Take it across a scale to weigh it axle-by-axle. DODGE has guidelines which work for loads within limits, and a Tire Manufacturer Load & Pressure Table will give the correct pressure number across the full range.

In this instance, a "generic" 3,042-lb LR-E table will get you close. Contact your tire manufacturer for specific pressures against loads.

Best tire life and tire performance is via correct numbers against a scale reading.

when you are towing set it at 80 psi. if you are empty about 55 psi rear and 65 psi front will give max life. slomover has good advice if you drive a lot with some load in between.
