Dodge Ram in sig

(How High?): According to the scaled load.

Each tire is at 1,985-lbs.
(7,940-lbs)
Tire maximum load is 3,000-lbs

The Load & Pressure Table (Michelin)
shows 45-psi meets equalization

Dodge wants not less than
50-psi

Maximum is 80-psi. That’s only seen when I hitch my 35’ travel trailer and am at that limit on the Drive Axle. The front moves to 55-psi.

— Overinflation ruins the ride
— Subjects the tire to more damage
— Worsens braking
— And, where FF/RR bias is ignored,
worsens handling.

My tire life average is well above 100k per set, to
the point that (2) sets covered the first
quarter-million miles.

The penalties offset the minor gains.

— Tire DESIGN is the critical factor. The right tire for intended use.

From seeing lots of medium duty trucks at my past tire shop jobs, I would say 50 PSI is perfectly reasonable in the rear. Many trucks wore out the center of the rear tires first, as i'm assuming they ran 80 PSI or close to it. Plus this is Georgia, where pickup trucks are used as fashion accessories more often than actual tools. Very little load most of the time.

The front tires on the other hand tended to wear the edges with 55 PSI specified, maybe 60 would be a more reasonable pressure? Of course, your truck, your experience. If you are getting even wear and 100K+ miles from each set of tires, I think whatever you are doing is working, and you should keep doing it!

Does driving through soup give it good flavor? Does adding a dime to the soup, really change the flavor?

Driving through soup leaves a bad taste in my mouth, and you'll never notice a dime under tires that are under 40 psi.

I'll have to inflate over 40PSI, so I can feel as one (dime?) with the road.

My new Ecopias spec a max of 44psi, so that's what I run. This is 3 bars on my gauge.

My Ecopias have a max sidewall of 44 PSI as well. Doesn't stop me from running 47 rear, 51 front!

I'm sure there's a lot of cushion when manufacturers stipulate a sidewall PSI. In fact, the sidewall PSI spec is usually stated in terms that say or imply that the PSI level is what it takes in order to carry the maximum weight the tire can carry. So, it's not necessarily all the PSI the tire can take; it's just that it takes the specified PSI to handle the rated maximum weight.

As noted, my Ecopias specify 44 PSI too, so that's my target pressure.

My previous tires were Yokohamas which specified 51 PSI on the sidewalls. I usually ran at or about that level, but one of them developed a tread separation. I wondered if the 51 PSI was helpful or harmful in regards to the failure. I doubt that it was related to the failure, but there is no way to tell for sure.

A more likely factor causing the tread separation was the three "flats" and related repairs that poor tire had suffered through the years before it finally succumbed. Not helping was the fact that two of the flat-causing nails were within an inch of each other. Those malicious assaults on the tire were probably the real reason for the tread separation that killed my poor ole YOKO, and not the high 51 PSI.
