2016 Ram 2500 Tire Pressures -Need Ram Owner Advice

Hi All,

Recently upgraded from a Ram 1500 5.7L to a Ram 2500 6.4L 4x4.

Truck is awesome, don't even need tow/haul mode pulling my 7000 lb camper. Night and day vs. 1500, blah blah lol. I'm averaging 19 mpg hwy, 14 mpg around town, 11 mpg towing.

My only complaint is the tire pressure monitoring system. The door sticker says 60psi Front, 80psi Rear. LT275 70 18 Firestone Transforce HT tires.

Well I mainly use the truck to tow our camper and the rest of the time it is unloaded and empty. At the door sticker pressure and empty, you can imagine the ride is less than smooth.

I am currently running 55 psi front and 50 psi rear and the ride is sooo much smoother. But now I have the TPMS light on. Even at my current lower pressure and pulling my TT, I am still at an acceptable pressure according the Firestone Tire loading chart I have. My payload is 3180 per yellow sticker.

Apparently Ram used to offer a Light Load switch for the TPMS on 2013 and prior 2500s.

I took the truck in to the dealer for help with this and the service guy took me aside and said I'll take care of it (wink,wink) like he's done this before, then he comes back 15 minutes later and shows me some paperwork dated April 2016 from Chrysler telling him that he can no longer change it.

I think it is ridiculous that Ram requires full load pressure in the tires on 2500s (3500s don't have this limitation)

Was anyone able to get the dealer to reflash the TPMS to lower thresholds?

What tire pressures are you all running?

Thanks and sorry if this has been asked before.

I run 70 front and 80 rear, all the time. It's not a Cadillac... it's a 3/4-ton pickup. I get 21 mpg hiway and about 16 around town. It is my daily driver but my commute will end on October 18... my last day I have to report to work... ever...

Hi schrederman, my 1500 Ram ride was a cadillac lol. I know the ride would be stiffer with the 3/4 ton but damn at 80 psi and empty it will rattle your fillings out!

How is your tire wear?

Tire wear was even on the Firestones that came on it. It now rides on Michelins and I'm still using the same tire pressures. It's a '14 and now has 44K miles. The Firestones didn't last but 35K miles. So far it has towed about 12K miles of that 44K. Delores and I lived off of 1488, between Conroe and the Woodlands for a while. We liked it there, except for the traffic...

No consolation probably but I have never been able to use the "light load" feature on my 2013. It's there just will not switch when I push the button. I do my own filter/oil changes so don't get into the dealer to look into it. I actually don't mind the ride.

35K miles seems low. If I ran 80 in my rear tires, the center tread would be bald in no time, even with pulling my trailer with 900 lb tongue weight. Not to mention how sketchy it would feel in the rain...

I moved to Conroe a couple years ago, it is getting even busier since I've moved here. Want to buy some land in the countryside now. lol

Lower the pressure and put a piece of tape over the light. Done!

Haha! Pressure is lower now, problem is not only is there a light but it beeps at me and displays in the EVIC, requiring button pushing every time I start it up. PITA

Try raising your pressure slightly. On my Silverado I run 55 psi front and rear to keep the TPMS monitor clear. Any lower and it will alarm when the tires cool overnight.
