[QUOTE="Catmonkey, post: 12795177, member: 124025"] No offense taken. I'm simply passing on a common error most people make by using inflated diameters to make comparisons and calculations when changing tire sizes. Another way to determine the loaded diameter is to make a mark on upper portion of the sidewall and measure the distance between the points the marks make contact with the pavement. Divide 63,360 (inches in a mile) by that result and you have the number of revolutions per mile that mounted tire turns. It's pretty accurate when you can't find manufacturer's specs. [/QUOTE]
