I run 65 lbs in the front and 70 in the rear all the time. 265/75/16 E tires. Works for me.

I do the same year round. My first set of tires gave me 68,000, my current set is at 58,000 miles. I don't think I will get as many miles this time as the originals.

On your next set try 72 front and 45 rear solo and increase the rears to the proper psi for the load when towing. I easily get 100-120K at those pressures with Michelins or BFG's.

I will give it a try. I ran BF the first time and Michelin this time.

Thanks.

Yes I am talking about the rear wheels, pulling a 5th wheel.

Ok, so some of you DO adjust the air pressure... For those who do adjust, how do you increase the pressure? Do you use a portable air compressor hooked up to the cigarette 12V power?

When we eventually go full-timing, we will drive a 1t dually. Will dually behave ok not towing when the tires are max pressured? We do expect to drive every day and sometimes 100-200 miles at a time when not towing.

My rears are at 80 PSI 100% of the time, no adjusting.

Most of you are perfect examples of why you never see more than 50-60K on a set of tires. Too much air for the actual load on the rear loaded or solo. Too little air on the front.

But if you want to blindly go by what the mfg says that tries to cover all scenarios by all means do so.

Tires on my 5er stay at 80 PSI (max psi) all year long.

My truck stays at the "loaded" recommendation from April - September. Off season I go to light load.

X2 Too much work adjusting pressures all year. We have better things to do.

Huh? Am I missing something?

OH, yes, I lower the pressure to 60lbs if I am staying more than a week. I have an on board air compressor.

My door sticker shows 75 ft, and 80r. I looked in manual, it says to run tire pressure at door sticker. It goes further to say, "do not lower below door sticker pressure to get a softer ride", and says door pressure is for best handling and safe use of vehicle.

My General tire booklet, that came in manual pack, for my General Grabber tires, says to go by vehicle manufacturers recommended pressure.

I have to say, it does handle best, at that pressure when unloaded. I don't have to change when loaded with pin wt, as the rear is at max 80. The tires show no center wear.

My Ford manual for a DRW truck says 65 psi rear and nothing about changing for loads, towing, etc, so I just leave it as is all the time.

my 2012 Ford DRW says max load (RAWR at 9000) is at 60psi. but I find I get better behavior at 80psi.

I was thinking go to max (80psi) when loaded and towing. Leave it alone while out on the trip. When you get home, drop front and rear to the door sticker mfg recommended. Full timers would have some hybrid of this.
