First let me start off with saying that I have a 2008 4 door JKU Rubicon that I have had for a month now. It is my first jeep and like all new jeepers need advise on tires and lift. I have been doing research since before I got my jeep but no amount of research can match experience. After months of research I have been leaning towards the 2.5" Rough Country Budget Booster and I think 35" tires... I really want to go with 35s because I think they look really tough and look great with a 2.5" lift. My problem arises with the fact that I am driving on the highway there and back Monday through Friday and am worried about the headwind and gas mileage dropping. Please help me with telling me your experience with this setup and what you think I should do.

Thanks in advance for any help or experience. I know there are a lot of threads about 35s and I am sorry I am adding another one but I could not find one matching my issue. Thanks and please post pictures of your rigs with your reply!

 

Do it,
the four door looks great with 35s and gives you more clearance. Yes has millage will suffer, but you did not but a hybrid or electric vehicle . Enjoy

Jeeps are bricks on wheels, not designed to be very aerodynamic. Your gas mileage will suffer if you go up to 35s, don't let that come as a surprise. Best thing you can do if using it as a DD is to drive reasonable, don't floor the skinny pedal. Check out the show your 35s thread if you haven't already.

 

I too have a 08 jku auto 373 gears with 285/75/17 toyo mt 3.5 teraflex lift mileage can very a lot around town maybe 14 mpg Highway no wind 65 miles an hour could be 18mpg.

 

Get AT tires instead of MT, if you're really concerned with mileage. They won't look as "bad ass", but will have less roll resistance, netting you a bit better mileage. To get better mileage on hwy, you need to run it in the 2000+ rpm range. If you run too low rpm, you will waste gas and it will be a dog on hwy. Turn off OD, or drive in 4/5th gear (if you have stick), and be done with it. You can find tons of pics in the show and tell forum.

I dropped 2mpg in city, and maybe 1mpg on hwy after going to MT 35's. This is under good conditions. With head wind, expect to drop 2-3mpg more on hwy. It may seem like 1-2mpg isn't big deal, but it translates easily into at least $50 or more each month on gas.

 

With my 2 door Rubicon, a Teraflex 2.5 inch spring lift and 35 inch Duratracs on the highway wasn't too bad on gas. I was getting anywhere from 18-20 mpg on a 60+ mile commute. I only noticed poor milage (less than 15 mpg) when traffic was at a standstill for an prolonged period of time, or on the weekends when I was doing mostly local driving.

 

Everything is a compromise. Lift/tires lower mileage. Find a medium spot between the two extremes. With a good headwind an on the interstate, its a battle. Lets us know which route you take. Best of luck!

 

I run a 2.5 inch lift and heavy ass 35 inch toyos. It's common sense Ur mileage will suffer going higher, going with bigger and probably heavier tires. That being said I use mine as a DD and its quite the toy for my road rage lol. So lift it put 35s on and drive the shit out of it.

 

Thanks for your advise everyone I have decided to go with 35s. Any advise on which ones to go with? Mt or Lt or Ar? Brand?
