37s air pressure

[PL1HD1]

Any one running 37s on a HD ? If so what air pressure are you guys running ? Starting to experiment with mine to see what rides and handles the best .

Experimenting myself... Running 37 Nitto RGs on Stock AEVs. 45 in the front 35 in the rear unloaded and not towing... 45 towing my 5500lb boat. So far so good.. just annoying with the low air pressure light on the dash.

They keep changing it every time I rotate, but my baseline goal was 40 all around, bump 10 rear towing heavy, and that rode well. Last time Chevy rotated they put them at almost 80 psi and it rode like hammered shit until I got home and dropped it.

Gasser 37" RGs.

Load comps:

Seems really low to me! I would expect 50 psi on the low end and I'd run near max towing, whatever it says on tire sidewall, so 65-80 psi if they are load range E.
