Tire aspect ratio is calculated by tire width in mm + aspect ratio percentage of tire cross-section + tire type code + rim diameter in inches + load index + speed rating code. Below is a partial introduction about tire aspect ratio: 1. Function: It is a major factor affecting a vehicle's sensitivity to road conditions. Vehicles with lower aspect ratios have thinner sidewalls and tires that bear greater pressure, making them highly sensitive to road conditions. This allows rapid transmission of road signals to the driver, facilitating better control, commonly seen in performance-oriented models. 2. Feature: Higher aspect ratios result in thicker sidewalls, providing ample cushioning but poorer road feedback, especially feeling more sluggish during turns, commonly found in comfort-oriented models.

What is the minimum ground clearance of the Beijing Hyundai Fista?

The official minimum ground clearance data for the Hyundai Fista has not been released. According to relevant reports, the minimum ground clearance of the Fista is approximately 150mm. Related information about minimum ground clearance is as follows: Introduction: Minimum ground clearance refers to the distance between the lowest point of the car (excluding the wheels) and the supporting plane when the vehicle is fully loaded and stationary. It is used to characterize the car's ability to pass over obstacles such as stones and tree stumps without collision. Impact on driving: The smaller the ground clearance, the worse the ability to overcome obstacles. Sedans generally travel on flat urban roads, so they have smaller ground clearance. Off-road vehicles have larger minimum ground clearance to pass over larger obstacles.

What to Do When a Car Engine Won't Start?

First, check whether components such as the distributor, spark plugs, and high-voltage wires have become damp due to the car being exposed to rain. If they have, you can dry the damp components before attempting to start the engine again. Alternatively, use a hair dryer to directly dry the affected parts. Next, inspect the spark plugs to see if they are damaged. If they are, simply replace them with new ones. Generally, car spark plugs have a service life of approximately 20,000 to 30,000 kilometers. Check whether the battery voltage is sufficient. Many batteries are equipped with an inspection window for monitoring purposes. When the window displays green, the battery is functioning normally. If it shows black, the battery needs recharging or maintenance. A white display indicates that the battery should be replaced.

What tire model is used for the Toyota Vios?

Toyota Vios tire specifications are divided into the low-end 175/65R14 and the mid-to-high-end 180/60R15. These specifications are relatively common in the same class but do not offer much competitive advantage. Prices vary depending on the specifications. Relevant information about tires is as follows: When purchasing tires, always check the production date: if the production date is too old, do not buy them. Tires are rubber products and will age even if unused. During regular use, frequently check tire pressure and the surface for any damage: the tire sidewalls are relatively fragile, and if they are scratched or punctured, they cannot be repaired. It is recommended that owners replace their tires every four years, even if the mileage driven within those four years is minimal.

Why Does a Car Stall

There are many reasons that can cause a car to stall. 1. Automatic transmission models are less likely to stall, while manual transmission models may stall frequently due to insufficient driving skills. However, it is not impossible for automatic transmission cars to stall, mainly due to the use of low-quality fuel. 2. For new cars (automatic transmission), stalling is primarily caused by a lack of driving proficiency. Another possibility is issues with the car's engine or fuel system. However, for new cars, engine-related problems are less likely, and most cases are due to fuel system issues. 3. For older models, apart from insufficient driving skills, stalling can also be caused by using substandard fuel, leading to carbon buildup in the engine. Higher fuel octane ratings are generally better for the car. This thinking is correct when the fuel quality fully meets national standards, but if the fuel quality is problematic, this mindset may not hold true, as it can be harmful to the car.

Where is the Volkswagen Tire Pressure Reset Button?

Volkswagen tire pressure reset button is located in front of the gear lever, with the word SET on it. The position may vary depending on different car models. In this case, just pay attention to find the SET button. The graphic symbol is approximately a triangle with an exclamation mark inside that is not fully enclosed, which is also the display symbol for tire pressure warning. Relevant information about tire pressure is as follows: Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and the damage of the engine will lead to the exhaustion of the car's life. Then the tire pressure is the blood pressure of the car, and the level of tire pressure plays a vital role in the performance and power of the car. Hazards of excessive tire pressure: The friction and adhesion of the tire will be reduced, affecting the braking effect; causing the steering wheel to vibrate and deviate, reducing driving comfort.
