The tire model specification is 165/65R13. The first number 165 indicates the tire width is 165MM, 65 represents the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 13 denotes the rim diameter is 13 inches. The middle letters or symbols have special meanings: "X" indicates a high-pressure tire; "R" and "Z" indicate radial tires; "-" indicates a low-pressure tire. Maximum speed is 156km/h, and fuel consumption per 100km is 5.1L. In addition to the model, the tire also displays the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Shows the rim specification compatible with the tire for practical use, such as "Standard rim 5.00F".

Hey, while researching the Beidou Star car, I found that the original tire size is usually 165/70 R13 79T, which is quite common across many model years. The 165 indicates a tire width of 165 millimeters, 70 is the aspect ratio, meaning the tire height is 70% of the tire width, and R13 stands for radial construction with a 13-inch rim. As for 79T, 79 is the load index, capable of bearing several hundred kilograms of weight, and T is the speed rating with a maximum of 190 km/h, which is more than sufficient for an economical car like the Beidou Star. This size was chosen by the manufacturer to balance comfort, fuel efficiency, and handling—after all, smaller wheels help reduce fuel consumption. For daily driving, it's important to maintain tire pressure between 2.2-2.5 bar to ensure even wear and prolong tire life. If replacing tires, it's best not to deviate from the original 165/70 R13 size to avoid affecting the car's ABS braking or speedometer accuracy. The Beidou Star is an older model, and tires typically last around 50,000-60,000 kilometers before needing replacement—check that the tread depth doesn’t drop below 3 mm. I’ve seen many owners opt for cheaper 175/65 R14 tires, only to end up with worse handling and higher fuel consumption, which really isn’t worth it. The tire sidewalls are labeled, so keep an eye on them to avoid surprises.

What Causes Sudden Failure of Automatic Transmission Gear Shift?

Automobile automatic transmission sudden gear shift failure is caused by the gear lock being engaged, car battery power loss, etc. The following are specific introductions: Gear lock being engaged: Automatic transmission vehicles are equipped with a gear lock switch, mainly used to force gear shifting when the car has no power and cannot shift gears, or to prevent the vehicle from rolling. If this switch is accidentally touched, causing the gear to be locked, the gear shift will fail. The unlocking operation can be performed on the shift lever. Car battery power loss: Car battery power loss can also cause the inability to shift gears. You can check whether the lights and dashboard on the car are still displaying and working normally. If they are not working properly, it indicates that the car has a power loss. Simply recharge the battery to restore power.

What is the method for checking the engine oil level?

Method for checking the engine oil level: Choose a flat road surface, turn off the engine and wait for 15 minutes, then check using the dipstick. Before checking, remove the dipstick and wipe it clean with a tissue, then reinsert the dipstick until the handle is securely fixed in the guide tube. Finally, remove the dipstick, hold it horizontally, and observe the oil level. If the level is exactly at or below the "add" mark, you should add more oil. Engine oil is often referred to as the "blood" of a car, as it serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while the additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics and making them an essential part of the lubricant.

What to Do If a White Car Gets Stained by Red Cloth?

Solutions for a white car stained by red cloth: 1. Solutions: If the staining is not severe, you can use a specialized car cleaner from an auto beauty shop. Spray it on and then wipe it off. Some of these professional cleaners can even remove paint scratches, making stains easier to clean. If the staining is extensive and severe, and left untreated for a long time, you will need to go to an auto beauty shop for polishing. Avoid polishing the same car multiple times, as each polishing session will thin the paint and damage the finish. 2. White car maintenance methods: Avoid prolonged exposure to sunlight, as it can cause the car to turn yellow. The sun's ultraviolet rays are the main cause of paint yellowing. Therefore, do not let sunlight directly hit the car; it's best to park in a shaded area. Wash the car frequently, especially after rain, as rainwater and dust can easily accumulate on the car's surface. Clean it promptly, otherwise dirt will adhere to the body over time, causing the paint to turn yellow.

What is the battery model for Honda Civic car key?

The battery model is CR2032. The older Civic models use CR1616/1620 batteries, both of which are lithium manganese dioxide batteries, named according to the IEC standard. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery is cylindrical in shape, with F used for square batteries; 20 indicates the battery diameter is 20mm; 32 represents the battery height is 3.2mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity is approximately 200mAh. CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is low or quality control is poor, the lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can be extended further to 8 years or even 10 years. The usage time of a car remote key battery is closely related to the frequency of use—the more frequently it is used, the shorter the lifespan. If the remote key battery runs out, the mechanical key can be used directly to unlock and start the vehicle. Car remote keys use button batteries, mainly in models: CR2016, CR2025, CR2032, and CR2450. For the specific model used in each key, owners can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: This is one of the most commonly used car remote batteries. The battery voltage is 3V, while most car key batteries are powered by 9V, so all three batteries need to be replaced each time. Examples include Honda, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter is 20mm, thickness is 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than CR2016, but it is still used in some car keys. It is thicker than the 2016 model but has a relatively higher storage capacity. CR2025 specifications: battery diameter is 20mm, thickness is 2.5mm. This type of battery is also commonly used in audio remotes. Button battery CR2032: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically stable manganese dioxide, the negative electrode is lithium metal, and the electrolyte is a lithium battery electrolyte. The main components of the electrolyte are ethylene glycol dimethyl ether, propylene carbonate, and lithium perchlorate. It is shaped like a button, hence the name button lithium battery or lithium manganese button battery. Button battery CR2450: Compared to the other three models, it is thicker and larger, with a diameter of 24.5mm and a height of 5.0mm. The rated current value for CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, such batteries can provide an output current of 0.001mA to 5mA, with continuous output current up to 15mA and flash output current up to 30mA, meeting the requirements of most small electronic products for light emission, sound, and RF output.

What is the gear introduction of Honda Lingpai?

Gear introduction of Honda Lingpai: Gear types: The automatic transmission models of Honda Lingpai have P, N, R, D. D gear: Drive gear, press the brake, hold the side button of the gear lever, and push it backward. S gear: Sport gear, used when torque is needed. Pull the gear lever backward from the D gear position to engage the gear. To disengage the S gear, pull it backward again. (This process does not require pressing the brake) N gear: Neutral gear, press the side button with your thumb and push the gear lever forward. R gear: Reverse gear, hold the side button and continue to push the gear lever forward. P gear: Parking gear, hold the P button on the gear lever. Manual mode: On the basis of D gear, continue to move the gear lever to the side to switch to manual mode. Move the gear lever up to shift up and down to shift down. Use of paddle shifters In the "D" gear position, press the brake and push the lever to the right to switch to manual mode. At this time, you can shift up or down through the "+" and "-" paddles on the steering wheel. Although the manual mode is a bit cumbersome, it can precisely control the gear shift at the appropriate speed and torque. Gear selection for different road conditions Uphill: When going uphill, more power is needed, so you should use "D-" to downshift the vehicle to obtain high torque for climbing. Some slopes are not steep, and the gear is too low at this time, causing power waste, so you should use "D+" to upshift in time. If the power is still insufficient, you can use the S gear sport mode. Downhill: Use "D+" to shift up to D2 or D3 gear, which can restrain the engine to achieve a braking effect. Generally, 2/3 gear can meet the requirements of restraining the vehicle. When the slope is particularly steep, please use 1 gear with the brake pedal to go downhill. When you find that the vehicle is gradually accelerating downhill and cannot be controlled, use "D-" to downshift in time to enhance the effect of restraining the engine.

What is the difference between a motorcycle pushrod engine and a chain engine?

The difference between a motorcycle pushrod engine and a chain engine lies in their structure and power output. Below are the specific distinctions: Structure: A chain engine can increase speed and enhance power under the same displacement. A pushrod engine itself is not suitable for high-speed operation. To avoid the drawbacks of high speeds, it provides greater torque at medium to low speeds (commonly used range). Power Output: The simplest way for a chain engine to improve performance is by altering the cylinder diameter and stroke, which a pushrod engine cannot match. Chain engines generally focus on high-speed power output (without changing the cylinder capacity, increasing the cylinder diameter and shortening the stroke helps improve speed).
