4 Corner weigh, Washington State

Roger and Mary, I still don’t understand the statement, “since rear weights are the same no need to do the calculation”.
Are you saying that it is not possible to have more weight on one side than the other?

Just for the record, NASA 'orbiter' did a face plant into Mars. The list of epic NASA failures would lead lone to question if you want them inflating your tires.

I got new tires on my last rig and had the truck tire center inflate the tires to the 'correct' pressure. A short later I had some work done at the big RV center. When I checked the tires they had lowered the rear tire pressure to 80 psig.

So yes you can match the weight of the load with the carrying capacity of the tires by reducing the safety margin. Good luck.

Not sure what NASA has to do with inflating tires on a motorhome. Also not sure why anyone would let any tire store determine what pressure to inflate your tires to. My method is to know what each position weighs and I determine what pressure to use referencing the load inflation tables. As long as they are inflated to the minimum recommended pressure for the load I'm good to go. The tire engineers have determined the safe pressures. Adding more does not make them any safer, but just eliminates the need to add air when the morning OAT is lower. Extra pressure also causes uneven tire wear. Ask me how I know. My method has worked well over the last three coaches and 150,000 miles traveled without any tire problems. I plan to continue the same.

I've done a 4 corner and axle weights. The 4 corner after an axle weight was not necessary. Wasted $40.

Your four corner weights proved that your coach is well balanced, so it wasn't a wasted $40. Others including myself found one or more positions were heavier than what the tire was rated for, thus avoiding a premature failure. A 4 corner weigh is well worth the cost if not for peace of mind, to correct a problem.
