[QUOTE="Yardsale , post: 1017808, member: 58988"] What are you wanting to accomplish? When trying to compensate for tire diameter change, I compare the percentage change to available gear ratio changes and then include a "gut fudge factor" to compensate for weight and rolling resistance affects on acceleration. Change from 3.55 to 3.73 is 4.82%. Change from 3.55 to 4.10 is 13.41%. Sometimes jumping two gear ratios (or more) will get what is needed for the goal; sometimes fine tuning is enough. [/QUOTE]
