Tire pressure

2022 F350 6.7 crew LB
The yellow tire sticker on the door pillar says 80psi rear and 60psi front cold.
Why only 60 on the fronts?
Not sure what to run the fronts at when towing 12000 5r.
No picture right now , you'll just have to take my word for it that's what it say's.

Thanks for your response in advance!

"Only 60" makes me chuckle...
I recently had some body work done on my Silverado 2500HD. When I picked it up, I asked the guy to check my tire pressure because I knew I had a slow leak in one tire. Several minutes passed, so I went outside to check on him and saw that he was letting air out! I asked him why and he told me they were only supposed to be at 35 psi. Yes, I explained this truck is no passenger car and then I showed him both the pressure rating on the tires themselves and also the door label, 70 rear and 60 front for my 3/4 ton Chev.

60 psi in front is where your HD tires will steer and ride best. The 80 psi in the rear tires of your 1-ton is because that is where the load stress will be greater.

You do have some flexibility in anywhere in that 60/80 range. Some people like to run with a lower pressure in the rears unless they are towing/hauling. Just remember to air up before you hitch up.

Ford subscribes to the SAE trailer towing standard and they have to meet the requirements of their understeer test. More pressure in the rear than in the front will help them pass that test and ensure that the truck doesn't prematurely oversteer and become unstable.

If you were to look at a tire manufacturers chart for the specific brand, type and size tire that was originally on the vehicle, you would find that the pressure specified on the chart matches or exceeds what is needed to carry the Maximum Gross Axle Weight. The only reason they would have to increasing the pressure above what is needed to carry the GAWR is, as noted above, for handling characteristics. They cannot go lower or they would have to lower the GAWR.

My 3/4 ton specifies 80 psi in the rear, but I only run that much when there's a heavy load involved. 80 and empty it rides like a pogo stick.

As a comparison, I run 65 psig front (per side door sticker) and 80 psig rear (tire stamped cold inflation pressure) towing my 15,000 lb fifth wheel trailer on my 2016 F350 6.7 diesel long bed DRW.

Yep; the 60 front is likely fine (mine is 75 but my DRW probably has smaller tires). The 80PSI rear would only be at max load (if that) - empty, there would be far less load on the rear tires than the fronts so pressure should be less than 60psi. ....tire manufacturers' load chart and a weigh scale or a chalk test would be better indicators than the yellow sticker IMO. No way I'd run 80psi on the empty rear, probably 50- 60

My Tremor sticker says 80 on da house! If I'm not towing I run 70.

For us dumbasses not in CA, what does "on da house" mean ?
I've been eyeing the F350 Platinum Tremors. Interested in the payload rating of such a high optioned Powerstroke 1 ton. Care to share your yellow sticker/CCC sticker ?

On da house means all four tires. It's not a hip Cali phrase yet as I only just made it up.

As I recall my payload is 3350. If you don't do much off-roading then a Tremor probably isn't worth it. I do quite a bit so it was worth every gram of platinum. The front locker pulled my bacon out of the fire just a few weeks ago. The 2" lift, 35" Duratracs, and improved shocks are nice too. It really should come with 37s and a skid plate though. Of course its width is not a benefit off-road so I avoid the really narrow trails. That still leaves plenty.

I love Tremors.......but I went the practical route (for me) and went with an 8' box which precludes the Tremor package unfortunately. Oh well, now I have 5453 lbs payload and I wasn't really going to "wheel" my Super Duty anyhow......sure are purty though!

Are you sure that the door sticker says 65 psi on the front? I have a 2016 F350 Dually, diesel, 8' bed, CrewCab, and 4x4 and mine is 75 on the front and 65 on the rear. Those psi numbers will provide enough tire load capacity to insure that you can take the truck all the way to the GVWR of 14,000 lbs...not sure why you would be running 80 in the rear either.

I agree 80 psi on the rears is too much, 65 psi will cover the full GAWR and GVWR.

Thanks ! Can also be had with an XLT, right ? Should be more CCC with less options.
