Dude, you win for having the most threads posted in the G1 section.
It's the tire size chart which goes like this:
195 is the tire width in millimeters from sidewall to sidewall.
60 means that the sidewall height is 60% of the 195mm width and the 14 is the 14" rim size they fit on. So if I'm not too tired and doing this right, your 195 tire will have a sidewall height of 117mm and the 185 will have a sidewall height of about 120.25mm. The 195 would then be a lower profile tire and a bit wider than the 185.
