The number 98 in 98W on a tire represents the load index, where 98 corresponds to a maximum load capacity of 750KG per tire; the letter W stands for the speed rating, indicating a maximum speed of 270km/h. The load index is molded on the sidewall of the tire, representing the maximum load limit for that tire. For driving safety, this load limit should not be exceeded, as overloading may cause excessive heat buildup and lead to sudden tire failure. Definition of tire load index: It refers to the maximum load a tire can carry when inflated to the specified pressure. It is usually represented by a numerical value. Definition of tire speed rating: It refers to the maximum speed at which a tire is allowed to operate, generally indicated by a capital letter and marked on the sidewall of the tire. In addition to the model, the following common data are also marked on the tire: Tire cord material: Represented by Chinese Pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tire. Speed rating: Indicates the maximum speed at which a tire can carry a specified load under specified conditions. Letters from A to Z represent certified speed ratings ranging from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h.

Below is a relevant introduction to the Wuling Hongguang Plus: 1. Exterior Design: The Wuling Hongguang PLUS adopts the design elements of "parallel rectangles, simple and rugged," along with the design concept of "micro-curved" body surfaces. The combination of various parallel straight lines and broken lines resonates with the overall design style, advocating simplicity and the idea of reducing complexity. 2. Interior Design: The interior design of the Wuling Hongguang PLUS organically combines various modules with parallel and smooth lines, paired with classic tones of beige, black, and gray. The minimalist and rugged interior atmosphere with a sense of design creates a "parallel space wide-body cockpit," delivering a simple and reliable visual effect. 3. Powertrain: The Wuling Hongguang PLUS is equipped with a 1.5T turbocharged engine across all variants, paired with a 6MT manual transmission. It delivers a maximum torque of 250N·m, which can be achieved at 2200rpm, equivalent to the maximum torque produced by mainstream 2.4L engines. The strong low-end torque ensures easy starts and significantly enhances climbing and load-carrying capabilities, fully meeting users' daily commuting and heavy-load transportation needs.

What Causes Abnormal Noises When a Car Turns?

When a car makes abnormal noises while turning, the possible reasons are as follows: 1. Friction between plastic components. 2. Friction between the steering column and the floor mat. 3. Malfunction of the clock spring inside the steering wheel. 4. Aging or excessive play in the steering tie rod ball joint. 5. Excessive gear clearance in the steering gear. Below is more information about the car: 1. The steering wheel is composed of various plastic parts. If the gaps are too small, abnormal noises may occur, especially in new cars, which usually resolve after a break-in period. 2. If the noise persists after the break-in period, try reinstalling the steering wheel. If the floor mat is too large and comes into direct contact with the steering column, friction will occur when the steering column rotates, producing noise. This is a common issue and can be resolved by adjusting or replacing the floor mat. 3. If the noise is caused by a broken clock spring or a loose clock spring connector, replacing the clock spring or securing the connector will fix the issue. 4. If the driver hears a clunking sound when turning the steering wheel while stationary or at low speeds, or feels vibration or knocking in the steering wheel, or if tire noise increases while driving, it may indicate a faulty thrust bearing. The thrust bearing connects the car body and the shock absorber to prevent direct friction and consists of components such as a dust cover, raceway, and ball bearings. It is located at the top of the shock absorber assembly and typically has a lifespan of 40,000 to 60,000 kilometers. Once it reaches its service life, it is recommended that the owner have it inspected.

What's the difference between R16 and R17 tires?

R16 tires and R17 tires have the following differences: 1. R16 tires are designed to fit 16-inch rims, which are relatively smaller in size; while R17 tires are designed for 17-inch rims, making them larger compared to R16 tires. 2. Generally speaking, larger car tires have a lower aspect ratio. Tires with lower aspect ratios provide better feedback on road conditions and stronger lateral support during driving. Conversely, smaller car tires have a higher aspect ratio. Tires with higher aspect ratios offer better driving comfort, but their road feedback and lateral support are relatively weaker.

How to Lower the Vehicle Height?

Lowering the vehicle height can be achieved by installing shorter springs, or by replacing them with coilover suspensions or modifying to air suspension. Related details are as follows: 1. Lowering the vehicle height can enhance the car's appearance, improving visual appeal, and also increase stability during high-speed driving. 2. While modifying with coilover suspensions can lower the chassis, it may compromise ride comfort. Air suspension is more common in high-end models, allowing height adjustment through inflation and deflation. 3. Modifying to air suspension requires an air tank and pump, which are often placed in the trunk. The vehicle chassis is not necessarily better the lower it is; moderate modifications are acceptable, as an excessively low chassis can affect road clearance and drivability.

Can the battery be charged when the car is idling after starting?

Idling the car after starting cannot charge the battery. The standard procedures for charging the battery are as follows: 1. Voltage; The battery already has a certain voltage. When the voltage is below 13.4V, starting the car will be difficult. To charge a battery at this voltage, it generally requires the engine to run at over 1500 RPM, and sometimes even over 1700 RPM. 2. RPM; If the battery does not have enough power to start the engine, maintaining the engine at over 1500 RPM for more than 20 minutes can provide enough charge for one start. Maintaining it at over 1500 RPM for more than 30 minutes can provide enough charge for a start the next day. 3. Time; If you need to charge the battery more fully, based on the second point, it is best to charge at over 1900 RPM, and the time can be adjusted as needed.
