What is the size of an R14 tire?
2 Answers
175/65R14 and 165/60R14 tires both have a diameter of 14 inches. Here is the relevant information: The meaning of 175/65R14: 1. "175" refers to the section width of the tire, which is the width between the two sidewalls (in millimeters). This width varies depending on the width of the rim the tire is matched with—wider rims are paired with wider tires, and narrower rims with narrower tires. Generally, the width marked on the sidewall indicates the width when the tire is mounted on the recommended rim width. 2. "65" is the aspect ratio of the tire, representing the ratio of the tire's height to its width. Here, it means the height is 65% of the width. The smaller the number, the flatter the tire appears. 3. "R" indicates the tire's construction, meaning it is a radial tire, with its cord plies arranged radially within the tire body. 4. "14" denotes the rim diameter (in inches). This tire must be matched with a 14-inch rim; otherwise, it cannot be installed.
As an experienced driver who has driven various car models, I find many people have questions about tire sizes. For example, an R14 tire actually means a 14-inch rim diameter. On the sidewall markings of a tire, such as the code 195/65 R14, the 'R' refers to the radial tire construction, and '14' indicates the rim size in inches. This means when replacing tires, the rim must be 14 inches to ensure compatibility. Using an incorrect size can affect vehicle handling and fuel efficiency, and may even pose safety risks. I recommend car owners regularly check tire wear and ensure accurate sizing to avoid issues during long trips. You can easily confirm the size by checking the sidewall markings yourself. Remember, R14 tires are designed for 14-inch wheels.
