I cannot find the correct tire inflation pressure for my 2004 MT 170 Karavan trailer. Can any one help?

If they are marked Load Range B tires, 35#
If Load Range C, 50#
If Laod Range D, 75#
Most good trailer tires are Load range C or D.

The Goodyear trailer radials under my Montauk don't have a
letter load range. They do have a maximum inflation pressure.
I'd suggetst 5-10 pounds under the max.

I have never seen a tire yet that didn't have maximum pressure ratings molded into it, usually in the form of
MAX LOAD XXX LBS AT NNN PSI
The general sense here is you inflate the tires to the maximum rated pressure when cold--very cold, as in first thing in the morning cold. Then as Chuck says, maybe back off a pound or two ( or 5?).
I have always wondered about this situation:
If a tire is inflated to maximum pressure when cold, should the pressure be checked again when the tire is hot? And if so, should the pressure then be adjusted (usually lower) when hot to conform to the maximum?

Inflate cold to the amount on the tire wall as Jimh says, and leave it. If for example, it says 900 lbs @ 35 psi then the tire will support 900 lbs at 35 psi - not 34, 33 or anything else. That is what got Ford's Explorer in trouble; they tried to lowert the pressure for better ride and handling and lost weight carrying ability.
