minimum tire pressure for non towing.

[peaeye1]

This question is on a 2016 F350 superduty Dually. The tires are LT245/75R17E Goodyear,s.Due to the stiff suspension, I would like to reduce the tire pressure to a safe, but more comfortable ride.when not towing. I run 65 rear and 75 front.per Ford's recommendation's when towing.I have looked for a load chart for these tires, but have had no luck.The truck weighs out at 5260 front, and 4280 back.I have a aux tank and carry extra fuel. I will be making a non towing run of about 1300 miles in a few days and would like some info on the minimum PSI I could safely run in these tires on this upcoming trip.

Thanks

The door sticker for my F150 4x4 w/ HD Pkg calls for 55# front and 60# in the rear. I don't change the air when I'm pulling. The OEM tires are LT245/75R17 LRE.

35 pounds in a dually empty will improve ride a lot. On RAM 3500's the tire pressure indicator system does not alarm. Chris

I run 80 front ALL the time, rear 65 loaded at max RAWR and 35 solo rear.

40K on these.

I wouldn't run less than 60 psi on the front tires. Anything less and tire wear seams to dramatically increase from my observations.

The previously provided (and excellent) link above is produced by Toyo. For an equivalent document produced by Goodyear, see:

https://www.goodyeartrucktires.com/pdf/resources/publications/2010_loadinflation.pdf

The load inflation tables have the same values for the size you mentioned, but in case you wanted assurance from the manufacture of your specific brand of tire, you have a resource now from Goodyear.

Inflation tables are standard across the industry for auto and truck tires for any given size. Now with ST trailer tires the rules are all being thrown out the door.

Why so high in the rear, hardly worth the trouble.

I would put the fronts at 65-70 all the time, run 35 in the rear empty and 65 when towing.

No trouble to me.....but then my life is not a hectic as some. I just want to find a PSI for hi speed non towing, interstate running.

6440 pounds of capacity on the rear axle at 35 pounds inflation, or 2 X + what you need. And you are worried????? Chris

I am not worried about weight, just do not want any heat buildup with to little PSI at high speed long runs.Just calm down:R

I run my rear tires the same as the front for non towing, much better ride. 🙂

My old '98 3500 DRW crew cab 4x4 454 weighs 3340 on the rear when empty. Thats just over 800 lbs per tire.
Tires are non OEM LT235/85-16 E so I keep them at 35 psi for a much better ride out here on gravel and chip county roads.

With a diesel, 65 front and 45 rear is quite safe unloaded. Could go as low as 50 front and 35 rear, but that's pushing it, in my opinion.

According to the chart I think I will go with 60 front and 55 rear when not towing.

Thanks to all for the info.
