The logic: First, compute the circumference of the tire. This is the actual distance each tire must travel as a dual.
TIRE A: 480 rotations @ 10.996 ft. per rotation – 5280.0 FEET TIRE B: 480 rotations @ 11.028 ft. per rotation – 5295.7 FEET
Subtract the difference to see how many skid feet per mile is wasted. Measuring how mismatched diameters affect performance.
SKID FEET PER MILE – 15.7 FEET
