Math...check...exactly. <img src="/forums/images/graemlins/smile.gif" alt="" />

30 x PI (3.1416) = 94.248 (circumference in inches)



K? <img src="/forums/images/graemlins/wink.gif" alt="" />


And your tire is 'not' 30 in....Take a tape and measure from the ground to the center of the axle ..Then times (X) that number by two ..That will get you the 'real' tire size the 'rolling tire size'..No matter what the tire says on it they are always wrong on the real size


Absolutely sorta correct! Tire does grow at speed. a little.

But to be at 3500 RPM at 55 MPH his tire "real" height would be 21"
