Default Tire width - 13.5 or 12.5?

Currently I'm running 37x13.5x17 Toyos. Gotta get new tires probably by summer and was wondering should I stay at 13.5 width or go 12.5?

Any pros/cons to either or just simply a matter of aesthetics. Aside from looks I figured the only pro I could think of is a wider wheel base and this greater stability.

Yes, greater stability + more traction. Also, more weight and strain on drivertain.

I am goin' to a tall and narrow rubber since the Jeep is also my DD, I dont like weaving, struggling, and driving off the lane when there's a crown on the rode and I dont like hydro planing everytime I hit a pool of water (even at slow speeds) so the wider tire would be more pronoun. Now, a good thing about wider tires on a small width wheel is that it acts like similar to a beadlock and will stay on the rim a little better than a wider rim with almost same width tire. I have been to 12 PSI with my 15x8 and 35's with no issues. Of course, I want even more traction and a larger footprint so Im going 37x12.5 on ATX slabs.

I think my 35x13.50 toyos handle better than my 33x10s handled

A narrower tire will do better in deep mud, and cause less stress on the suspension components. They are also less likely to grab ruts in the road and hydroplane in the rain

If you put a 13.50 and a 12.50 wide tire on a 8 or 9in rim you can't really tell the difference.

Hmm. My buddy's 13.50 toyos definitely sit wider than my 12.50 nittos. If we park beside each other you can see the difference...

I guess it depends on brands, I was gonna add that, cause my 1250 coopers were really no different than my toyos. And pro comps were the same as as my toyos aswell with no noticeable difference.

Yeah I'd be comparing Toyo to Toyo. Really happy with my first set and so didn't want to change brand hoping they are consistent

Yeah that's a pretty big issue for me as mine is a DD. I remember the first time I hit a big puddle of water next to the curb - sucked me right into it! And the rut grabbing is a PITA right now.
