Recently I installed a set of Vision aftermarket wheels with Cooper Discoverer ATP II on my 2019 LT Silverado. 17 x 8.5 wheel, LT265/70/17 Tire. 

Discount Tire Direct has these recommended at 43 psi cold. seems a bit light for an E load tire. I know the tire will ride harsher bc of its carrying capacity design. I do tow occasionally and more in the summer months. My thoughts are about working the sidewalls to much with to little air if this is not correct. I do notice they increase to 47-48 once running for my 1.5 hour commute to work...

any thought are appreciated!.

I ran mine at 40psi unless I was towing/hauling heavy then moved them up to 60psi.  Just keep an eye on the wear.  No worries running at 40psi for sidewall issues.  Mine lasted 75K miles.

I don't have the same edition silverado as you but my 14 I keep the BFG All-terrains inflated to 45psi cold and after thruway driving it goes up to 49-50psi in the front and stays at 47-48 psi in the rear. My tires are worn perfectly even on the front and rear and across the whole tire. I do rotate my tires from side to side and front to back twice a year though but they still are totally flat for wear.

You need enough air to exceed your axle capacities.  43 psi puts a pair of tires at 4366 pounds.  I initially ran mine at 49 psi and after 40K miles, they were wore down 1/32 more in the center.  42 was perfect for mine.

I'm at 40 rear 42 front, I've got nothing in the bed and not towing anything, any pressure less I was getting a shake, had them balanced 4 times, never a change, once I went up over 40 PSI it ride smooth as can be & perfect wear for the almost 20k I've put on them so far. very happy.

Thank you all for sharing your set up. I`ve up`d the psi to 44 with ambient temps @ 43 degrees. Yesterday the fronts got up to 50-51, and the rears 47-48. Today was much colder and the psi lower. But cold pressure at 44 is very smooth, handles very well, except for the mushy front stock shocks. I`ll keep an eye on the wear and adjust from there.

Thank you all!!!

Not to overcomplicate this, But as long as you do not run below 41ish PSI you will not drop below factory weight carrying ability at any point. if you decide to go up, then that is your choice. I found my sweet spot at about 45psi.

what are your pressures once the tires are heated up for a while?

Don’t know if it’s true or not, but I once heard that  good rule of thumb is if your cold pressure jumps over 10% once their warm while driving, then you need to add more. So if you have 40psi cold then while driving it gets up to 45+ then you might try adding a little more. Like I said, don’t know how accurate this is, it’s just what I’ve read somewhere on some forum.

On Nitrogen I'd see about 2psi swing cold to hot.

Regular air will be slightly higher fluctuation like 4ish psi, but that is normal operation.

      2027 GMC Sierra: Official Discussion

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
