I run 80 psi all tires all the time. The reason being it's easier and more time to spot a tire going flat.

I have driven many miles. Lower starting pressures builds more heat. It actually inflates the tire the longer driving. Too much heat causes blowouts.


This only applies if the tire is overloaded and under pressured. If the lower pressure is adequate for the amount of weight on the tire then there's no problem.

I too have a 3500 SRW Ram/Cummins and run 55-60 front year around and 75 loaded/towing and 50 non loaded on the rear. At 50 on the rear according to my TPMS even in the hottest of days here in Georgia the highest heated pressure I've ever seen is maybe 55-56 and no excessive heat on the tire

"The door post says 50 psi front and 80 psi rear "

That's insane!!! My 98 4x4 with 3rd gen tires and wheels I ran 72 front 35-40 rear unloaded. I would get 100k BFG's and 120K Michelins.

PROPER inflation is EVERYTHING!!!

Blindly running at full inflation can give rough ride, longer stopping distance and poor tire wear. Weight/inflation tables are there for a reason!!!

I think your right. But logistically I'm not inflating /deflating tires after every trip. I can't imagine everyone else goes through an air up air down ritual each trip[emoticon]

Some do but I can’t be bothered. Mine are inflated to door sticker pressures for summer towing season. Up north the tt gets put away from oct to May so it makes sense to lower them for that period.

All of my vehicle tires are aired up to the max = Mini Van, K3500 Suburban and Frontier crew

Performance is on my have to have list and ride quality isn't....ride quality is at the bottom of my nice to have list

All personal choice topic and how/where/etc you drive...there isn't a one size fits all on this topic...as it is with most topics...

Also remind folks of what Ford did solely for ride quality (not for performance) on the Explorer and the subsequent federally mandated dash & tire PSI monitor/warning lite...have to maim/kill folks before it sinks in...

When I travel south I am at my towing pressures If I am at a site for only a few days I leave the pressures high. If I am there for a couple weeks or longer they get dropped.

I hope you never have to make a emergency stop in a low traction situation with a pickup with with 80 PSI with no load in the bed.

In talking with Michelin about inflation a couple of times they stated that beside low traction issues, and over inflated tire for the load in more likely to receive impact damage when over inflated for the load.

I do know having owned my 2001 RAM 2500 std cab lb for 14 years that with 80 psi in the rear empty it handle a bit squirrely.

But to each their own. And please do not tailgate me if you are ever behind me.

I agree with you. It depends on what your primary "performance" trait you are trying to maximize. Because everything is a compromise. Ben's definition of performance is load capacity. Where others may be traction, ride quality, tread life or some combination thereof. There is never any one perfect answer when dealing with multiple mutually exclusive (to some degree) options.

The way I see it this is a towing forum. Max. pressure is generally what's needed for towing. Towing is what we all have in common.
Once we stray away from towing and the discussion turns to groceries,driving across a sandy beach low traction or doing anything else our needs and perspectives will change drastically.
