Currently running true 35” tires

if the truck allows with no lift or level. If not im sticking with the current tire. So from the research i have found this calculator that seems very accurate at telling you your RPM’s with the entered information, ring gear ratio, tire hight, MPH, transmission final gear ratio.
So you can enter any variation you want including the final drive gear ration for 3rd, 4th, 5th, 6th....ect.

So. If you had my setup of 35” or 35.7” tires would you go with 4.56’s or 4.88’s?
Here is the final drive ratios for my 66RFE
1st. 3.23
2nd. 1.84
3rd. 1.41
4th. 1.00
5th. .816
6th. .625
Thank you for the opinions and help
