Conveniently, it is twice as long as the radius of a circle. 0000004302 00000 n The formula v = ωr can be rearranged to solve for the angular speed ω: This is also the angular speed at the outer edge of the wheel, where the radius is r = 0.220 m. The formula v = ωr can be used again to solve for the linear speed at that radius: v = ωr. Divide by 12 to get 7.854 feet. The RPM (revolutions per minute) is of the wheel, not the engine. Enter any single value and the other three will be calculated.For example: enter the diameter and press 'Calculate'. ! H�\��j�0F�~ The Tire Diameter Calculator will instantly calculate the diameter of a tire if you enter in the tire width (in millimeters), the tire aspect ratio (also known as the tire series), and the wheel size (in inches). Radius of a wheel is the span between center and edge, diameter ist twice the radius, the span from edge to opposite edge.

The wheel diameter d w [mm] is the sum between the rim diameter and twice the height of the tire: \[d_{w} = D + 2 \cdot H \tag{3}\] The (free static) wheel radius r w [mm] is half the wheel diameter: \[r_{w} = \frac{d_{w}}{2} \tag{4}\] To take into account the deformation of the tire, we can apply a coefficient of 0.95, which means that the free static radius will decrease with approx. Wheel circumference in feet = diameter times pi = 27inches/12 inches per foot times 3.1416 = 7.068 feet wheel circumference.
