That article has to be wrong, sometimes I just don't know who writes these things, what about all the times cars are on lifts for repairs, what about spare tires, etc, etc, sounds crazy to me..
Tires are not in the least damaged by being off the ground... At least not the tire that is off the ground.
What they are refering to is this: IF you level, as I do, using blocks, then all tires need to be supported or the tire on the blocks will be carrying double it's load and that can cause damage.
I have also read about folks who claim that if you lift a tire off the ground it will somehow damage the suspension.
Suspension designed to hold up thousands of pounds of motor home is going to be damaged by holding up a couiple hundred pounds of tire rim and axle/brake... I don't think so.
The major danger (And this DOES not apply to tag axles at all) is this... If you lift all your front or rear wheels off the ground the rig can move sideways, Or if you lift just one rear wheel forward and backward, And jacks are about a kilobuck a pop installed.
Now.. as for the "Share the load" If you are leveling with jacks, then when the tag comes off the ground the remaining wheels are carrying very little load.. The jacks hold the rest.
