Tire Pressure for Karl December 06, 2012, 04:36:06 pm Yahoo Message Number: 135581Karl, Chris and others; With a GVWR of 10,500, Karl may have load range 'D' tires, not the load range 'E' tires that are on the newer and heavier LD's today. The load range 'D' tires would have a lower maximum pressures. One other thing is that your propane capacity is probably only 8 gallons in a 10 gallon tank, unless you have a 12 gallon tank. Hope this helped. RonB and 'Bluebelle'[Non-text portions of this message have been removed]
