[QUOTE="69ST, post: 97609, member: 5"] Tire circumference can have a significant affect on overall gearing, i.e. revs per mile. Since you're attempting to change effective gearing, now is the time to realize that there are some big differences between nominal (sidewall markings) sizes and actual sizes. Six different tires of the same nominal size can be six different actual sizes...varying from one manufacturer to another, even between different tires series (models) from the same manufacturer. Thus, there may be some trial & error in your future as you attempt to source the best real-world size. If you're looking to go with a shorter tire (smaller circumference) your choices are: 3.50-10, 90/90 - 10, and 100/80 - 10 4.00x10 tire circumferences can range from a little more than 57" down to about 55". (Knobbies, such as Trailwings, tend to run larger than street tread tires) I've seen 3.50 x 10s as small as 52". My firsthand experience in actual tire sizes is limited, there is almost certainly a lot more variation, especially in-between the measured extremes I've encountered, so far. That still gives you roughly 8-10% to work with, possibly exceeding the minimum needed to correct your gearing issue. [/QUOTE]
