I have always found with my vehicles that a few psi above what is placarded gives me the most even tire wear and longest tire life. How much over was a function of the weight of the vehicle, and the quality of the tire - cheaper tires were more sensitive to excessive wear.
A couple of real life examples - in a 2004 Jeep grand Cherokee, I bought the vehicle with 18,000 miles with tires at exactly placarded pressure. The front tires were worn almost smooth on the inside and outside edges, while the center of the tread was hardly worn at all. The rears were in similar condition so tires had been rotated. It would wash out badly in the rain, so the tires were soon replaced and over the next 80,000 I experienced even wear by running them at a higher pressure and rotating every 10,000 miles.
In a 2013 Ford F1 50, the same was also true - much more wear on the inner and outer edges of the front tires. It benefited from higher psi, and also when towing or hauling a load the owners manual recommended Increasing psi for more load carrying ability.
Hi,
Sorry, I thought increasing the pressure would increase centre wear.
Cheers,

It will, but only if you go too high on the pressure.
...... and too high here could mean delta exceeding 20-30 psi , IDK .
