Tire pressure??

[Frosty415]

It might be worth looking at what Ram HD tire pressures are (with HD tires).

I've run my 10-ply tires usually in the low to mid 40s range for everyday drivng. For towing heavy loads I'd go up probably closer to the 80 psi range. 80 psi for everyday driving got to be a little to harsh for me. At least for the crappy roads we have around here!

Gotta love these Wisconsin roads....right?? haha What area are you from?? I'm in Central WI - Marshfield area

I ran my 35" Nitto TG M/T's on 20's at 41 psi all the way around. Around 40k miles and they were all evenly worn at 6/32nds before I swapped them out. Not sure if that is the recommendation, but it worked and I'm running my new set the same way!

This is what I received back from Falken.....

Thank you for contacting Falken Tire.
First of thank you for providing all the information in your email! You saved us both many emails going back and forth.
So based on your OE information your vehicle's load capacity is 2601 lbs, our tire can safely carry that load at 49 psi cold(= 2639 lbs) you always want to meet the OE or exceed it by a little then be under the 2601 OE calls for)
It is at your discretion to inflate to a psi recommended by the vehicle's manufacturer when towing, just don't forget to set it back to 49.
We recommend checking your air pressure once a month and always after having your vehicle serviced, as a courtesy many shops will set your air pressure to OE which will cause you be run severely underinflated which will cause damage to the tire and possibly result in a tire failure.
I've attached a copy of our data book for your records, please feel free to contact us with any questions or concerns.

That was actually a pretty thoughtful response. Better than I thought you'd get. I think they added 5-10% of a safety factor on their number (just a hunch because that's what I'd do if I were in their shoes).

Down by Mad town, but lived in central WI for 10 yrs. Know Marshfield well, nice area!!

I think I confused myself a little with their reponse. Are they basically saying to run 49?? I was thinking of going with 44-46 but I dont fully understand what they are saying. They are talking loaded, right?? I asked them specifially for unloaded just normal commute psi

They are saying at your truck max load capacity thay 49psi should work great for you, well thats how I read it.
I would set them at 45psi empty and 50psi loaded and go from there.

That's what I thought. I actually checked them after work and they were at 54-55. I went down to 48 and it already rode better home. May go down more after a day or two and see from there.

^^ That's exactly what they are saying

When I had my 2014 1500 4x4 with 295/60r20s I ran 45 psi front & 40 psi rear. That worked great for me both as an unloaded daily driver and even when loading up for camping trips and 4 adults + 2 kids. The rear end sag looked more concerning than the slight tire bulge. That was 2 -3 days dry camping. I'd estimate about 700# of gear and about 700# in the cab.

For the 2500 4x4 I'm in now, I run 52/48 in 37x12.50r20 E Nitto Trail Grapplers. With 55 psi in the rears and a yard of topsoil, I had next to NO tire bulge. So I lowered my psi. I will probably lower the rears to 45 after winter is over.

As a side note, when I had my Jeep JK, I ran 30 psi all around, and she was a pig of a rig! Steel front & rear bumpers, full size spare, winch, Front D44 trussed, full steel skid plates (engine, trans, gas tank, & evap). Rock sliders too, but they don't really count since they were aluminum. Tires were 35x12.50r17 toyo AT2s and chalk test empty had the sweet spot at 28, but I just kept them at 30.
