Ok well you tow also which is why you run higher pressures. When I call nitto and tell them exactly what I use the truck for and they recommend 45psi, I’m going to listen to the manufacturer. They also stated anytime I tow to bump to the max, but to come down for normal city and highway driving.I have run my tires at max pressure for over 30 years. Don’t listen to the kids at Discount tire regurgitating information from a training handbook. I have circled the US in many types of vehicles in every weather condition and my job sites are often war zones and mud holes for topography. Never been stuck, my vehicles handle with precise response and my tread always wears even. I always get the 80psi???are you sure??? As an engineer major products are under engineered and the given spec on a product is given with max tolerances in mind for regular use unless noted otherwise. Your vehicle handles as it should at max psi for the given tire. Running an under inflated tire is dangerous at high speeds not allowing quick crisp maneuvering...there is roll in the tire and this is not only unsafe at high speed curves on mountains but actually will damage your tire and cause uneven wear.
At max tire pressure, less of the tire is touching the surface creating bounce. More bounce = less handling ability especially at highway speeds.Photos are wheel gaps front to bacView attachment 30744 View attachment 30745 View attachment 30746 View attachment 30747 View attachment 30748

Jesus what a nerd, you can tell your tire pressure within 2-3 psi, yeah ok. Sounds like you’re full of yourself! If you’re at 80psi and on the highway for more than 50 miles I guarantee you’re running those tires over 80, but hey, you do you, keep your fingers crossed you dont have a blowout one day and injure yourself or god forbid someone else. I’ll be on the lookout for you during my travels and be sure to drive the other wayYou obviously have no real world experience in testing your false statements. Set your tires at 50% max pressure and maneuver through big city highway traffic and check your lateral roll, run through 10 tanks of gas and compute your gas mileage, run them through 40,000 miles and gauge their wear across the tread,. Then repeat at 90-100%psi. I have personally done these comparisons several times with different vehicles and different tires from performance to A/T. The handling and response is night and day. My ride doesn’t bounce even a minuscule. Lateral response is higher. Gas mileage is higher. Turning is lighter. An under inflated tire generates more heat and wears uneven. If you have a tire that wears uneven by running it at its max psi no matter the condition...it’s poorly made and you should stop buying 99$ tires. I have 30k miles on this set and can show with a gauge my wear is even across with just a slight more (.5mm) near edge due to aggressive driving.
I don’t run my tires over 80 and under some conditions drop them to 75. When I head out on a trip I adjust tires as needed at each stop to maintain proper pressure. I have over 1million miles under my belt and I can tell what my pressure is in each tire within 2-3 psi just by driving. Many moons ago I worked for an OTR company in Chicago maintaining the tractors and trailers tires and brakes. Most tire failures are not due to over inflation. Mostly it’s due to an etiolated, worn or poorly manufactured tire. A manufacturer has recommended psi rating based upon the load on the tire. The pressure goes up to match the load which actually increases the force on the inside of the material, valve stem and bead...there is now a greater risk for failure. Therefore running at higher psi without load will decrease failure point while increasing tire stiffness. Basic physics. I like a stiff handling tire. If I drove a 1 ton pickup as a grocery getter or work commuter as most do, I would probably adjust, but I don’t and never willl. One ton passenger vans ride very nice at max psi with Bilsteins. I’ve had 3.
I know everything your regurgitating and most likely quite a bit more. A tire is in no way in danger of exploding at stated max psi...that’s laughable. When any product is engineered it’s given operating specs far below its actual fail points...otherwise products across the board would fail constantly. A cheap, old, or stressed tire may fail due to exponential decay of materials. A quality manufactured passenger tire with a max psi of 65psi will easily handle 150psi before failure. You can watch YouTube videos proving this on old worn tires.
So you go ahead with and do you and enjoy your floppy ass boat ride down the freeway. I love out maneuvering guys like you in and out of lanes. It really comes down to ride preference and real world application. Never a blow out or stuck in my life from desert to blizzards. I live in both. Hauled my trailer over and over through deep snow on Colorado passes at full psi passing underinflated passenger cars and trucks like butter. Never hydroplaned in torrential downpours across the nation. Real world experience beats any manual young man. Manuals are basic guidelines for the masses...a one shoe fits most to keep the stupid safe and the ignorant pointed.
