Ha dude half the people on that site had to replace the motor or lifters or timing belts... I mean regardless, 200+ is impressive, but half the people on there replaced it before then.
all of the motors in these trucks are good, the 3.9/5.2/5.9 have just had more time to be proved good, the 4.7 has only been around since 2000(at least in these trucks) so still waiting for time to give us more good hard evidence of how long they last.
I had so many things go wrong with my 3.9 i would never consider it a good motor, but its just my experience, if a lot of people you guys know had good experience with it, I can see why you guys would consider it a good motor in your eyes. But from the amount of problems I have (and I take care of my stuff) and the problems friends have had, I wouldn't ever say it was a good motor.
be nice to your 3.9 and it'll be nice to you, got over 130k problem free miles and wouldn't hesitate to drive it anywhere, minus offroad and such being a 2wd
the numbers on the door though are for that size which is usually 235's i just go with 40 psi in my 31x10.50's which a lot of daks have on them
If you have a bigger tire than what the factory pressure rating is rated for, you will want to go with less pressure. The sum of the tire pressures times the area of the footprint of each tire should equal the weight of the truck, so if it has a bigger footprint you won't need as much pressure (but not much less, like maybe about 1 to 3 psi)
So I would want to go with 27-30 psi for the bigger tires even though it makes them look low? I appreciate all of the advice I am getting but it seems like there isn't one real answer. I hear to keep them at 35 like the door says, some say to do it at 40 and some say do it lower like 27.
