Looking at this set of tire codes 195/55R15-85V, it's somewhat like a car's ID card. 195 refers to the tire width of 195 millimeters—the larger the number, the wider the tire, providing stronger grip but potentially higher fuel consumption. 55 is the aspect ratio percentage, meaning the tire sidewall height is 55% of the width. A lower value means a flatter tire, offering better handling but a bumpier ride, while a higher value improves comfort but slows down cornering. R stands for radial construction, the mainstream design today, which is more durable and stable. 15 indicates the rim diameter of 15 inches, which must match your car's wheel size. 85 is the load index, representing a maximum load capacity of around 515 kg per tire—choosing the wrong one may lead to overloading and damage. V is the speed rating, with an upper limit of 240 km/h—make sure your tires meet this before high-speed driving. As someone who often works on car modifications, I must strictly align these parameters with the manufacturer's recommendations. Otherwise, acceleration becomes unstable, and tire lifespan shortens. When replacing tires, checking the original car manual is the easiest way to ensure compatibility.

What Causes Knocking Sounds from the Chassis After the Car Shuts Off?

Car chassis noises after shutdown can be attributed to the following reasons: Cooling sounds from the catalytic converter: The normal operating temperature of a catalytic converter ranges between 400-800°C. After shutdown, its operation gradually stops, and the temperature decreases, causing the internal metal components to expand and contract due to heat, resulting in abnormal noises. Cooling sounds from the exhaust pipe: Typically, the exhaust pipe can reach temperatures above 200°C during cold idle. When the car is under high load or there is combustion of the air-fuel mixture in the exhaust pipe, the temperature can rise even higher. Consequently, the exhaust pipe also undergoes thermal expansion and contraction, producing abnormal noises, often originating from the front end or flexible joint of the exhaust pipe. Turbo cooling sounds: Under normal conditions, the exhaust gas temperature can reach 600-700°C, accelerating the friction-induced heat from the rapidly spinning turbo. After shutdown, the thermal expansion and contraction become quite noticeable, leading to abnormal noises.

How Deep of Water Can a Car Drive Through?

How deep of water a car can drive through depends on the specific conditions of the vehicle itself. Below are the reference standards for judgment: Exhaust pipe height: Safe wading depth. The pressure generated by the engine exhaust is strong enough to expel water that might backflow into the exhaust pipe. Therefore, as long as the engine does not stall and the vehicle maintains sufficient and stable power, it can prevent water from backflowing into the exhaust pipe, allowing safe passage through water at this level. Bottom edge of the door height: May cause water to enter the cabin. Modern cars are equipped with various electronic components and sensors. Although current cars have good waterproofing and generally do not leak unless submerged for extended periods, if the sealing strips are aged, water may seep in. Air intake height: Maximum wading depth. The height of the engine air intake is the most critical indicator of a vehicle's wading capability. If water enters the air intake, it can cause the engine to stall, and in severe cases, water can be sucked into the engine, leading to permanent damage. Therefore, driving is absolutely not advisable if the water reaches this level.

What is the difference between CH and CF engine oils?

Differences between CH and CF engine oils: Different application ranges: CF is suitable for high-speed, four-stroke, naturally aspirated or turbocharged diesel engines; CH is used for high-speed, four-stroke diesel engines that comply with the 1998 US emission standards and use fuel with sulfur content below 0.5%. Different grades: CH has a higher grade than CF. Different performance: CH-grade engine oil performs better than CF-grade. Different emission standards: CH-4 has higher tailpipe emission standards than CF-4. Different prices: CH engine oil is more expensive than CF engine oil. Different application ranges: CF is suitable for high-speed, four-stroke, naturally aspirated or turbocharged diesel engines; CH is used for high-speed, four-stroke diesel engines. Engine oil is an item that every car owner comes into contact with during vehicle usage. Inside the engine, it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. It is known as the 'blood' of a car. Engine oil consists of base oil and additives. Over time, every performance aspect of engine oil degrades, necessitating regular replacement. Prolonged failure to change engine oil can accelerate engine wear. When selecting engine oil, consider the following: Choose engine oil based on the engine's requirements. There's no need to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands. Preferably choose multi-grade oil. Multi-grade oil is economical, long-lasting, and efficient, offering better protection for the engine. Due to its characteristics, multi-grade oil may appear darker prematurely and exhibit lower oil pressure compared to conventional oils, which is normal.

Should the Corolla 1.2T use 92 or 95 octane gasoline?

The Corolla 1.2T's gasoline standard is 92 octane. Some Japanese turbocharged engines have special anti-knock designs that allow the engine to use lower-octane gasoline to reduce operating costs. Difference between 92 and 95 octane gasoline: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The gasoline octane rating represents the fuel's anti-knock performance. The higher the octane number, the better the anti-knock performance. However, the octane rating has no relation to the quality of the gasoline itself. A higher octane number does not mean the gasoline is better, nor does it mean the gasoline has fewer impurities or is purer. The octane number precisely serves the purpose of gasoline's anti-knock performance. The higher the octane number, the stronger the anti-knock performance. The higher the compression ratio, the higher the pressure in the combustion chamber. If gasoline with lower anti-knock performance is used, knocking is more likely to occur. Since 95 octane gasoline has a higher octane content than 92 octane, its anti-knock performance is better. The choice of gasoline octane rating should be based on the engine's compression ratio. Do not blindly use higher-octane fuel. If the car's compression ratio is insufficient, the advantage of the gasoline's high anti-knock performance cannot be utilized. Instead, using gasoline that does not match the compression ratio may cause the gasoline mixture to detonate prematurely during the engine piston's compression stroke, affecting the car's power.

Can a Car Be Transferred Without the Nameplate?

If the car's nameplate is torn off, it cannot be transferred normally. More relevant information is as follows: When inspecting the car: You should check whether the vehicle's procedures are complete and ensure that the car can be transferred normally. If the vehicle's procedures are incomplete and cannot be transferred normally, then there is no need to inspect the car or discuss the price. After confirming the vehicle's procedures, do not rush to negotiate the price; instead, check the condition of the vehicle. When inspecting the vehicle's condition: You should check whether the car has been involved in any serious accidents, whether it has been flooded or burned, and also verify the actual mileage of the vehicle. In some used car markets, there are many vehicles with tampered odometers. Many used car dealers adjust the mileage of high-mileage cars to make them appear low-mileage, so extra caution is needed when purchasing such vehicles. If the car's interior is severely worn and the tires have been replaced multiple times, but the vehicle's mileage is very low, then special attention is required. When checking whether the car has been involved in any serious accidents, you should also inspect whether the vehicle's frame has been repaired.
