im running toyo MTs on mine and also have used them on multiple trucks in the past, after trying multiple brands of mts i ended up using the toyo MTs ever since trying them one time, ive had them lats almost 80k miles on another previous gmc sierra denali pickup, i just rotated them every oil change to even the wear, if you dont roate them the fronts wear out alot faster and will get uneven wear and thats when you will have loud road noise, if they get rotated the road noise if very minimum and i can barley hear it. for the raptor i like to run these tires at about 38 psi for good road comfort, anything above 45 psi on these tires even though you can go all the way to 80 psi on them i wouldnt go over 45 because it will be very stiff and feel all the small road imperfections as these are ten ply thick sideway tires. ive never deflated them driving through mud or other off road types, but if your in some sand or other areas where deflating them will benefit you then i would do it if you have the means to inflate them on the drive back. hope this helps/
