…all-wheel drive vehicles. Some vehicle manufacturers recommend that all tires maintain the same rolling radius and circumference, while others suggest that all tire circumferences remain within 1/4- to 1/2-inch of each other. Other vehicle manufacturers recommend that all four tires remain within…
…had a calculated diameter of 24.97", a circumference of 78.44" and rolled 835 times each mile. The same tire worn to 8/32-inch of remaining tread depth was calculated to be 1/8" shorter with a diameter of 24.84", had a circumference of 78.04" and rolled 839 times per mile.…
…similar overall diameter. While Tire Rack makes every attempt to keep the rolling circumference the same, inevitably there may be some small variation. Since the indirect systems are calibrated based on the circumference, even a small variance should be recalibrated. In the case of the more popular…
