The 325/60R18 tire has an overall diameter of approximately 33 inches, a section width of roughly 12.8 inches, and is designed to be mounted on an 18-inch diameter rim. The equivalent tire size in the high flotation system is 33×12.8R18.
What does 325/60r18 Tire mean?
Let’s begin by unraveling the enigma of the numbers and letters on your tire. Here’s a quick cheat-sheet to get you started:
| Tire Number | Its Explanation |
| 325 | The “325” in the tire size is the tire’s section width in millimeters. It measures the widest part of the tire, from sidewall to sidewall. |
| 60 | The “60” is the aspect ratio of the tire. It represents the height of the tire sidewall as a percentage of the tire’s width. In this case, the tire’s height is 60% of 325mm. |
| R | The “R” stands for radial construction. Most modern tires are radial tires, which means the internal ply cords are arranged radially, or 90 degrees to the direction of travel. |
| 18 | Finally, the “18” indicates the diameter in inches of the wheel or rim that the tire is designed to fit. |
What is 325/60r18 Tire in inches?
You might be more familiar with measurements in inches rather than millimeters, so let’s convert the 325/60r18 tire size into inches. Hold on to your lug nuts, because here we go:
325/60r18 in Inches and Millimeters
| Measurement | Inches | Millimeters |
| Tire Diameter | 33.40 | 848 |
| Section Width | 12.80 | 325 |
| Rim Diameter | 18 | 457.2 |
| Sidewall Height | 7.68 | 195 |
| Circumference | 104.93 | 2665.13 |
| Revolutions | ~604 rev/mile | ~375 rev/km |
The tire diameter is derived from adding the height of two sidewalls to the rim diameter (7.68″ + 7.68″ + 18″ = 33.40″). Section width remains the same as it was already provided in the original tire size.
The rim diameter is straightforward as it is the ’18’ part of the tire code. Sidewall height is calculated by multiplying the section width by the aspect ratio, then dividing by 25.4 (to convert from millimeters to inches).
Tire circumference is derived from multiplying the tire diameter by pi (π) and the revolutions per mile are determined by dividing 63360 (the number of inches in a mile) by the tire’s circumference.
