If 75 is the circumfrance in inches, then the height or dia of the tire would be 23.8732414637843" tall.

The 75 is not the circumference, but the sidewall height multiplier or profile. 225 centimeters divided by 25.4 = 8.86 inches. 8.86 X .75 = 6.65" sidewall height. 6.65 X 2 = 13.3". 13.3 + 14(rim size)=27.3 " total height.
