Thanks for the leakage comments... but anybody know about the
proper tire pressure? Or is that a mystery?

45 psi for mains and 55 psi for the nose. Use six ply tires for the
mains. Check pressure 12+ hours after initial inflation and add air
if necessary. After that, pressure loss will be due to
leakage/diffusion.

The 70 psi nose tire pressure suggested by another poster is not only
needlessly high but is over the maximum pressure specification for
most 10x3.50-4 tires (1). Another poster's comment to "blow 'em up
until the sidewalls come off the ground" is, of course, idiotic.

1: The ply rating is an indication of tire strength and does not
necessarily specify the actual number of carcass plies within the
tire. The term is used to identify the maximum rated static load
capability and corresponding inflation pressure applicable to specific
operational requirements.
