Ram 3500 DRW tire pressure

And before someone asks.... It's a MegaCab which is why the payload is so low for a DRW.

Payload is 5,800# or so and even at 16,000# GVWR for the 5er is 3,200# well under the Max Payload of the TV, Look at the yellow sticker, that is tire PSI for MAX payload, if it shows 65 pst you might look at running the rears at 55 to 60 psi and the fronts at 65 psi.

Look at the tire side wall an what is the MAX weight rating at 80 psi? Keep in mind you have four tires supporting that weight, if your empty rear axles weight is even 3,500# and the pin is 3,200# total is 6,700#. That means 6,700# / 4 = 1,675# per tire, so even de-rated to 2,500# per tire dual each tire is carrying 900# LESS than rated for at 80 psi, making the tire over inflated for the load carried.

At 80 psi inflation with the assumed load your tires look like the profile on the right side of the picture.

Well I guess I'm not at 80 all around.... Fronts are 80 and rears are 70-75.

What year and what is the GVWR and rear GAWR? If newer than 2006, what does the Payload (Yellow) sticker call for for MAX payload.

I feel that you are running your tires over inflated for the load carried, resulting in loss of traction both for getting going and braking.

The more air; the more weight they can handle. B-52 tires are aired up to like 450psi. Look how much that thing weighs when loaded and how many tires it has.



I'd run them at max psi. Other wise; is X pressure enough and correct?

Chance for a blow out or no chance?

Rears should be at 65 for dual wheels and front at 80 psi

Well I guess I'm not at 80 all around.... Fronts are 80 and rears are 70-75.

Since you are going up significantly in weight if anything tire pressure would go up. But since 80 psi is your max tire pressure (unless you are running 19.5s) you are already there. If anything you could consider adjusting your pressures down a bit.
