When you take a quick look at a tire sidewall, the sequence of numbers and letters might seem mysterious, but they actually communicate crucial details about the tire's specifications. Let's break down the sample tire size LT325/65R18/D T to uncover its significance.

This stands for Light Truck, indicating that the tire is designed for use on light trucks rather than passenger vehicles.
Width: 325
The first number, 325, denotes the width of the tire in millimeters. In this case, the tire's width spans 325 millimeters from one sidewall to the other.
Profile: 65
Following the width is the aspect ratio, represented by the number 65. This figure indicates the height of the tire's sidewall as a percentage of its width. In our example, the sidewall height is 65% of the tire's width.
Rim Size: 18
The next number, 18, specifies the diameter of the wheel rim in inches that the tire is designed to fit. Therefore, this tire is intended for a 18-inch diameter rim.
