The tire is rated for both speed and maxiumum weight carrying ability and that pressure (cold) is on the side of every tire. It does not matter if its on a 5k Toyota or a 6k Ford. That speed and weight capability will not change. Some tire manufacturers publish specs for their tires that show speed and weight ratings at various tire pressures. I’ve not found that info (yet) for the KO2. From my experience you can also generate too much heat in a tire when you make it work at a pressure below a certain point. While Ford builds a fine truck, maybe they’re not so good at tire management - maybe they’re better now - who knows. https://en.m.wikipedia.org/wiki/Firestone_and_Ford_tire_controversy#Ford_Explorer
Yes, maximum, not optimum or recommended for a vehicle. I will agree to disagree. And from the sounds of it most use the auto manufacturers pressure. I'm not interested in doing research to try and prove one of us wrong. For 31 plus years I have used auto manufacturer pressure with no failures or uneven tread wear.
I agree with the above. Vehicle’s recommended pressure. Not the maximum tire capacity. Thought everyone knows this
