A sample of the default values of the MokeWerx Calculator primed for the 13" wheeled Moke, however the calculator allows you modify the input values and produce figures for any combination of rims, tyres and diffs you might be considering. Download the MokeWerx Calculator

Invent your own Moke Diff Ratio.
I was answering someone questions about how a particular Moke might perform going from one tyre specification to another but we weren't 100% sure what diff ratio was in the Moke, so I invented one, it was 4.02:1 :) Really the persons question didn't need a specific diff ratio they just need to get some ball park idea of the differences.
Using the calculator I started with RPM figures when the Moke is doing 100km provided by the owner and by changing the diff ratio figure until I got the kph figure to match 100 and that was a ratio of 4.02. Now I know a 4.02 doesn't exist but it then gave me a benchmark ratio to use in each of the tyre comparisons and we could see the changes in road speed and RPM the different specifications were going to make relative to this particular car.
