This of course still being in the time of “balloon” vs. solid tires. Stabilized appears to be referring to something about the tread construction, but reads almost as if it has rubber (therefore, much stiffer)
plies, as opposed to just a cloth sock like was typical back then.

You are correct . Title edited.

I wasn’t trying to be pedantic, I was just making an ( editor’s note: they used to call pneumatic tires balloon tires) kind of thing for anybody who might be confused.
The ply thing (possibly using a weave of rubber cord instead of the soon-to-come nylon?) and the advertised thicker profile cast rubber tread being square section (!) are the points of interest here - this is probably in a lot of ways an immediate forerunner to the “pie crust” style bias plies that dominated for years.
It’s also likely one of the earliest modern -well, sort of modern - style whitewalls.

Notice also that it lists regarding the tubes that red tubes are of “purest antimony”. Apparently antimony sulfide
and antimony oxide are vulcanizing agents and responsible for the red color found in red gasket rubber and the like. Somehow I had not known they used that to make tubes with until better formulations came along.

“I wasn’t trying to be pedantic.” I think I know you well enough by now, you just want answers! :-)x
I’m not sure it’s the tire at all. Sounds like something working with the tube to push the tire onto the wheel tight where it would normally slip or move off center. Dayton Stabilized Balloons to be used with Dayton Tubes and Dayton Thorobred Cords low pressure tires . I think.

Just went to the shelf and pulled the oldest issue (1926). The second car related ad I found:

I think in the first ad, referring to the “balloon” in companionship to the normal “cord” is a question of section size. In other words, referring to a cord-style tire vs. balloon, the balloon would be large section, fitting a different wheel.
This is borne out by the ad describing the “balloon” including info on the construction and tread that wouldn’t apply to a tire add-on.
In the second ad, the other car may have pneumatic tires, but of smaller section. Clearly “balloon” evolved into a term of art other than the original turn of the century meaning of just pneumatic.
I’m guessing what held back early attempts to build a “stable” “balloon” i.e. large section was the tendency to skew - since obviously without strong plies the tire can’t be inflated enough to resist buckling, even disregarding the floppiness of rubberized cloth sidewalls.
Reinforcing the sidewalls and section profile therefore does two things for you. It may be something else and really weird here, though, like laying rubber cords much like radial cords but into the inside of the carcass.
Who knows what got tried before modern chemistry?

Edit: second ad is probably solids because of how square they are. Missed on first pass. Regardless, pneumatic tires with a small profile like that were still the norm.
