The 305/65R17 tire has an overall diameter of approximately 32.6 inches, a section width of roughly 12 inches, and is designed to be mounted on a 17-inch diameter rim. The equivalent tire size in the high flotation system is 32.6x12R17.
What does 305/65r17 Tire Mean?
To help you understand, we’re going to break down the 305/65r17 tire size using a simple table.
| Tire Number | Its Explanation |
| 305 | This is the tire’s width in millimeters. It signifies the widest point from sidewall to sidewall. |
| 65 | This is the aspect ratio of the tire. It represents the height of the tire’s cross-section as a percentage of its width. So in this case, the height is 65% of 305 mm. |
| R | This letter stands for Radial, which refers to the construction of the tire. Radial tires have layers of fabric that run radially across the tire. |
| 17 | This represents the diameter of the wheel rim in inches. In this case, the tire would fit a 17-inch wheel rim. |
What is 305/65r17 Tire in Inches?
We’ll make the metric to imperial conversion for those of us who are more comfortable with inches. This also helps when you’re trying to compare tire sizes that are in different formats.
Now let’s dive into the table.
| Measurement | Inches | Millimeters |
| Tire Diameter | 32.6 | 829 |
| Section Width | 12.0 | 305 |
| Rim Height | 17.0 | 431.8 |
| Sidewall Height | 7.8 | 198.2 |
| Circumference | 102.4 | 2601 |
| Revolutions | 619 per mile | 384 per kilometer |
Here’s how we came up with those measurements:
- Tire Diameter is calculated as [(305 * 0.65 * 2) / 25.4] + 17 = 32.6 inches.
- Section Width is just the direct conversion of 305mm to inches, which is about 12.0 inches.
- Rim Height is the diameter of the wheel rim, already given as 17 inches.
- Sidewall Height is calculated as (305 * 0.65) / 25.4 = 7.8 inches.
- Circumference is calculated as diameter times pi (π), which is 32.6 * 3.14 = 102.4 inches.
- Revolutions per mile is calculated as 63360 (inches in a mile) divided by the tire’s circumference, roughly 619 revolutions per mile.
With this information at your fingertips, you’re now an unofficial tire size guru! Don’t go throwing around your tire size trivia too casually though – with great power comes great responsibility.
