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 NumberIts Explanation
245The first three digits (245) indicate the section width of the tire, or how wide the tire is in millimeters (mm) from sidewall to sidewall.
75The 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.
RThe ‘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.
17The 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.

Tire DiameterApproximately 30.47Approximately 774
Section WidthApproximately 9.65245
Rim Diameter17Approximately 432
Sidewall HeightApproximately 7.23Approximately 183.75
CircumferenceApproximately 95.72Approximately 2431.52
Revolutions per MileApproximately 662N/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!
