The G614 sure isn't the standard for comparing a load G tire. Not with its checkered history.
As mentioned we don't see tire issues with foreign made brands in a all steel commercial class G load tires like we do with load C/D/E ST trailer tires.
I see many haulers (commercial) using same 656 Triangles 17.5" on their service trailers with no issues.
If it was me I would run them...but like any tire watch them.
I also wouldn't let them get below 100 psi while sitting for the winter or running 70 mph down the road.
