How to generate random car tire size?
Introduction
Car tires are identified using a standardized code that conveys key technical specifications. An example of such a code is 195/65R15. Each component of this marking provides essential information about the tire’s dimensions and construction type, which are critical for compatibility, performance, and safety.
The first number, 195, refers to the tire’s width in millimeters, measured from sidewall to sidewall. Following this is the forward slash (/) and a two-digit number indicating the tire profile, also known as the aspect ratio. In this example, 65 means that the sidewall height is 65% of the tire's width. That results in a sidewall height of 126.75 mm (65% of 195 mm).
The letter that follows the aspect ratio indicates the tire’s construction type. In this case, the letter R stands for radial construction, which is the most common type used in modern passenger vehicles. Radial tires have layers arranged perpendicularly to the direction of travel, offering better grip, fuel efficiency, and tread life compared to older bias-ply designs.
The final number, 15, specifies the diameter of the wheel rim that the tire is designed to fit, expressed in inches. So a 195/65R15 tire is made to mount on a 15-inch rim. Understanding this code ensures proper tire selection and helps maintain optimal vehicle performance and safety.
