I'm going to need this one explained to me. This poster went from a tire rated at 2540 lb (at 65 psi) to 2680 lb (at 80 psi). My calculator says less than 6%. Now if it had been the LT235 or LT245, my calculator indicates about 20%. So there must be something else in the tire engineers consideration here . . . and I want to know what it is. This is some more of the information that has not been available to us prior to this thread.
I figured others would not have understood what was going on - hence my post - but I thought you had gotten this: the K factor! The K factor describes the service. So if I take a tire and classify as an ST tire, I use a certain K factor, and If I take the same tire and use it in LT service, there is another (different) K factor that describes that service. All I am doing is equalizing the 2 so we are comparing apples to apples.
OK . . . didn't realize you would do that. I thought you would stick with the numbers on the sidewall.
