What is the size of a 16/70-20 tire?

16/70-20 tire size refers to a tire with a section width of 16 inches, an aspect ratio of 70, and a load index of 20. In the loader tire specification "16/70-20," 16 indicates the section width is 16 inches, 70 means the tire's aspect ratio is 70% (the ratio of the tire's sidewall height to its tread width), generally ranging between 30% and 80%, and the load index is 20. Tire section width refers to the maximum distance between the two outer sides of a tire when inflated to the specified pressure, typically divided in 5mm increments, though new tires have a section width tolerance of 63%. Section height is half the difference between the tire's outer diameter and the nominal rim diameter when inflated. The aspect ratio is calculated by dividing the section height by the section width and multiplying by 100. The aspect ratio on tire specifications is displayed as a percentage (with the percent sign usually omitted), commonly seen as 80, 75, 70, 65, 60, or 55. The load index represents the maximum load a single tire can bear, expressed as a code. Tire model specifications are typically marked on the tire sidewall, displaying information such as tire size, aspect ratio, tread width, etc.

Why does the engine speed fluctuate when the air conditioning is turned on?

It is due to an error in the engine control logic. Here is a detailed explanation of why the engine speed fluctuates when the air conditioning is turned on: 1. Engine control logic error: Unable to receive the signal indicating the air conditioning is turned on. When the system cannot determine whether the air conditioning is on, the engine control unit (ECU) mistakenly assumes it is a temporary high load and attempts to compensate for the idle resistance by increasing the speed. When the engine speed drops, it cannot handle the load from the air conditioning compressor, causing the speed to increase again. This results in unstable idle speed. 2. Air conditioning control circuit error: Unable to send the signal indicating the air conditioning is turned on. Similar to the first point, because the system cannot determine the air conditioning status, the ECU continuously adjusts the idle speed, leading to unstable idle. 3. Air conditioning circuit malfunction: Causes intermittent operation of the air conditioning. When the air conditioning is not working, the air conditioning compressor belt runs without load, so it does not affect the engine load. The intermittent operation of the air conditioning compressor causes the engine to continuously adjust the idle speed, resulting in unstable idle.

What are the differences between auto trading companies and 4S stores?

The differences between 4S stores and auto trading companies include variations in pricing, after-sales services, vehicle sources, storefronts, and insurance. Specific explanations are as follows: Price differences: For the same model, the base price at an auto trading company may sometimes be cheaper than at a 4S store. This is because auto trading companies are secondary dealers, sourcing their vehicles from 4S stores, essentially acting as sales agents for 4S stores. The vehicles they offer come at internal cooperative prices with 4S stores, hence the lower prices. Additionally, auto trading companies do not need to build dedicated showrooms for specific brands or invest heavily in advertising and other expenses, significantly reducing per-vehicle costs compared to 4S stores. After-sales service differences: The new automotive three-guarantee law stipulates that regardless of whether consumers purchase a car from a 4S store or an auto trading company, the seller must bear responsibility for any quality issues with the sold vehicle. If a problem arises with a car purchased from a 4S store, the store will handle it immediately. If the car was purchased from an auto trading company, the company will liaise with a 4S store for resolution. However, the after-sales maintenance services at 4S stores are generally superior to those at auto trading companies. Vehicle source differences: 4S stores source their vehicles exclusively from the original equipment manufacturers (OEMs). Each city's 4S store is an agent, qualifying to purchase vehicles from the OEM only after preliminary negotiations and payment of corresponding deposits and fees. Moreover, a 4S store can only partner with one OEM. In contrast, auto trading companies obtain their vehicles from 4S stores, without any direct connection to OEMs, which is why they are also referred to as secondary networks. Additionally, auto trading companies are not limited to partnering with just one 4S store; they often collaborate with multiple 4S stores simultaneously. Storefront differences: 4S stores are more formal, typically located in automotive sales hubs with prominent geographical advantages. Their storefronts are luxuriously decorated, with departments operating in an orderly and collaborative manner, following strict service protocols from entry to exit. Auto trading companies, on the other hand, are much more modest, with no stringent requirements on location or storefront decor, and place less emphasis on service and decoration. Insurance differences: Some auto trading companies may require car owners to purchase insurance exclusively through their partnered insurance providers, which might be small and could deny claims in the event of an accident. In contrast, 4S stores usually partner with more reliable insurance companies. Additionally, when purchasing from an auto trading company, consider the following: Auto trading companies issue invoices through 4S stores: Since auto trading companies source their vehicles from 4S stores, they are treated as regular consumers by the 4S stores. Therefore, when an auto trading company purchases a vehicle from a 4S store, it must pay upfront before taking delivery. At the time of payment, the auto trading company will issue the purchase invoice in the customer's name, similar to having a friend purchase a car on your behalf from a 4S store, which is recognized by the 4S store. Normal warranty coverage: Regardless of where you buy the car, as long as you have a valid purchase invoice, the vehicle is eligible for the standard warranty starting from the invoice date. Most cars now come with relatively long warranty periods, ranging from three or four years to ten years or more, with some even offering lifetime warranties. Signing a purchase contract: Most auto trading companies will sign a purchase contract with the customer, detailing the model, price, color, and configuration. When signing the contract, customers can make specific requests, such as ensuring the vehicle is undamaged or not from stock, and have these terms noted in the contract. This provides a basis for recourse should any issues arise later. Financing: If you opt for financing, it's advisable to go through the manufacturer's financial services offered by the auto trading company. Manufacturer financing serves as a primary purchase credential, typically involving lower unnecessary fees and more favorable interest rates compared to banks. Financing through a bank or private lender partnered with the auto trading company may incur significantly higher fees and taxes. Choosing a reputable auto trading company: A reputable auto trading company should have a long-standing presence, good reputation, many repeat customers, and comprehensive information.

Is the 175-75r14c tire highly load-bearing?

The 175-75r14c tire has a high load-bearing capacity, as the letter 'c' at the end indicates that it is a reinforced tire. The preceding numbers and letters denote the tire's specifications. Here, 175 represents the tire's cross-sectional width of 175mm, 75 indicates the aspect ratio of 75%, 'r' signifies that the tire has a radial structure, and 14 means the tire is suitable for a rim diameter of 14 inches. Below is a detailed introduction to the 175-75r14c tire: Both LT (Light Truck) tires and C tires are light-duty load-bearing tires. These tires are thicker, harder, and more capable of carrying heavy loads. They tend to have more pronounced tire vibration, noticeable road noise, poorer comfort, and inferior highway performance. Some tires have arrows or the word 'OUTERSIDE' marked on the sidewall, indicating the tire's rotation direction. If a small umbrella symbol is depicted on the sidewall, it means the tire is suitable for driving in rainy or slippery conditions. The meanings of the letters on tires are as follows: 'X' stands for high-pressure tire; 'C' stands for reinforced; 'B' stands for bias-ply tire; '-' stands for low-pressure tire. 'M' and 'S' are abbreviations for Mud and Snow, respectively, indicating that the tire is suitable for use on snowy and muddy roads.

What are the reasons why a Citroen C5 won't start?

The reasons and solutions for a Citroen C5 failing to start are as follows: 1. Insufficient battery power or low fuel level: This is the easiest item to check and the most likely cause of a car not starting. Turn the ignition key to the ON position (for push-button start models, press the start button twice without pressing the brake pedal), turn on the headlights, and observe if the lights noticeably dim or fail to illuminate. Then press the horn; if the sound is significantly weaker than usual or doesn't sound at all, it can be determined that the battery power is insufficient. In either of these situations, the owner can seek assistance from nearby drivers for emergency measures such as jump-starting, borrowing fuel, or towing. 2. Steering wheel lock preventing startup: This is a common anti-theft feature in many cars. After removing the key, if the steering wheel isn't straightened or is turned, the self-locking function activates, causing the steering lock pin to engage with the steering column, making the steering wheel immobile and preventing the car from starting. The solution is simple: jiggle the steering wheel while turning the key. Otherwise, even breaking the key won't make it turn. 3. Wrong gear selection: Check the car's gear position. Normally, the P or N gear is the correct position for starting an automatic transmission car. If the owner carelessly leaves the gear in R or another position, not only will the car fail to start, but it also poses a safety hazard. The solution is to adjust to the correct gear and then attempt to start the car.
