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.
