Towing advice- 2019 Ram 1500 Bighorn 4x4 5.7L

I always run max pressure stated on sidewall for towing.

They are 10 ply. I just called falken and gave them all my details and they told me I should run at 48 PSI front and rear. They wouldn't tell me a pressure to run for towing. Any ideas?

If it helps, I have a '16 Rebel with E rated tires. The Rebel recommended PSI is 55 front, 45 back. And I tow at this setting also.

The best way to determine the correct pressure is take it to the Cat Scale when fully loaded and get the axle weight. Then use the Toyo load tables that were referenced previously.

If you just want a quick idea go to https://tiresize.com/pressure-calculator/ enter your door placard pressure and the two tire sizes and it will tell you the pressure to run to match your OEM GAWR.

Here’s a tire pressure chart for your size tires. Find a scale and determine how much weight each axle is carrying when towing the trailer.

What’s the max cold PSI on the sidewall. Run it.
