Paul, I went to the address and looked at the chart. Unlike most in the
newsgroup, I am not an expert on anything. Anyway, the chart mentions
pressures "Unloaded". Is the same pressure used if re-inflating the tire
while on the plane?

I have an RV-4. The gross would be about 2000 max. There are two tires plush
tailwheel. The tires are 5.00x5 4 ply. Does that mean I should carry about
31 to 35lbs?

Thanks,
Joe

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.
