For example: Your Vehicles weight with a full tank of fuel plus the load capacity of passengers and cargo. Lets say yours is 3700 pounds.
3700/100= the recommended cold PSI is 37.

dont do that. just chance that works on passenger cars, but not so much on a 80,000 lb semi. or maybe a 10,000 lb monster truck (those run 4 psi). see the problem with that? the psi is determined by several things, not just load. every tire that that can fit on these cars will work just fine at 36 psi. 35 is generic for all tire guys.
nitrogen is used mostly because of the reduced expansion, but also because of the larger sized molecules to reduce air escape.
and comrando
Boiling point????? what are you doing to your tires???
