Hey Art:
I'm running 245/60-15 in front and 275/60-15 in back. I run 18PSI all around. There is a lot of air (volume) in those tires, 18PSI is plenty.

I grew-up in farm country, most tractors have about 5PSI in the back tires. When you have a lot of square inches of surface you don't need a lot of pressure. I run 100PSI in my little bitty bike tires.
