3 Finding the Circumference of a Tire

4 LT 265/75R16 Example

5  Step 3  mm/25.4mm = 7.82 inches  Step 4  D=2H+R  D=2(7.82)+16  D=31.64 inches

6  Step 5  C=D  C=3.14 (31.64)  C=

7 Effect of changing factory – installed Tires  The following principles apply when determining actual distance and speed traveled according to tire size:  Actual mileage = k odometer reading (mileage)  Actual speed = k speedometer reading (miles per hour)  where k =  circumference of bigger tire  circumference of factory-installed tire  Since the value of k = for the two tires in comparison, (20,000) = 22,256  miles (actual) and (60) = miles per hour (actual).
