I have seen 84-88 trucks/pickups with these rims in the EU market, but I can not tell if they are Toyota OEM rims.

 

I do not think they are OEM
At least from the angle of the pictures, the offset does not look right.
Do you actually have one on hand that you might examine its' markings??

 

Thank you for your answer, millball.
I have a complete set, but I do not see any marking, brand or inscriptions.
Those rims are very common in the EU market 84-88 trucks/pickups, to the point I thought they were OEM.

 

Strange
Just about every rim has some sort of markings somewhere.
Most made for sale in U.S. have a DOT ID
