We aired down to 18psi for the terrain we were tackling. The truck handled surprisingly well and is super capable! .... but felt a bit dangerous.
When we had the truck flexed out the 255s were rubbing. Wouldn't the 285s be more prone to rubbing? I hadn't considered the idea of just keeping that size, really. Jarrod, did you do a 'camel cut' to the truck? From what I saw, it'll need some help like that.
Just trying to help think of things for Ryan, and appreciate the feed back.
One thing to keep in mind is that 285s are actually a smaller tire. The 255 has a huge sidewall and measure out to almost 34". I didnt like them and my next step was the 285s. The truck does have a learning curve though, that is a good way to put it. There is a little getting used to but like Ive told Ryan and WhatRoad has mentioned, its time to sit down and figure out what exactly the truck will be used for. For me, the 3 link was the ticket but it might not be for you all down in Texas. I have not cut any sheetmetal on the truck at all. It might be worth considering that. If you look at a DII vs. the DI, youll notice larger openings for the tires. The front is big enough but the rear opening is pretty small. Im not too sure what the "Camel cut" is but I have heard of it before so it might be something to think about.
It might be that it is too tall and if that is the case, you could pull 1" from total height very easily by removing the spacers. With the SG set up, running a sway bar in the front is impossible leaving only a rear as an option. I was looking at upgrading to 285s (smaller in overall diameter and wider by an inch) and make up a set of check straps that are slightly shorter than the available droop, front and rear. I had an old recovery strap that was not safe (due to age) for recovery but could give its life to make check straps. Something like this:
They would keep the truck from rolling through its complete travel, slightly like a sway bar.
Again, its up to what the trucks use will be. You wont need to completely replace all the suspension, like springs, as 3" is a nice number to have in total height, if you decide to pull the 1" RTE spacers. The other thing to remember is that the front set up needs 3" of lift minimum. Anything lower than that and you are going to need to swap out to another, more stock 4 link style system and sell the set up to WhatRoad. Here is some good reading on the system:

Note that you have a better, upgraded center link with massive heims on both ends. The stock SG center link was no where near as strong. Try pulling the spacers and see how the suspension reacts then. It is definitely not an "expo approved" system but it is definitely well built and would easily offer more trail capability than cranked front links can. I bet pulling those 1" spacers would switch its attitude.
