found images for my old 1980 Silverado trucks wheel info, which has PSI info
Plus have personally replaced a person's half ton pickup wheels when working part time as a tire monkey through collage around 1967-1970's. Still in college and the shop manager/owner took that customers cracked rim to educate me and the customer. That is where I learned about "P" class and "LT" class tires and fit right in with subsequent strength of material classes
Too high a PSI on wheels *WILL* crack the wheel rim...will post back later when time permits and if I can find them on the internet.
To the OP...believe whatever/whomever you wish...it is free world out there
