What does 175/70r14 mean?
2 Answers
The following is the explanation of 175/70r14: 1. 175 indicates the tire width: the tire width is 175 millimeters. 2. 70: called the aspect ratio of the tire. 3. R: is the international code for radial tires. 4. 14: refers to the diameter of the wheel hub is 14 inches. Here is the extended information: 1. Radial tires are a type of tire structure, different from bias tires, arch tires, and pressure-regulating tires. The international code for radial tires is "R", commonly known as "steel wire tires". 2. The aspect ratio of a tire. The ratio of the height to the width of the tire's cross-section. The aspect ratio on the tire specification is displayed as a percentage, with the percent sign generally omitted, usually including types such as 80, 75, 70, 65, 60, 55, etc.
I've been driving for over 20 years as an experienced driver, so I can easily understand tire codes like 175/70R14. The 175 refers to the tire width of 175 millimeters, about the width of a palm, which affects the car's grip. The 70 is the aspect ratio percentage, meaning the sidewall height is 70% of the width—the higher this number, the softer the ride. R stands for radial construction, which most cars use nowadays. The 14 is the rim size in inches, telling you what size wheel it fits. When choosing tires, the width affects fuel consumption and stability; a higher aspect ratio provides comfort but can make the car feel unstable in corners, while a lower one improves handling but makes bumps more noticeable. When I change tires, I always prioritize the original specifications—safety comes first. Don’t randomly alter sizes, or you could end up in trouble if an accident occurs.
