Those plaques the RV manufactures put on vehicles spelling out tire pressures are absolutely dangerous. But I think they are required by the feds.
With not a clue in the world of what tires you are running on your rig how could they possibly be able to tell you what air pressures to run with.
How many rigs are out there right now running down the road with severely under inflated tires because somebody use those stupid plaque recommendations?
Perhaps a little work with a hammer and chisel might save some lives.
I call BS on these statements.
I suggest you retract them as what you are saying is incorrect, misleading and potentially dangerous!
The tire placard pressures stated by the Manufacturer are those required for the tires to run with axle loads at their maximum. Tires at the pressures on that placard are NOT "severely underinflated" unless the vehicle is also overloaded. You are right in that "they are required by the Feds". The Feds also require that the pressures are as I have stated.
Turning your statement around, the tire manufacturers have no idea what weight the tires will be carrying, so how can they know what pressure you should run?
(They provide load/inflation charts for that purpose. The numbers on the tire label will be very close to those chart numbers for the weight being carried)
(In the interests of full disclosure, those labels used to be part of my job at one of the "Big 3" so I do know what I am talking about!)
