Use dictates equipment.
Nothing wrong with Duratracs. I have heard several good comments on them.
The criticism I have heard {secondhand} is a relatively weak sidewall that can be prone to cuts and punctures.
I also don't think the 19" version is available in an E rating. That might be a consideration if you mod the truck as mentioned in your other thread.
You really can't air down 19's as well. Might or might not be relevant for your uses.
You could also consider doing 18's by going the much cheaper route of LR3 18" wheels with a 1.25 inch spacer. I ran this configuration for 45K miles before going to compomotive 18's and had zero issues. I found my LR3 wheels on craigslist, and with the spacers was into them for approximately $600.00 and a little bit of grinding time on the front calipers.
Actually, knowing you're in Houston, as well, I will make you a great deal on 5 LR3 wheels if you want to consider that route. They have been there and done that, and they have the gouges and rock marks to prove it, but they are perfectly serviceable. My wife would love to see me cull my collection of Land Rover wheels as they have just been sitting in my attic for 2 years at this point.
Spacers are available here, if you go that route.

@Socialseb83 since you noted in your other posts that you're going to be potentially spending money (in your stack-ranked / prioritized list of spend), and that you want to "go off-road", you're always going to be better going for a tire with more and stronger sidewall and more load capacity and puncture resistance. If all you're ever going to do is go on dirt roads, something like the Duratrac or Continental CrossContact or Bridgestone Dueler Alenza that are all Load Index 111, 50 psi, SUV tires will be more than plenty.
But I agree with the other forum members above, if your use case dictates going on harder trails, potentially getting into some rock crawling (you mentioned sliders and front/rear bumpers in one post), then you'll be wanting 18" wheels, and beefier E-rated tires.
In short, if you just want to look good but be a liability on the trail to yourself and others from having sidewall punctures, throw a set of Duratracs on. If you want to be useful and safe off-road, then invest first in good tires/wheels. Your use should dictate the equipment.
1. Light-duty off-roading: 19" wheels (or bigger) with something like the Duratrac / CrossContact / Alenza. But if you have those 6 ply SUV tires, you probably don't want to be putting yourself in situations where you need sliders, bumpers, and armor.
2. Actual base off-roader: 18" wheels with E-rated truck tires, and a shovel and maxtraxx and first aid kit in the back plus driver and first aid training.
3. Serious off-roader: Everything in 2 above, plus bumpers, winch, roof rack, etc. Pros: Capable. Cons: Expensive.
I think you need to be honest with yourself what you're planning on doing with the truck. There is nothing wrong with "making your truck look cool" but don't confuse that with building an off-road or overlanding vehicle.
You mention budget constraint. You'd be better off doing the wheels and tires now and getting some driver training and then skipping the rest of the truck additions you were planning. My two cents. I'm sure others will have different opinions. Regardless, welcome to the clan and good luck with the build!
