What is 205 45r16?

205 45r16 is a tire size that is commonly used on sporty cars, luxury sedans, and high-performance vehicles. The first number, 205, represents the tire's width in millimeters. The second number, 45, represents the tire's aspect ratio, meaning the height of the sidewall is 45% of the tire's width. The letter R stands for radial construction, which is the most common tire construction method today. The last number, 16, indicates the diameter of the wheel in inches that the tire will fit. This tire size offers excellent handling and grip, making it popular among enthusiasts who demand performance and responsive handling. However, due to the low profile and stiff construction, they may provide a relatively harsh ride on uneven roads compared to other tire sizes.
