Here are the methods to check: 1. Tread Width: The width of the tire is one of the factors that affect the vehicle's fuel consumption performance. The wider the tread, the larger the contact area with the ground, and the greater the friction between the tire and the ground. When traveling the same distance, wider tires tend to consume more fuel. However, wider tires also provide stronger grip, better handling, and better resistance to lateral forces. Conversely, narrower tires have lower fuel consumption and a lighter driving feel, but due to the smaller contact area with the ground, the grip is not as strong. 2. Aspect Ratio: The aspect ratio refers to the ratio of the height from the rim to the tread to the maximum width of the tire's cross-section. Simply put, it is the height-to-width ratio of the tire. Most cars on the market today use tires with small widths, small inner diameters, and large aspect ratios. Tires with high aspect ratios have longer sidewalls, which generally provide higher comfort. 3. Rim Size: The rim, commonly known as the wheel, forms the wheel together with the spokes. Rims and spokes can be divided into three types: integral, permanently connected, or detachable. The nominal width and nominal diameter of the rim are expressed in inches. 4. Load Index: The load index refers to the maximum load that the tire can bear, represented by a code. The larger the value, the greater the load the tire can bear. You can check the corresponding load index and value. For example, if a Goodyear tire has a load index of 95, its maximum load capacity is 690 kilograms.
