3:55 or 3:91?

Your tires are 25.1 inches tall and turn 803 revolutions per mile. 803 x 3.91
equal 3139 rpm at 60. Kinda high. 803 x 3.55 = 2850 at 60mph. Liveable.
803 x 3.23 = 2593rpm at 60. This is assuming you don't have an OD trans.
FYI: 3.91 at 70 would be 3662. I guess it depends how tight you want to
twist it.
