# Tire Size 31×10.50r15 in Metric

Have you ever wondered what those numbers and letters on your tire actually mean? Today, we embark on a journey to demystify the 31×10.50R15 tire size and delve into its fascinating dimensions. Join us as we break down the components of this tire size and uncover the practical applications of the 31×10.50R15 size.

Dimension Breakdown
Let’s start by deciphering the puzzle of the 31×10.50R15 tire size. Each part of this size holds vital information. The number 31 represents the tire’s overall diameter in inches, while the 10.50 indicates the tire’s width.

The “R” signifies the tire’s radial construction, which is the most common type today. Lastly, the number 15 corresponds to the diameter of the wheel in inches.

## 31×10.50r15 in inches

SpecificationInches
Tire Diameter31.0″
Tire Section Width10.5″
Rim Width Range15″ x 7-9″
Sidewall Height8.0″
Circumference97.3″
Revs/Mile651

Conversion Process
Converting these measurements from inches to millimeters, the international standard, involves basic math. To convert inches to millimeters, we multiply the value by 25.4.

The overall diameter of ’31’ inches becomes 787.4 mm. The tire width ‘10.50’ inches transforms to 266.7 mm. The wheel diameter ’15’ inches equates to 381 mm.

Sidewall height and aspect ratio are two additional tire dimensions not directly mentioned in the 31×10.50r15 size. Sidewall height is the distance from the wheel rim to the top of the tire, and the aspect ratio is the sidewall height as a percentage of the tire width.

For our 31×10.50r15 tire, the sidewall height is half the difference between the overall diameter and wheel diameter. The aspect ratio is the sidewall height divided by the tire width multiplied by 100.

Finding a Close Metric Equivalent
To find a close metric equivalent, we need to translate these dimensions into a format used globally. Metric tire sizes are denoted as ‘Width/Aspect Ratio R Wheel Diameter .’ Take, for instance, a flotation tire with dimensions 31×10.50R15. This particular tire corresponds to a metric tire size of 265/75R15.
