It’s not that wild - I run 40-45 PSI in all my tires, including BFG’s, and get 60k miles out of them because they wear slowly and evenly.
The pictures of tires worn on the edges (underinflation) and centers (overinflation) are examples of EXTREME cases of each. Tire shops love to display these.
But they won’t tell you that in order to produce those exaggerated examples, you need about 20 PSI under or over the recommended pressures, not just 10.
You are free to follow your door jamb sticker from the factory (generally lower) or your tire company’s info (generally higher) but I have run each set of tires in all of the vehicles I’ve owed, collectively at least 10 sets, and have ALWAYS exceeded the mileage rated by 10-20k miles before the tread depth indicated replacement was due.
I’ve never let a set run bald just to squeeze more mileage out of them. This is legal mileage I’ve achieved with an SUV’s weight, 4500-5500 pounds, spread over four 40-45 PSI tires.
You WILL notice a rolling resistance difference between 35 PSI and 45 PSI, but your tires with wear deceptively evenly under both. 45 PSI they just last a little longer.
