Hi another tire pressure question. I just put some 35x13.5 r20 ridge grapplers. The tire place put 60 psi front and 80 back. Was wondering what you guys are running not loaded and pulling a travel trailer. Also what are the thresholds for the front and back. Just don't want to wear on even this new tires..its a 2018 2500 6.7 cummins. Thank you
