My wife and I just purchased a new 2018 Jeep Wrangler JL Sahara Unlimited. It’s the first Jeep we’ve ever owned. It already has a lift kit and 35x12.5R18LT load range E tires. We ordered a new bumper, 8000lb Warn wench, electric running boards, hood deflector, window deflectors, grab handles and a few smaller things. Hopefully everything will be in sometime next week.

The dealer set the air pressure to 40 psi and I believe that’s way to high. What have you guys done that have larger tires about TPMS? What tire pressure would you run?

Can't help you with the air pressure as I don't have my JL yet, but that is a nice looking Wrangler. Congrats and welcome to JL Wrangler.

Welcome to JL Wrangler. Agreed, 40 is too high. Do a chalk test to determine what your tire pressure should be, but I imagine you'll find the optimum pressure to be somewhere around 30 psi:
