In a bind and don't have web but have a calculator.

for a 265-70R16

265 is width in mm (convert to inches by dividing 25.4) = 10.43
70 is the percentage of the width that is the side wall height (10.43 * .70) = 7.3
Diameter of the wheel + 2 sidewalls (7.3 * 2 + 16) gives the overall height. = 30.6
