F350 rear tire pressure
Are you f350 owners always running your rears at 80psi? Or do you lower when not towing n 80 when towing
|
I run mine at 80 consistently. It doesn't ride any worse than my 2010 F150. 2018 CCLB F350.
|
I drop mine. 65psi seems to smooth out the ride for me.

I suppose it depends on how much of your driving is while towing. 80% of my driving is towing, so I leave them at 80 PSI.

When u do 65 in rear it doesn't set off the low pressure sensor?
I plan to put set my low pressure trip point to 55 PSI - You'd be amazed how the ride improves as you drop PSI. For more info on forscan see here: Forscan |
I have our truck’s cold tire pressures lowered from 65F/80R to 55F/65R psi when lightly loaded; the ride is less jittery. No FORscan adjustment, no TPMS issue. However, I suspect I’m flirting with triggering a TPMS warning. HTH, Jim / crewzer |
I run mine at 55 all the way around unless I’m towing heavy. Rides way better & tire wear is even across the tread on all 4. Used Forscan to drop TPMS to 45. |
I keep mine at 80 because the way my work goes I never know when I might have to hook up and deliver a load. Boy Scout motto: Be prepared.

Im running 60 all around. I used FORscan and set them at 55. i also noticed that FordPass also adjusts recommended pressure to whatever FORscan changed it too.

I drop my F350 CCLB from the standard 65/80 to 65/75 in the summer (towing season) and to 60/65 when the snow starts to fly and I know I will not be towing. I have lowered my TPMS to 55 with forescan.

55 empty rear

I have a dually, but what I am going to describe applies to SRW or DRW.
To maximize tire life, the best thing to do is to adjust pressure based on weight on that axle. There are load inflation tables from all tire manufactures. I have weighed my truck, both loaded and unloaded. I then use my axle weight and the load inflation table and adjust my tire pressures accordingly. For my front, loaded or unloaded, I run my tires at 65psi. For the rears, loaded, I run my pressure at 57psi. For the rears, unloaded, I run my pressure at 34psi. I got 74k miles out of my last set of rears on my 2012. |

Remaining tread depth was 3mm which is above the legal limit, but too shallow for winter driving in my opinion. |
