Just spent quite a bit of time reading about tires here and looks like I'm going to go with the BFG A/T 285 75 16's. My question is do I need to do any suspension Mods gonig to a bigger tire and what psi are you guys runing in these tires?

Should fit with some trimming at the front and crank the bars up.

Agreed.
You dont have to do any trimming if you crank your tortion bars. Dealer cranked mine 6 turns and they didnt rub at all. I did however have to do some trimming when I bought new rims. The factory wheels are 16.x 6.5 and generally not reccomended for 285's. I ran them for years on stock wheels with no problems as did a ton of other people. My wheels now are 16x8 and I had to crank some more as well as trim a little bit.
I generally ran them at 60 or so PSI. Some run more and some run less.
The BF A/T's are great tires.

Well you need to ad a signature so we know what you have for a truck.. If it's new style GMC like mine, I'll send you a drawing I did that shows just what I trimmed and bent and cranked. If it a chevy it's a little different but basically the same. You may have read here the each truck is a little different I would suggest cranking you bars a inch over stock hight. Bending the front of the drivers side wheel well bottom edge forward with a heat gun. Getting your tires then if needed trimming the front valance or bummer cover with a saws all when the truck has the tires on so you cut it just right. It's really is just a little section on the edge, It sounds worse than it is.
On the chevy's, some guys need no trimming.

if you crank your torsion bars you shouldnt have any rubbing with the 285s on stock wheels. i have 265s and 1.5" crank on my tbs and i can tell if i had 285s there would be no way for me to rub, the closest thing for it to rub on is the front valence. but if u decide to no crank you will probably just have to trim your valence and a slight chance some of the wheel liner but not much at all.
are you going with the e or d loads?

the 285 really needs to be on an 8 inch wheel. You are really sucking in the beads by putting it on a stock wheel. That changes the flex area of the tire and pulls the shoulders of the tire up, so you don't get the foot print that you should with that tire. Also, it puts a lot more wear on the center of the tread, because the tread is not laying flat on the pavement.
Everyone has a different opinion of what looks good. I personnally don't like that sucked in look, I think the 285 looks much better on a wider wheel.
One other thing to consider, is that you are putting a lot more stress on the bead area of that tire, and if you are towing heavy, you could break a bead before you get the tire worn out.
Cranking the torsion bars up will make it ride rougher as well.
