My Procal just arrived today, now that my speedometer is making sense again I'll be interested to see what I'm getting for mileage.
I'm getting about 17 mpg with my rig running 35's. TF 2.5 and BFG All Terrains. Equipment details in the signature below. With OEM stock Sport tires I got about 2 mpg better.

If I had it to do over again I wouldn't do anything different. 35's belong on a JK, IMHO.

17 on the 35's with the speedo corrected for the tires I assume?

I can guarantee you my truck was not touching 17 on the 35's on the stock gears, but I never corrected the speedo at that time, so I have no way of knowing the true economy.

You're a two door, that buys you some mileage because you're lighter...

Now that the 4.88's are in and the speedo is adjusted, we'll see. 17 would be nice.
 
Thanks for the reply. I might go with 4.56
Important to note (I forgot to mention) that the 3.6pentastar Wranglers don't need as much gear change. I was reading today that. 4.10 is the sweet spot for 35s on those engines. Do the homework before you install.
 
Trust me when I tell you this: GET THE 35'S. If you don't you will wish you did. 35's look just right on a JKU.

Kelly Safari TSR 315/75/16. Most 315's don't work out to be 35 when mounted and installed on the Jeep. Mine were 34.8 inches off of the Jeep. 33.8 when mounted and put on. I have a 19/60 spring swap and Daystar 1.75 inch Comfort Ride lift. No rubbing.

 
2.5" TeraFlex spring lift with 35x12.50x17 Pitbull Rockers on Level 8 Trackers.
Kick ass :thumb:

I had to be different and went with 35" Handkook MT's on the newer Level 8 ZX. There's a optional rock ring that can be purchased to protect the wheel.

2.5 Rk coils but with only a front bumper. Actual height is 3.5" +

i had 4.88 gears installed 2 months ago and i couldn't be happier. 70 mph is 2700 rpms in sixth gear. 4.88 feels right and i am not regretting it at all. getting 15 and 16 mpg

It varies by driver.. The person I was talking to didn't want RPM over 2500 at highway speed... So actually you calling the Pentastar at 2700 with 4.88 is probably pretty helpful for him.

Thanks for making the numbers work.
