I know this might be opposite of what most of us jeep people do, but I am on my 3rd Jeep at this point. I have had all wranglers, a 95, then a 97, and now a 2002. My first two, I went bigger and bigger with every modification imaginable until I either ran out of money or couldn't afford to drive it anymore or both. With my 02, I have resisted the urge thus far to go bigger than stock, and have been running 31X10.50 BFG AT for a while now. I average around 18 MPG. Is there any way to increase this? With where gas is heading, I would like to do everything possible to better my position. My jeep is a daily driver, and I commute about 30 miles one way. I know 18 mpg isn't that bad, but every bit helps. If I were to go down a size in tire to a 30X9.50 would that help some? Where I go off road it is mostly for hunting and camping, so ground clearance isn't that important...Any other suggestions, even aftermarket stuff that might help in the MPG department. By the way, my TJ has the 4 banger. Thanks in advance for any help!
