The method of checking and adding air to to tires all ready mounted and installed on the RV is for safety, split rims are rare, I have only seen them on big construction equipment, we would change tires on fire equipment and emergency vehicles, single rim, to seat these tires we had a air tank with a valve in the center and a flat nozzle, place the rim on a small jack so that the lower tire bead rest on the rim hook the air hose to the stem valve no shrader valve, take tank and place at upper opening of tire and rim, quickly open valve on tank there will be a good blast of air that will seat the tire, once seated the shrader valve is installed, tire was moved to a completely enclosed steel cage and finished installing.
The method I described above was taught to the fire crews when checking tire pressure and topping of at the station, some of those tires take 120 psi for the engines and 140 psi for the all steer ladder trucks.
I do not understand fj12ryder's comment of "really?" I prefer to be off to the side of the tire wile checking and topping of than being inches away from having my face remodeled.

The - "check air pressure off to the side" device for use at the fire station (or elsewhere).
Please post a link to same.
Thirty years as a F/F - never saw one.
The ladder truck:
At one time a Truck Company ("hook & ladder") apparatus we had was a Crown Coach quint w/85' Pitman Snorkel.
We had made a right turn from a dead stop at a signal.

*BOOM*!! - left front steel *RIM* failed at a weld in the center of the wheel.
On that particular apparatus, the F/F jump seats are directly over the front wheels.
Definitely got the attention of the guy in that location - as well as everyone else.
Fortunately - the failure took place at about 5mph, no injuries. (still have a pic of the wheel).
BTW - no "hard use" prior to the "event" - just normal driving at
considerably less than the speed limit.
IMO there would have been lots of "believers" for use of a "stand off" device for checking air pressure in the stations - had one been available.
Never heard if there was any exchange of "thoughts" between the fire shop and the (city) tire shop which mounted tires for all the city vehicles...:@
