The 60 psi is probably the max pressure for max load. I run a similar size tire and just keep it above the point where I get the low tire warning. At 60 psi the tire will be hard and will not give you as comfortable of a ride as it will at lower tire pressure. You might get a little better mpg but the trade off is a stiffer ride. You can safely run at lower pressure as long as you are not overloaded. Many tire failures occur because of running a tire at too low of pressure and it getting hot and failing. I do not think there is much danger of this at 37 to 40 psi
edit: I just saw that Robby said pretty much the same thing as I was posting. You can't get better advice than from Rob.
