I'm not sure how accurate you're trying to get. If you use the approach below it will take into account all the variations that have been discussed. The key is driving 60 miles an hour only.
Time a 10 mile drive on the highway using the mile markers as your measure doing 60 MPH consistenty.
Then use the following calculation for the "# Teeth Needed"
# Teeth # Teeth
on Gear Now Needed # teeth on gear now X 600 (seconds)
----------------------- = ---------------------- or # teeth needed = -----------------------------------------------------
Time in seconds 600 seconds time in seconds for 10 miles at 60 MPH
for 10 miles at
60 MPH
Use the listing below to determine which color gear you need.
