33' Tires Gear Speedo Help.
 
I have a 1997 TJ Sport auto 33' tires and I'm doing a lot of highway travel. Im looking to increase my fuel efficiency. From what im told 4.10 gears is the way to go. What is the best combination for fuel efficiency between gears and a new speedo gear? :

For 33" tires and your 3-speed automatic, 4.10/4.11 (the front and rear axle ratios are off by .01) would be the ideal choice. A 36 tooth speedometer gear is what you'll need with 4.10 gearing and 33" tires. :)
