2nd Gen Non-Engine/Transmission Bug Out> Did you ever get an answer

[jponder]

I was wondering about gear ratio's and was looking at Fritz web site, tire sizes etc, auto's with 3. 54/4. 10 etc.





A CTD with a auto and 3. 54 gears at 59 MPH is at 1600 RPM.



A CTD with 4. 10 gears at 1600 RPms is at 51 MPH, a 8 MPH loss.



Now, figuring that a 4. 10 takes 8 MPH from a CTD at 59, a 3. 73 rear ratio would take 4MPH from a 3. 54?..... ?( Approx>>>not exactly)



So would the same differance be applied

by changing tire sizes( from the chart on Fritz)

from a 265/75/16 to a 225/75/16 would lose approx 4 MPH???



The MPH Vs. RPM change the same, but one is only changing tire dia?



I want to make sure this would be in essence, the same as a gear change but not, and only a tire dia change.



Is this right or ?????



Thanks in advance.
