On Street What Do you Set Your Tarz PSI at?
And does airing down a little effect gas mileage?
Why does Jeep want you to set them so hard?

Not just the placard on the jeep, it's all the tire mfg's and shops. Every time I go in to discount tire for the free balance/rotate, I leave with the tires up at 40+ psi. As noted above, it depends on the tire size (bigger tires can get away with running less psi), the tire load rate vs the vehicle weight (C load on a heavy rig vs E load on a light rig), personal preference, whatever else. 30 psi is generally a good place to start doing the chalk test, then tailor it to your specifics.

I run my stock Rubicon tires at 37 psi cold pressure, as indicated on the door sticker.
They wear evenly, and the first set lasted a little over 76,000 miles.

Are we talking cold or hot? Cold start mine are at 34. By the time I'm running them a bit they're up to 36-37. At least that's what the PSI indicator on the cluster shows. I too have debated dropping them a little
