I don’t see the “grenade” in your comment. I think you’re correct as long as you don’t mind buying tires more often than necessary. Physics will tell you that there’s a relationship between the load on the tire and inflation. I believe that is what the Goodyear chart of tire pressure vs weight does. Goodyear has done the work for you and probably more accurately than any of can do on our own. But nothing is preventing anyone from determining this empirically for themselves.
Having said that, it’s up to each person to inflate the tires on their trailer as they see fit. I don’t see a safety issue with over-inflating tires, so long as you don’t exceed the maximum and you check the tread wear regularly. If you do those things, the worst that should happen is you wear the center treads out prematurely…like the guy that owned my trailer before me.
My comments and observations are offered only to explain what I am doing and the logic I used to make my decision. If anyone thinks I’m wrong they are free to both ignore my advice and if they’re inclined, point out the fault(s) in my logic. However, saying Grand Design cites Goodyear’s max inflation as a counter argument misses the point that max inflation isn’t necessarily the correct inflation; hence, the Goodyear chart.
I cannot remember the last time anyone posted about needing trailer tires because the tread was worn out. They almost always age out or blowout long before the tread is gone.
And it is true that in the case of a blowout on a 2 axle trailer, that the remaing tire on that side is instantly overloaded... So max inflation may save you from having to buy 2 tires in the event you have a blowout. A quality tire will not wear out the center of the tread from over inflation....But most ST tires are not quality.
