ERS said "The problem I see though is that because there is a difference in the way they calculate those max load numbers for LT and ST tires, there may be situations where switching to an LT tire from the ST tire may actually be a step up, but it is not obvious by reading the numbers on the sidewall because they are calculated differently. This is where I am begging and pleading to the experts like you and CapriRacer who know how to do this correctly. "
I don't understand why you believe that because the formulas used to calculate ST loads are slightly different than the formulas used to calculate LT loads means the answers are wrong.
Lets try this. Can you confirm that there is only one formula used to calculate the drag force and aerodynamic lift on a Cesna 182, an F-8 Bearcat, an F18 and the B2? If there is more than one formula then obviously one or more of these aircraft cannot fly.
I thought there was one formula that contained a variable K that differed between the two and would thus give different answers, all other things being equal. Is that wrong?
