The "final drive ratio" thing means a taller tire reduces the gear ratio? If I am running a 235/75/15 that makes my 2.94 an even more of a hwy gear? These are questions....Help me fishy68.
It doesn't actually "reduce the gear ratio" because that is a set figure due to the gears. But it basically does the same thing so yes your tall 235/75/15 tires make a 2.94 gear seem really tall. For instance a car with 2.76 gears and 225/60/15 tires will seem a lot lower geared than yours even though it isn't.
