Thanks for that information. That really helps with gearing ratio if i go with the 255's whichFiguring the previous owner did not upgrade the gearing; then your factory gearing is 3.07s.
The original tires were probably 215/75x15 that were 27.7", the present tires are 32.8" and the tires you are looking to go to are 30.6".
Your Jeep will feel sluggish when accelerating due to the wrong gearing for the tire size; to get the gearing to where it should be for that 32.8" tire you will need 4.11s and the 30.6" tire will require 3.73s.
would be 3.7. If i am reading you correctly.
So you think that moving from stock 215's up to 255's is enough of a leap. Way down from the
current 305's.
