With a true 37" tire, you should turn about 2,186 RPM at 70 MPH.

I got on the freeway after these original posts, 2100 is closer to the truth as opposed to the 2k I originally said

Good looking setup.
What lift do you have?

Zero issues with my Yukon 5.13 gears. Drove over 5,600 miles this summer from PA to Yellowstone and back, towed, off-roaded.

None at all. Over 8k miles on them so far

Go with the 5.13's, unless you drive like a pissed off 16 year old and routinely do 90+ on the interstate... The extra weight of the tires and even less aerodynamic leads to the deeper gears. Plus this engine likes to rev up, Peak torque is right around 2300

I see my Jeep as a brick, it doesn't do interstate well, and no amount of gearing/ect... is going to make it shaped less like a brick. I'm find doin 70 for the short interstate stretches I drive. Plus I do plan on towing with it.

It’s been a year, how do you like the tires. I was thinking about making the switch to save some money from my KO2s

ps- did you ever regear?
