Question for BFG Mud Terrain owners
What PSI do you guys keep your BFG MT's inflated at on your Rangers? Im gettin new ones this week and I dont want to wear these ones out so unevenly like I did the last set.
The tires say 50 PSI max and I kept mine at about 45 thinking that would be better for fuel mileage but ended up wearing down the center of the tires more than the edges, from over-inflation per the weight of my truck. I later learned that you cant always go with what the tire says as vehicle weights vary. Duhh somehow I failed to figure that out on my own :S
So whats the ideal PSI to keep BFG Mud Terrain tires at on Rangers to get the best MPG and wear evenly?

The recommended psi is printed on a plate inside the drivers door.
32 is about as low as I would go, and makes a good standard cold psi in most cars.
I run my mts at 38 in the front and 35 in the rear. There's no science to my method, 34 was too squirmy (that's what the tire changer put in them) and 38 all around was too stiff in the back... 38f 35r seems to be just right! You'll have to play around with the psi and find out what you like.
Remember that as your tire heats up, so does the air inside it. As that air heats it expands, raising the psi inside your tire. If it says 45psi MAX the reason for that is because when it's inflated to the max when it's cold; that tire, at operating temperature, will be overinflated.
I would imagine somewhere between 32-40psi you will find where you're happy.

Thanks maybe I'll try 40 up front and a little lower in the back and see how that wears the tires.
I did 35 before and didnt like how the truck felt. Seemed like I was on the gas pedal more, like the truck wouldnt coast very well, thus hurt the mileage noticeably....
I like how 45 feels(nice and tight) but its wearing the tires uneven, so I guess 40 it is....
