If you call Cooper and give them the running axle load they'll give you the suggested pressure.
For instance, I called Cooper and these were the inflation pressures for my old style load range D 7.50Rx16 Discoverer STT's

Loading
per
wheel
in
pounds PSI
2390 60
2190 55
2040 50
1930 45
1770 40
1620 35

Or you could just cover an area of the tread with chalk or paint and roll your vehicle forward and adjust as needed so you have an even pattern the full width of the tread.

Maybe we should add a new section to the forum so people can ask what pressure to run over and over and over and over and over and over and over and over and over and over and over and over and over and over?
