It’s a great idea…….as long as you do it properly: lift and gears.

This.35s on my factory 4.10 gears isn’t even really ideal. There’s no chance I’d want 37s on the stock gears.
I’ll be moving to 4.88 when my 35s wear out and I replace them with 37s.
This.
I have 35s on 4.10s with a Livernois tune. It's fine. It works. But I'd rather have 4.56s or 4.88s.
The quadratec link is interesting, but it doesn't make much sense. It shows the RPMs going 65 MPH in 4th Gear! At 65 MPH I'd be either shifting up to 6th or 5th if it's uphill. I have the 3.73 gears and have not had any issues in over 20k miles - that includes towing, cross country riding and in town driving. Re-gearing your rig is not an immediate necessity unless you do a lot of "Crawling" - op4.88 regear was a solid investment for me.
This should be a sticky somewhere:

The above link is a great resource and will help you decide the best gear ratio.

Doc Mike, what bumper are you running?No. I have a Sport S. I am running Rubicon take offs and a Terraflex spacer.
With 35s I regeared to 4.88. I am 6,000 feet above you. I rubbed at full flex and I wheel a lot.
You may be able to live with 35s in Florida.
33s were very livable.
I love the Rat Patrol theme. Here is A jk I did with RP in mind back in 2018No. I have a Sport S. I am running Rubicon take offs and a Terraflex spacer.

Doc Mike, what bumper are you running?
Are you an auto or manual? You will also lose 8th gear on the freeway, and likely never see 7th anymore. If you go over an overpass it will downshift to 5th to make it up the “hill.”
Reference: I’m on 3.73 and 35’s so 37s would only be worse.
So- definitely do it because 37s look awesome. I wish mine weren’t warrantied for 50k miles because I’d jump on some too. Mine is lifted and makes 35s almost look small.
Going to second this. Im in a Willys Sport S, Auto / Gas. I have the stock 33`s, 3.73 and tow package (not max tow, but tow package) and already I rarely see 8th. Im planning to go to 35`s when these wear out but will be saving ahead of time so that I can get regeared to 4.56 at the same time.
