when you put 35s on and 37s i get 21 -22 highway now just want to see how much it will drop

 

I have a stock rubi on stock tires and only get 13mpg, i dont know what u guys are doing

 

Iam getting 17-19 on 37 with a Rubicon

 

I'd take it back and tell them something's wrong.....

 

thats not bad at all so you only lost like 2-3 mpg

 

I have a stock Rubi unlimited and I only get about 15 around town and 18-19 on the freeway. Except for those times when I pull up next to a Ducati at a stoplight and have to teach the rider a lesson about speed, I think I'm pretty easy on the skinny pedal.

 

I get 12-13 mixed on 35s... If you have a 6 speed it is way better I think.

 

i have 35" and 513 gear auto and get about 12mpg

 

are you guys telling your highway mpg

 

I just got back from a 7hr trip and I was getting like 15.7 when I was driving 80-85 mph. Then for the last couple hours I was driving 65-70 and ended up averaging 17 something.

I have an 08 2dr X 6-speed w/ with the 32" rubi tires, 1 3/4" front spacers, and 1" rear spacers.

....There is no reason you should be getting 13 anywhere! I was going about 85-90 for a little while, shifting between 4th, 5th, and 6th in some mountainous terrain and was at like 15, but again, I have a manual. (best decision ever! )
