Scales can be sought after at, Moving-Van and storage facilities, Refuse disposal facilities, truck scales and more.


Just get the coach weighed. Get the front axle, the rear axle and, the total weight. THEN, go the tire pressure chart of the maker of YOUR tires and, be guided by what they print. The coach builders put specs on there based on certain guide lines but, are not specific to ACTUAL loading of your particular coach. Those specs are within reason to operated it safely. But, for the best ride, the best tire mileage, the best handling and more, go by the specs of the tire chart, AFTER COMPLETE LOADING.
Oh, by the way, do it with a full WATER TANK too.
I agree that "for the best ride, the best tire mileage, the best handling and more, go by the specs of the tire chart, AFTER COMPLETE LOADING".

HOWEVER, if I HAD relied on only the front and rear axle weights of my coach, (and NOT "worried about the four corner weigh measurement")... all 3 of my left side tires would be UNDER-INFLATED.

The ONLY way to determine the proper tire pressures necessary for the tires on a particular MH is to individually weigh the fully loaded coach AT ALL FOUR CORNERS.

Holy Cow,
I don't want to think that hard . It seems, most of the tires are thrown away, with little use, in seven years anyway.

Goodyear RV, Michelin, Toyo, Firestone, Bridgestone all use the (S) and (D) notation on their tire inflation charts for RV-size tires.
Yes, but that's not the point that Pusherman raised. Michelin now specifies the (D) value as a combined rating for two tires, while the others show the (D) rating for a single tire. It's crucial to know whether the value shown in the table is for one tire or two.
