Understanding Tire Size Designations

Okay, so you've probably seen those cryptic numbers and letters on your tires and wondered what they all mean. No worries, I'll break it down for you! Tire size designations might seem like a jumble of numbers and letters, but each component provides crucial information about the tire's dimensions and characteristics. Let's break down a typical tire size designation to understand its meaning fully. For example, consider the tire size 205/55R16. The first number, '205,' indicates the tire's width in millimeters. This measurement represents the distance from one sidewall to the other when the tire is properly inflated and mounted on a wheel. The larger the number, the wider the tire. Next, '55' represents the aspect ratio. This is the ratio of the tire's sidewall height to its width, expressed as a percentage. In this case, the sidewall height is 55% of the tire's width. A lower aspect ratio means a shorter sidewall, which can improve handling and cornering stability. The letter 'R' signifies that the tire is a radial tire.
