195 (Width): The tire is 195 millimeters wide from sidewall to sidewall. A wider tire generally provides better road grip and stability.
40 (Aspect Ratio): This means the tire’s sidewall height is 40% of its width. So, 40% of 195 mm = 78 mm sidewall height. This is considered a low-profile tire, giving a sporty look and improved handling, but less comfort on rough roads.
R (Radial): Indicates the tire is of radial construction, which is standard in modern vehicles. It offers better durability, fuel efficiency, and performance.
16 (Rim Size): The tire fits a 16-inch diameter wheel (rim). This must match your vehicle’s wheel size.
