MPG newbie lift question
Anyone with 33s with 2.5 inch mods on JKU auto:
How much MPG do you lose on this setup compare to stock?
Do you need wheel spacers?
Any recommendation which 33 tires using stock rims?
thank you.

Lost a couple MPG at least on a JK by adding a 2.5 lift and going from stock size SRAs to stock size KMs.
The new tires have higher rolling resistance, plus I put spacers behind them.
So, the Jeep is taller, and wider below the fenders. That's a bigger brick to push through the air. Then the extra space under the Jeep leaves more room for turbulence which also drags on the Jeep. No free lunch!
