Like I've told you before, you shouldn't refer to the site cnx.org to understand how forces are acting on a tire. You have all the info and tools you need to do the job you have to do on your vehicle. From my point of view, you are complicating stuff more than it needs to be. Just start by doing the simple calculations as proposed on HPWizard.com and things should come clearer as you go on.
