To satisfy my own curiosity, I contacted DexStar directly. I received an email which I will copy and paste here when I'm able to get onto my computer. It's too much of a pain in the neck to do it from my shoe phone.
Basically I was told explicitly not to use those wheels on any vehicle (see below). They are not rated at all for use on any vehicle, including antique trucks. I was also told that they will be contacting e-trailer with the same warning.

Good Morning, Thank you for bringing this to our attention, we will contact Etrailer accordingly, as the Dexstar steel Conventional style wheels are NOT rated for automotive use and such use would void any warranty.
Please do NOT use any wheels rated for Trailer Use Only, as stamped on our wheels, on your automobiles. We have had a lot of similar inquiries when it comes to older trucks as well, also not rated or tested to be used, even on old 57 Fords.
Thank you for reaching out!!
