I have a Wagoneer Series I that I think is ~6200lbs and it has the "Premium Group" option with 20" wheels and All Season tires equipped.

Is 36 PSI accurate for our vehicles for even tire wear, considering a much lighter Grand Cherokee and Wrangler recommended pressure is also 36?
I've seen some chalk test videos for the Wrangler being best a bit lower at ~32, and hoping that our Wagoneer's 36 is accurate for how much heavier it is.

Seems accurate. For reference the Ram 1500 is 36 and the Yukon XL is 35.

The RAM 1500 is actually 55 front / 45 rear PSI. I only know because I traded in my 2019 RAM 1500 for the Wgoneer haha
People on RAM forums stated it's too high for uneven tire wear but 52/42 is even wear.

So with the Wagoneer weighing 6200lbs = 1100 more lbs than the RAM, I wonder why it has 36 recommended which is the same for vehicles over 2000lbs less

Escalde and Yukon are 35. Navigator and Expedition are 35-39 depending on tire size. Wagoneer at 36 seems pretty sensible to me. Maybe pickups are different since you load them and use them differently. I wouldn't overthink it. Enjoy the new rig!

I would check the film on the bottom of the driver's door. It will give you the tire pressure settings.
