Tire Pressure Question

[Vinjack98]

Anyone out there running 35x12.50x20 nitto trail grappler MT's? I am looking for some tire pressure reccomendations for both on and off road?

I had them for about 2 weeks in the 18 inch version and they were the worst highway tires I have ever had for a truck. Tried pressure from max psi cold to 10lbs below just for grins with no change actually a little worse the lower I went. Discount took them back.

Hope you have better luck with the 20's and a shorter sidewall.
