Rocky road lift kit, 285/75/17 terra grapplers
 
So after getting my lift on i then purchased 1.5" wheel spacers from ezaccessory.com and got the nitto terra grapplers at in 285/75/17 33.8"..if you use 1.25" spacers it is the best so you dont hit the front bumper when turning and there is a ridge of metal on the backside of the front wheel wells that has to be hammered flat or you will not be able to get full turn with compressing, take out the front liners and hit the ridge towards the center of the vehicle to fold it over and get more room, with doing that i now have no rubbage and will throw pictures up once i figure out how, i also have the rocky road roof rack, with these addons the mpg went from 18-14 mpg, pretty bad change, and the speedometer is off about 9 mph at 60, my radar dtector tells me im doing 69-70 mph.

Are you calculating mileage or using the EVIC? It isn't accurate ate the best ot times. Lets see some pics.

If he's using EVIC both before and after, it will be much more accurate than by hand. His odometer is also off now (as is his speed). I never calculate mpg manually. I reset EVIC at every fill, and drive.

This is why I'll never raise or oversize my tires. I bought the V6 for MPG. It takes a heavy foot to get it moving on stock tires.

Are you serious? It's easy to figure out the percentage difference between OEM tire size and what he's running. There's enough odometer checks on highways to check it or go to the rimsntires website and they have a calculator. I run P275/55/20 Silent Armor, they're 4% larger. Add that to your mileage before dividing your fuel. Not trying to offend but using the EVIC is not the most accurate way of figuring out fuel consumption. When driving a Jeep fuel economy should be the last concern anyway. Our Hemi Overland isn't great and my JK on 37s is worse, it wasn't a concern when we bought them. Glad you're happy with the OEM tires I like bigger tires for looks and performance. Sorry to high jack your thread. Post pics.

Yea im sure its not accurate at all but i do notice that for 100% i have to fill up a lot more and the gas dte never gets above 350 with fill up and that sucks, but oh well

I was wondering why this got moved out of the WK2 section, I've never looked at this sub section before?
