I know the decision on what to run these tires on this truck are all over the place. I just used my own knowledge on the subject and did a long search here to come to 45-46psi. That seems to be where a good amount of people here are running theirs with good information to back that choice up. Although it really is a hard question to answer.

Absolutely. I've been reading your posts. Very good info. All over the place definitely describes me. I deflate and inflate about once a week for the trails, so I've just been experimenting. I liked 45 just fine, until one day I had the opportunity to ride in the back seat. We did have 4 adults in the car, and maybe I can throw my wife under the bus for her driving a bit, so there are definitely other variables at play, but it felt really harsh back there. So the following weekend I went down to 39, and the journey continues. Of course i haven't been in the back seat again, so i can't really say if it's better. Speaking of back seats, I just removed mine yesterday. I'm seeing about a 0.2 improvement in mpg. Tomorrow, I'll be hitting the trails again, so I'll air back up to 45 and see if I can squeeze out a tiny bit more.

Oh man, didn't even think about the rear seat passengers! lol. Its just me the wife and three dogs and they never complain. We do occasionally carry 4 people and will be listening for the comments on ride quality. Thanks for the info @Greasecar1
