Question for those that have lifted and running 37" tires. Did it change how much effort needed to turn the wheel on or off-road? Straining the electric pump? Just seems like the electric pump would be under a pretty good load with a heavy wheel/tire combo. Really looking to see how 37" tires are working for the 2.0 guys as well.

Was on 35s almost from the day I brought it home a couple months, and 37s for about 9 months now, and we wheel about every weekend absolutely no issues......:).

When aired down I can really tell the difference, but running my normal 25psi I have 0 issues.

Nice color on your Jeep OP! I went with a lighter 37 inch setup and haven’t had any issues.

Between 15-16 mpg usually for me. Mastercraft mxt’s are 69 pounds and the wheels are 26 so 95 total.
I do have the v6. The turbo 4 should yield slightly better mpg even with the 37s than the v6.

Pro comp 43s?
No they are gfx wheels from discount tire. 17x9+12. Almost went with pro comp 7069s but they shot up in price when it was time to buy. These were only about $100 a piece with rebates at the time I bought them (some holiday). Rear tires do slightly rub the rear liner but not bad enough to matter.

If you make it a habit of not turning the wheel while stationary on solid ground, you will have no issues.

Did you regear? I thinking about going to 4.88 when I add the lift and tires.

The rubicon with 4.10s do just fine in my opinion. The 8 speed is awesome. I do have the tazer to correct speedometer and other stuff, I have no plans to regear. Will even hold 8th if going fast enough on the freeway. It likes to stay in 6th at times but I bump it to manual mode and put it in 7th or 8th if on a long road trip. 8.5 hours to Moab this way and worked great.

What lift are you going with? I’m going to do the mopar lift before too long here. Just went with rough country spacer lift while I researched what actual lift to go with and they haven’t been bad.

I am currently running 35's and the electric steering has only "failed" me under certain conditions: tires at 8psi or less on tight mountain trails trying to crank the wheels when the rig is not moving fwd or bkwd. I noticed it is even worse on my buddies rigs with 37's. But that is only under very tight/low speed/high traction conditions. Would be nice to have hydro assist in those situations. If you dont hit those conditions, you may never notice it.

Was this on a 2-door or 4-door? They have different steering ratios.
