My 2018 RAM 3500, and my previous 2016 RAM 2500, both called for 65 PSI front and 80 PSI Rear!If you do test drive a 3/4 check the tire pressure. Not sure what the new ones come with from the dealership but my 16 3/4 had 80 front and rear. Unloaded you felt every imperfection in the road. Dropping down to 50 psi front and rear made a huge difference in ride quality.
