Interested also.

 

i run 36. lots of cars ship with higher psi due to the amount of time it sits around, the higher psi helps keep the tires round.

 

Ours was delivered at 51 psi. It took us a couple of days to notice it and we only did when we were flipping through the screens. I immediately took ours down to 36.

 

I run 36

 

I concur, 36 psi in factory GY 265/50/20's.

 

I got mine with 44 all around. In past years I would put a little more in the front because of the added weight of the engine. On this one I look at the distribution and it's about the same front and back, so I have left them at the delivered pressure for a while. Ride is good, handling is perfect, after 15,000 miles I see no apparent wear patterns at all on the tires. I may just leave it there. I will rotate pretty soon though.

 

Ours had 49psi when we first got it. I lowered it as well and depending on the temp they fluctuate between 36 and 38 psi.

 

Thanks All!!! May increase back to 44PSI range. Should ride a hair tighter and increase mileage.

 

I've always had great luck with 40 psi in truck tires. I tend to use that as a starting point.

 

I run 40 psi, but in winter time I do less

 

this is a pretty interesting topic. so far I run 37 psi cold. that tends to equal 39-40 psi at operating temperature driving around town. is there a reason to run higher pressures in these tires?

 

i always assumed higher means better gas mileage-

But PM tried it and says "busted":

None that I know of I run 36 cold and same as you they build up to 39-40
STEVE

 

36PSI COLD in my 2014 R/T, in the winter I run 38 Cold for personal preference.

 

I run 40 in spring & summer, 36 for fall and winter.



Interesting you run higher pressure in the winter... it's not that much difference, but may I ask why? I'm not that far from you in NY and between the snow, rain and potholes I tend to run slightly lower pressures in the fall and winter for the extra grip and added cushion from potholes (too low can obviously bend a rim).

 

I run 38 and they roll up to 41 when hot.

 

Unless you've installed LT tires, run what the door card says -- testing while cold. I'm also surprised this isn't an item on the delivery checklist -- especially with all the over/under-inflated issues throughout the years. You'd think this would be one of the first things they check. However, they are always out of whack.

 

My wife noticed that our new RT had pressures of 47psi on three tires and 49 on another. (She was playing around with the controls when she discovered the tire pressure display which is really nice...) She was concerned about the difference and mentioned it to me. I knew that 49 psi had to be high and checked the numbers on the door, which say 36psi is correct. I took them down to 38 and am a little miffed with the dealer now...

 

My citadel came the same way. many car manufacturers will overinflate tires to prevent flat-spotting during transit and while the truck sits on the lot. Sometimes the dealer forgets to adjust to the proper pressure before delivery

 

Mine were 46 all the way around at delivery and I brought them down to the recommended pressure.

 

Smells spammy to me. Shame on PM? Kind of a pointless post.

 

have a 2021 durango srt 392 with 295/45zr20 bsw performance tires. Manufacturer recommends 33psi (51 psi max). I start at 36 psi to allow for bleed down over the course of a year.

 

You only check you tire pressure once a year?

 

check several times a year, but rarely need to re-pressure more than once a year.

 

Yowzers! In the winter alone, mine can lose a couple/few pounds in a month or 2!

 

I had a '22 rental R/T recently and the door placard said 33 psi front and 36 psi rear...so 3 psi less than what my 2014 says for the front tires...wonder if Dodge did that for ride comfort? Or handling?

 

Possibly for comfort, as I think some of the newer R/Ts are coming with run-flats?

 

I just manually checked with a Milton tire gauge and I have 35/37 Front and 40/40 Rear.

Even looked at the display and it was very close 36/36/ F and 40/40 R.

 

FWIW this is what the FSM states for the TPMS.

Tire pressure will vary with temperature by about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure (placard pressure). This is defined as the tire pressure after a vehicle has not been driven for more than 3 hours (and in outside ambient temperature). The tire pressure will also increase as the vehicle is driven? this is normal and there should be no adjustment for this increased pressure. For a system fault, the system will return to normal once the TPM module receives a valid transmission from that sensor location.

TPM THRESHOLD PRESSURES

To determine the pressure thresholds for a vehicle, refer to the Tire Inflation Pressure (Placard) Label found on the Driver's B-Pillar, then apply the placard pressure to the following table.
