overweight -1st Press release
The 315s have a higher per-tire weight capacity than the 12R22.5s I run. That would account for the difference. If I were to convert to 315, I could probably lower my pressure. (There are some concerns about clearance between the duals when converting from 12Rs to 315s.)
The data plate is "legally binding" so a verbal assurance from Bennie has no real impact. If you were to have an accident due to "overloading" then BB would have no legal responsibility since the manufacturer's plate has a lower weight rating. I note, however, that the sum of the axle ratings on my coach total (something like) 52,000 lbs -- but the official GVWR is 48,900 lbs. The difference is based on the manufacturer's evaluation of the system as a whole. In reality, the axle and suspension system has a pretty decent safety factor beyond the rated weights. It's unlikely that a weight related failure would occur to the axles or air bags unless the loading was perhaps 30 or 50% above the rated value. Tires are the one major component that you have to "believe" the manufacturer's limits -- and the one death that occurred in a 2007 (as I recall -- I met the owners a few weeks before his accident at a SWBB rally in Buelton, CA) was due to a front axle tire blowing out, followed by an excursion from the highway ending in contact with a tree. The driver died shortly after the collision, his wife, in the bathroom at the time, was not seriously injured. Her not being in the passenger seat may have saved her life. From what I've read about the 'recall' coaches -- with suggested 130* psi for the front tires post-recall -- indicates that the tires are very near their maximum load rating and are therefore the 'weak link' in the equation. *Most heavy duty tires have a 120 psi maximum -- as do the Alcoa wheels on my coach (according to the data stamped into the wheel).
