What is the diameter of a 26-inch tire in centimeters?
1 Answers
The diameter of a 26-inch wheel rim is 66.04 centimeters, which is 660.4mm, because one inch equals 25.4mm. The wheel rim refers to the cylindrical metal component that supports the tire from the inside, with its center mounted on the axle, also known as the wheel ring or steel ring. It is an important part connecting the brake drum or brake disc, wheel disc, and half-shaft, working with the tire to support the wheel and also determining the tire's specifications. Depending on the characteristics and needs of different vehicle models, the surface treatment process of wheel rims can vary, mainly divided into painting and plating. For ordinary vehicle models, wheel rims are less considered in terms of appearance, with good heat dissipation being a basic requirement, and the process mostly involves painting. Plated wheel rims can be further categorized into silver plating, water plating, and pure plating. Although silver-plated and water-plated wheel rims have bright and vivid colors, they have a shorter durability period. In addition to the model, tires also bear the following common data: 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 tires. Speed rating: Indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters from A to Z represent the certified speed ratings of tires 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. Rim specifications: Indicate the rim specifications compatible with the tire for practical use, such as standard rim 5.00F. Precautions for tires: Generally, tires installed on a car can be used for four years, so it is recommended to replace them every four years. When buying new tires, always check the production date because tires have a shelf life. Typically, unused tires have a shelf life of three years. After installing new tires, it is essential to recheck the dynamic balance of each wheel to prevent abnormal vibrations during high-speed driving. If the wheels vibrate abnormally at high speeds, it can affect the vehicle's high-speed stability and handling. During regular vehicle use, frequently check the tire pressure. Pressure is crucial for tires. If the pressure is too high, the contact area between the tire and the ground decreases, reducing the tire's grip. If the pressure is too low, it can cause wave-like deformation of the tire during high-speed driving, accelerating the aging process.
