Quote: "The Commercial Vehicle Safety Alliance is currently exploring how to define underinflation for enforcement purposes. CVSA has already settled on a definition of a "flat" tire: 50% of the max cold inflation pressure stamped on the sidewall of the tire, e.g., 60 psi in a tire stamped for its max load at 120 psi inflation pressure."
That will work until the first ticket is written and the judge is shown that under certain loads with certain tires it's manufacturer approved. If the OEM specs approve the pressure for the load them by definition it's not flat.
Many commercial tires have minimums that are above 50% of the max cold inflation pressure, so for commercial enforcement that would be correct most of the time.
Many LT tires allow pressures at 50% of max cold pressures, or below.
Good article, did you read all of it?
