Speaking of transmissions,

If I run my transmission with a 10 tooth on the EVW and a 30 tooth on the middle 
shaft, and repeat on to the drive shaft, I have a 6:1 ration.  If I then have a 4 
inch drive wheel on a TTS, what is my final gear ration?

And if I go smaller in diameter of the drive wheel, I get more torque and less 
speed, correct?
