Gearbox and Tyre Calculator

by

David Tocher

This page was based on tyre data, suitable for Pembletons, collated by Mike Meakin and a spreadsheet written by Tony Dawson. The gearboxes are all post 1970 2CV models. If people provide additional data then contact me and I'll add it to the calculator. This page requires Javascript.

A 'long' box refers to a 2CV gearbox with a Dyane CW&P and a 'short' box refers to a Dyane gearbox with a 2CV CW&P.
