## What is Tractor Tyre Rolling Circumference?

The rolling circumference of a tractor tyre is the distance it travels in one complete revolution. It’s important to know this measurement because it affects the accuracy of your tractor’s speedometer and the accuracy of the work being done by any implement attached to the tractor.

## Tractor Tyre Rolling Circumference Calculation Formula

To calculate the rolling circumference of a tyre, you can use this formula:

**Rolling Circumference (in inches)** = (Tyre Diameter in inches x 3.14) + (2 x Flat Section Width in inches)

Keep in mind that this formula is just an approximation and actual rolling circumference may vary slightly due to factors such as tyre wear and inflation pressure.
