What does 19560r16 tire mean?
1 Answers
In the 195-60r16 tire, 195 indicates the tire width is 195mm, 60 represents the aspect ratio (the percentage of the tire's section height to its width) at 60%, r stands for RADIAL, meaning it's a radial tire, and 16 denotes the rim diameter of 16 inches. Wheel size refers to the diameter of the rim, and one should not blindly pursue larger sizes. Larger diameter rims, which offer better handling performance, are suitable for sports cars and racing vehicles, hence they can also be chosen for sporty cars. Smaller rims may look less impressive but can make the car more comfortable and fuel-efficient. Load index refers to the maximum weight a tire can bear under standard tire pressure, so the vehicle's load must not exceed the corresponding load mass indicated by the index; otherwise, it may affect the safe operation of the vehicle. Speed rating refers to the certified speed grade of the tire, ranging from 4.8 km/h to 300 km/h. The speed rating letters include J, K, L, M, N, P, Q, R, S, T, U, H, V, W, Y, and ZR, where J-Y represent speeds of 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 240, 270, and 300 kilometers per hour, respectively. Besides the model, tires also display the following common data: Tire cord material: Indicated 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 a specified load under defined conditions. Letters A to Z represent the tire's certified speed grades from 4.8 km/h to 300 km/h. Commonly used speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Shows the rim size compatible with the tire for practical use, e.g., standard rim 5.00F. In daily use, the following points should be noted for tires: Regularly inspect the tire surface for defects such as cracks or deformations. Due to wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it loses its drainage and anti-slip functions, significantly reducing the car's performance. Even small cracks can be a hidden danger for tire blowouts at high speeds. Additionally, promptly remove pebbles from the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials that deteriorate rubber. After parking, the driver should not turn the steering wheel, as this action accelerates tire wear. Do not splash water for cooling. In hot weather or during high-speed driving, tires are prone to overheating, and the pressure increases. In such cases, stop to allow the tires to cool down naturally. Never release air to reduce pressure or splash water to cool, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent use of brakes and sudden stops to prevent accelerated tread wear caused by dragging between the tire and the ground.
