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!

 

thanks.. anyone with pics with this setup on JKU?

 

There's an entire thread for 33s in the Show & Tell section...spend some time looking through that.
