Tire air pressure

So I have been thinking about this allot. What does everyone run for air pressure in there truck tires. Do you follow what is on the door of the truck. Or do you follow what is said on the tire, witch is allot more then what is on the door. They said the door pressure is for best ride. Then I heard you should follow what's on the tire for better wear on the tires. So what does everyone do. I have done what's on the door but I seem to burn up tires.

80 rear, 65 front per the door sticker. I could let a little our the rear when not towing to smooth out the ride but it is to much trouble for me.

The max pressure on the sidewall is for running at max load capacity. If you are well under that you will be happier with 60 or so psi. I ran 50 psi in winter and 60 psi in my load range E tires on my old Ram 2500. In my current Tundra the door says 30/F and 33/R while the max sidewall is 44#. I run at 40# during the summer to stiffen to tires up a little.

I have Load Range E Firestone Transforce tires on the TV, and run fronts at 70, rears at 80, all the time. Tried letting a little out of rears when not towing, and saw no difference in ride. Ride is always smooth and comfortable, towing or not. Wear is very slow at these pressures.

Towing/loaded 80 front, 80 rear (heavy setting)
unloaded 65 front, 50 rear (light setting)

my factory TPMS has two settings, heavy and light, this combo meets the criteria for the TPMS settings.

Light load the ride is much softer, however during the summer when towing a lot, I usually will leave the tires at the heavy setting, and I actually get used to the rougher ride

My TV door states 80psi rear and 55psi front. My tires say max air pressure is 80. So, I run with 55psi all around when not towing but ramp up the rear tires to 80 when towing. I tried keeping 80psi in the rear tires all the time but the ride was too rough.

I also run #40 rear in my Tundra and #32 front. In summer if on longer haul I will go to #44 in the rear.

Tire air pressure

I have an 07 Sequoia...running 35 in both tires based on the door sticker (which actually says 33). Am I doing something wrong? Should I be using much more pressure?

Truck in signature and I've found best ride, mileage, and wear happen for me at 70-72 psi front and rear. I'm loaded 50% of the time.

I keep them close to the sidewall max all the time. In the winter I want it to cut through the snow, so I don't want any sidewall squashing. I also tow a large snowmobile trailer as often as possible. In the summer, we're camping as often as possible. It's just not worth the effort to be changing it all the time, and I don't like the spongy ride caused by the lower pressure.

Nothing wrong with that. You may jump to 40 - 44 psi to stiffen up the sidewalls some and take a little of the squishy feel out. It's trial and error sometimes.

So you guys think you get better tire wear at the higher pressure on the sidewall of tire

The best way to check contact pattern is to park in a paved lot or driveway, take sidewalk chalk and draw a straight line across the tire from shoulder to shoulder. Then drive until the lines are transferred to the pavement and see what it looks like. Adjust pressure accordingly.
