Post Tire size vs gear ratio and rpm
I am changing gear ratio in my 74 away from the 4:11 especially for the Power Tour.
This link tells you your rpms at 65 mph or 104 km/h with a 1:1 high gear transmission. http://www.intercotire.com/site63.php
for all the overdrive peeps you could use this link to figure out your rpms
