Measure the perimeter of the wheel using a tape measure. Then use the formula to find out the diameter D = perimeter/3.14 ========================================== You could certainly do it that way. But it would be much more direct to just measure all the way across the wheel, between the two points on the edge of the wheel that are furthest apart. That would be the diameter.

It depends on the wheel's diameter.
Circumference is diameter times Pi, you do the math.
Circumference is equal to the diameter multiplied by pi, or 3,14. Multiply 65 x 3.14.
The radius is half of the diameter so it is 2.5 Feet.
