That is the sound of friction between the pebbles and the ground. The surface of the tire has many tread patterns, and these grooves are often filled with small pebbles. Specification and Model Representation: Tires are crucial components of a vehicle, and they come in various specifications and models, each suitable for different types of vehicles. The specification and model markings are usually found on the sidewall of the tire, represented by a series of alphanumeric characters. These indicate the tire's tread width, aspect ratio, type, rim size, load index, and speed rating. Speed Rating: Based on the maximum speed they can sustain, tires are categorized into different speed ratings from A to Z, with the A grade further divided into eight sub-levels (A1-A8). The later the letter representing the speed rating, the better the tire's performance.

How many kilometers should the throttle be replaced?

The throttle does not have a fixed replacement mileage or service life. It should be replaced whenever it fails. The throttle, often referred to as the engine's throat, controls the amount of air entering the engine. Over time, carbon deposits may accumulate on the back of the throttle. Car owners can periodically clean these carbon deposits. When cleaning the throttle, it should be removed and cleaned with a professional cleaning agent. After cleaning, it should be wiped dry. After reinstalling the throttle post-cleaning, the car's computer should also be reset; otherwise, the vehicle may experience increased fuel consumption in the short term.
