so I got a new set of rims and tires. Bigger tires to be exact. What psi should they be inflated to? I was told to use what the jeep says no matter what.
Any opinions

Jeeps psi is for daily highway use and likely to give the best mix of performance, economy, tread life. But it is not a "no matter what" pressure. Off road, especially in sand you may get better performance at a much lower psi.

What tires and what size? Do you know how to chalk test?

Do the chalk-test and/or try different PSI to see what feels best for you..
Some tires I've run at 35..some at 28.. I run my current tires at 30lbs..
When off-road I run them at 13-15lbs.

Problem is with a lower psi. I get that annoying tire low pressure gauge that stays lit

That is the downside. A programmer will allow you to change the psi thresholds.
