or mileage of the engine oil and oil filter used. Vehicle maintenance is divided into minor and major services. A "minor service" mainly includes changing the engine oil and oil filter, along with routine inspections. A "major service" is more comprehensive than a minor service. In addition to changing the engine oil and oil filter, it usually involves replacing the air filter and fuel filter. Depending on the vehicle's usage, it may also require replacing critical components such as brake fluid, antifreeze, transmission fluid, spark plugs, engine timing belts, engine coolant, power steering fluid, brakes, battery, tires, etc. The car engine requires lubrication, but as the vehicle is driven, the base oil and additives in the engine oil can deteriorate and become ineffective. Therefore, to protect the engine, it is necessary to change the oil regularly. Even if the car hasn't been driven much, such routine maintenance is essential to ensure optimal vehicle performance.

How to Determine When to Replace Car Spark Plugs?

Signs that spark plugs need replacement primarily include noticeably high fuel consumption and sluggish vehicle performance with unresponsive throttle. 1. Difficult ignition. Whether during cold or warm starts, achieving instant ignition becomes nearly impossible—even successful starts take 5-6 seconds. This occurs because the spark plug electrodes are severely worn, with rounded edges around the center electrode resulting in weak, unstable spark discharge. Additionally, excessive spark plug gap reduces spark intensity and penetration power, making it difficult to ignite the air-fuel mixture. 2. Increased fuel consumption. Normal consumption of 7-8L/100km may suddenly rise to over 10L. The exhaust emits unburned fuel droplets (sounding like falling metal beads), requiring more frequent refueling. 3. Noticeable power loss during hill climbs or sudden acceleration. Especially when carrying passengers, full throttle fails to deliver expected power. This happens because degraded spark plug performance increases misfire rates, causing incomplete combustion of the air-fuel mixture before exhaust. The engine cannot achieve its designed maximum power output, resulting in throttle lag. Spark plug replacement intervals: Under normal maintenance conditions, replacement is recommended at 40,000-60,000 km. However, this varies by brand and engine type—always consult your owner's manual. General replacement guidelines: • Platinum spark plugs: 40,000 km • Standard nickel alloy spark plugs: 20,000 km • Iridium spark plugs: 60,000-80,000 km
