1 Answers
The 195 in the tire model 195/55r15 represents the tire width of 195mm, 55 indicates the aspect ratio is 55%, r means the tire type is radial, and 15 stands for the rim diameter of 15 inches, indicating that this tire model is suitable for 15-inch rims. Following these numbers, there might be a value + V, where the value represents the maximum load a single tire can bear. The higher the value, the greater the load the tire can withstand. V stands for the speed rating, indicating the maximum speed the tire is allowed to reach. Different numbers represent different speed levels, and exceeding the tire's maximum speed may lead to dangers such as a blowout. Typically, there are also four digits before these data, such as 2515, which represent the tire's manufacturing date. 2515 means the tire was manufactured in the 25th week of 2015. Of course, there might be other letters or numbers, but they usually indicate the brand name or brand representation. Tires cannot be swapped arbitrarily. The specifications of a car's tires are determined through comprehensive analysis and testing based on the vehicle's suspension data, transmission, and engine gear ratios, among other factors. Swapping tires of different models can affect the car's stability, load capacity, power performance, steering angle, braking distance, suspension height, and more. For driving safety, it is crucial not to change tires randomly.
