Are those rims chrome or polished? Jeep looks awesome.

I understand the extra weight and the aerodynamics diminish gas mileage, but I just dont want to make the same mistake I did on my last 4x4. I had a 06 nissan titan crew cab - 6" inch lift with 35's; I only got 8 miles per gallon.
Point being; I plan to regear for either 35's or 37's, stuck between the two sizes and I was wondering what some of you are getting highway and city. I drive hard so please give me numbers if you drive similar or if you have a valuable input.
Ill be driving 60% highway, 20% city, and 20% off road, any advice whether 35's or 37's would be beneficial. I am planning on getting t-flex 4"; 1" more body lift and 4.88 or 5.13 gears; 13.5 wide tires on 35's or 37's.

Thanks for the advice
Brian, az

I reread my thread and it sounds like I am expecting miracles at the gas pump, rather, I just want to get atleast 10- 12 in the city and 12- 15 on the highway. Is this possible with regearing and 35's/37's ?

I get 12-15 on the highway with 4.10s and Auto with my 35s now before regearing, not that I'm proud of it!

It sounds like 4" Tera plus 1" body lift would be overkill if you go the 35 route though

Kidjeep:
Thanks for the information; I was planning on the the 4" for the 35's and the 4" +1" BL with 37's.
From what I researched at local shops and reading a lil' bit on this forum, I have heard MPG improvements upwards of 2-4 mpg. I talked to three local shops and they all suggested 4.56's with 35's (thats considering my 60% highway, 25% city, 15% offroad - in other words - daily driver) He said the 4.88's and 5.13's on 35's improve off-the-line power, but the rpms run a little higher than stock.

If you are getting an automatic and want to run 35's or bigger, trust me, get the 5.13 gears. If you are getting a stick and 35's, I'd say 4.88's. Stick and 37's get 5.13's. You can thank me later. If you get 4.56's (when they become available) you will be disappointed you didn't get the other gears.

Thanks Redrock,
Im going auto, and plan to run 4.56 - 4.88's for 35's and 4.88 or 5.13 for 37's. do you run 37's, and if so are the 5.13's the best for good highways speeds? How about gas mileage?

I have 4" lift, 37s, and an auto with the 4.10 gears (2007 X w/ tow package). I have not regeared yet, but plan to in the future. Also, I live in Florida, so its not hilly, which I think is the only reason I haven't had to regear. I do drive with the overdrive off, though.

I think I get about 14 mpg around town. I figured this by the fuel light coming on at ~220 miles. Add 20% to that to compensate for the 20% larger tires, and my real miles to the tank is 264. divided by 18 gallons is 14.6 mpg, then round down to be a little more realistic.

Also, the dash info tells me that I'm getting ~12, so add 20% to that and I get the same result.



Here's some pics for the heck of it:

Looks great guys. I really want some 37"s

thanks for the numbers, it helps. Have you got a body lift or is it just the 4" (what brand). Any tranny problems? i hear the 37's can cause tranny problems.
