Es call for max 110 psi, trailer sticker calls for 80 psi. Would the extra pressure not cause center tread wear due to over inflation for the load? And a firmer ride?
Never mind, headed over to this thread, http://www.keystoneforums.com/forums...play.php?f=135 |
Inflating tires supporting RV trailer axle/tire loads to an inflation pressure to “carry the load” is not an acceptable or approved inflation pressure method for that application. It’s a method use by the commercial trucking industry and their regulations which are found in the Federal Motor Carrier Safety Administration regulations.
Federal regulations and tire industry standards fully support the trailer manufacturer’s recommendations for Original Equipment tires and their replacements.
When considering deviating from the normal methods you must consider the drawbacks. RV trailers are notorious for having overloaded wheel positions. Inflating their tires to the load carried requires each wheel position to be weighed. Then determine the inflation pressure needed to support the heaviest position and inflate all tires to that PSI value. Federal regulations require all tires on the same axle to be inflated to the same PSI. When inflating to the load carried and the load on the heaviest position will require tire inflation that exceeds the tires maximum allowed inflation pressure, you’re going to have to get some weight off that tire position. Inflating tires to the load carried does not provide any load capacity reserves. Older tires may have degraded to the point of needing the load capacity reserves necessary to safely carry the load. There are more obstacles; I’m just going to stop there.
