All you people who think SelecTrac (Full time 4wd) is pointless. This is a perfect example of when it is useful. Accelerating around a corner in the wet at low speed. (when the engine can put more torque to the rear wheels)

Uh, I have selectrac, that's a small part of the reason I'm concerned about things. When it's rainy or wet roads, it's always on.

Any weight in the bed?
You say it’s cooler too, wet cool roads have a lower adhesion point.
As mentioned, traction control on or off?
Traction control on, about 80 pounds of fly fishing gear and hiking gear in the back.

I feel like it should help. All of this may be moot point though, took the truck up a muddy forest service road that we have done in the spring under identical conditions and in 4H auto my ass end was all over the place. 4H wasn't much better if at all. Dropped in into 4Lo for a climb up to a point and got a service 4wd error. Got that error Everytime tonight. Trying to go out of 4lo and 4Lo stays lit and it also lights up 4H until I power cycle. I'm not sure if this is related to the slop I was experiencing but something is really messed up now.

Yup there you go, your gut feeling was right, something is screwed.

Oh wow. Ok. Well that's a problem.

Have you tried turning it off? If its the same, maybe its not working right.

LOL, Discount tire @Discount Tire is wrong, rims width is 8.5-11" it also pretty comical how many times it has been repeated on here.
Maybe you don’t know what your taking about. ?

Prove me wrong, you cannot find a single manufacturer that makes a 315mm or 12.5" wide 35" or 37" tire and lists a 7.5" wide rim as suitable to be mounted on.

JPP Mopar off road wheels (and Jeep factory Xtreme with 35’s) are standard factory +12, thus they do not stick out and create all sorts of problems with wear, tear, and greatly increased stress loads on entire front end, buying yourself a ton of problems. His Rubicon is equipoed with the new (2018 and up) factory standard Advantec M210 wide front axle, so the wheels and tires are already moved out, a bit. Also, with 37’s, you’re buying extra trouble with rubbing/scraping, particularly when encountering obstacles off road. Now, for a mall crawler, you can get away with some deviation from factory stock +12. Depends what your goal is.

My jt has noticeably less traction than my 2dr jk did. But my old F150 would get loose in the back too. There's a physics lesson somewhere that could explain this if I were only smart enough.

Take two popsicle sticks and break one in half. Now lay the long one on a table and the short one on a table. Set a 9 volt battery at one end of each popsicle stick. The sticks represent the frame of a jeep and the battery represents the weight of an engine. Now pretend your a tiny ant and you want to pivot the end of the popsicle stick. Which popsicle stick will be easier to pivot?

Neither, as an ant couldn’t move a 9v battery. At least not the ones where I live.?

The US military ‘means business,’ and has no interest whatsoever in pursuing ‘mall crawlers,’ thus note (what appears to be) the standard Stelantis wheel offset of +12, juxtaposed to a bunch of teenager brodozer negative offset. Food for thought…

But, it all depends on what you want! Mall crawler brodozer vs/ ‘The Real Thing.’

JM2C, IMHO, and YMMV!

You are absolutely correct. But that doesn't mean it won't work.

It means that your margins are thinner. If you are going to run the tire up to maximum or minimum rated pressure with maximum load it may not do well on a 7.5" rim.

But something doesn't work perfectly at 8" and then suddenly self destruct at 7.5".

you can adjust how wear across the tread occurs by adjusting tire pressure down when running a narrow rim.

Back when I was in college I worked at a Saab dealer as a used car tech. The 9000 turbos back then had 205/50 tires on them.

My old 99 had 165/70 tires. I shoehorned 205s onto my skinny wheels and drove like that for years. It was not ideal. But I ran the car at Limerock with the Z club and Porsche club regularly with no problems.

In the winter I went back to studded 155/75-15 Vredestein snows. It was quite an adjustment. ha.

This is great news. Depending on the neanderthal "parts changers" working in a Flat Rate service department to properly diagnose and fix an intermittent problem is a recipe for failure. (The dreaded "Could not duplicate")

If something fails so the problem is persistent, its much more likely they will be able to fix it.
