The 245/75R17 tire has an overall diameter of approximately 31.5 inches, a section width of roughly 9.6 inches, and is designed to be mounted on a 17-inch diameter rim. The equivalent tire size in the high flotation system is 31.5×9.6R17.
What does 245/75r17 Tire mean?
Right, let’s decode the mystery of these alphanumeric series. It’s like your tire’s social security number, unique and descriptive. Let’s break it down!
| Tire Number | Its Explanation |
|---|---|
| 245 | The first three digits (245) indicate the section width of the tire, or how wide the tire is in millimeters (mm) from sidewall to sidewall. |
| 75 | The two-digit number (75) following the slash is the aspect ratio, a ratio of the tire’s section height to its section width. This is expressed as a percentage, so ’75’ means the height is 75% of the tire’s width. |
| R | The ‘R’ stands for Radial, which tells us the tire’s construction type. In radial tires, the internal ply cords are oriented radially, from the center outwards. |
| 17 | The last two digits (17) represent the wheel diameter. This is the size of the wheel from one end to the other and is measured in inches. |
Whew! How’s that for a tire anatomy lesson? Let’s put this newfound knowledge into practice.
What is 245/75r17 Tire in inches?
Enough with the millimeters already! Let’s convert this into inches for those of us more comfortable with the old school measurements.
Conversion from mm to inches:
1 inch = 25.4 mm. So to convert millimeters to inches, we divide the mm by 25.4.
| Measurement | Inches | Millimeters |
|---|---|---|
| Tire Diameter | Approximately 30.47 | Approximately 774 |
| Section Width | Approximately 9.65 | 245 |
| Rim Diameter | 17 | Approximately 432 |
| Sidewall Height | Approximately 7.23 | Approximately 183.75 |
| Circumference | Approximately 95.72 | Approximately 2431.52 |
| Revolutions per Mile | Approximately 662 | N/A |
To find the diameter of the tire, we calculate it as: [2 x (75/100) x (245/25.4)] + 17 = approximately 30.47 inches.
The Sidewall Height is calculated as follows: 75% of the section width (in inches) which is approximately 7.23 inches.
The circumference of the tire, important for knowing how many times your tire will rotate in a mile, is calculated by multiplying the diameter by π (Pi), getting approximately 95.72 inches.
By the way, the Revolutions per Mile is simply calculated by dividing 63,360 (number of inches in a mile) by the circumference. So for our tire here, it makes approximately 662 revolutions per mile.
Now, I hope this has enlightened you about your tire’s dimension and has made you the ‘Tire Guru’ amongst your pals!
