This exact jack would not get under a flat tire on my trailer, at least not under the spring perch. I carry a small floor jack with a 1x6 if needed.
Do you also carry the important part needed to safely use that jack? By that I mean a floor.
With no load on it, run the jack up. Notice the lift pad goes up in a arc? Normal lifting, the pad stays in contact with lifting point be cause the jack rolls under the load. If the wheels are setting on soft or rough surface the pad must slide on you lift point. At least you're not under when it drops.
Thin board UNDER the floor or trolley jack just like you SHOULD use under ANY jack solves your objection.
Was taught many yrs ago to never use any jack directly on ground as that ground can give way unevenly resulting in the jack tipping over.
Something else to consider, with a floor or trolley jack, the arc is small, maybe 1/4" inch in total travel for the entire lift. The vehicle also moves with that arc, your assuming the vehicle stays put and never moves which is not true. Trailers and vehicles are on wheels, the brakes, drive line have slop in them which allows the vehicle to move back and forth.
