I will be upgrading my 33" tires and thinking of going to 35" tires (KO2's) which will add 13lbs of dead weight to each tire. However I noticed the 37" tires are only other 3lbs of dead weight. I'll be adding a 3.5" lift. The hardest trail I run every 2 or 3 years is the Rubicon. With gas prices getting close to $4.50 a gallon MPG is becoming much more important to me. How much gas mileage do you normally lose going to a 35" tire? And your thoughts on a 35" vs 37" with gas mileage being a concern, since I don't really do that many hard core trails. Normally 95% of my driving is highway.

IMG_4963.jpgIMG_4950.jpg I’m currently running 37x12.5x17 on a 2 door sport. The picture with the fuel mpg is with the 37’s. With the 33’ factory rubicon wheels and tires I was getting anywhere from 19-23 but that’s running 60-70 mph. After doing the 2.5” lift and the 37’s I had the computer adjustable to the 37’s.

Do you have the 2.0T or 3.6 v6?
