To make it as simple as I can…
I am saying based on my reading of the PSA, it says
ST225/75R15 tire with a LR D and carrying a load up to 2270 pounds would have a normal load/PSI of 55, and there fore could be aired to 65PSI the maximum of the wheel to travel at speeds of 66 to 75 MPH…
You can not go above the PSI rating of the wheel… the wheel is the tire and rim assembly… for example my rims are rated for 75PSI and my tire is rated for 65 PSI, making my wheel rating 65PSI, the lower of the two…
Your answer is 2. Was that so hard?
Could you please then cite the phrasing of the PSB that actually says what you believe like I did?
Sorry if I am being thick on this, but I CAN read.
Where, exactly, did I misread?
