Well I finally got a answer from Samson about a Load and Inflation chart or table. They do not have one at least the North american office in Canton Ohio does not. They did however confirm that the lowest tire pressure for the GL283A 245/70R19.5 tires, was 80 Lbs with the following. Single tires at 80 PSI = 3865 Lbs Duals at 80 PSI = 3645 Lbs I am running 85 PSI in the fronts and 90 PSI in the real duals of my 2006 Huricane. Way more tire than what is needed. I weighed my Motor home this morning with full Gas propane full Gray and Black Tanks 2/3s full and fresh water 2/3s full Motor home placard is
front axle 7000 Lbs
Rear axle 11000 Lbs
Gvwr 18000 Lbs
My weights on the cat scale were
Front axle 5520 Lbs
Rear axle 10420 Lbs
Total weight 15940 Certified weight.
No handling problems and the ride is smooth
