I have 8 ply tires on the truck. I was able to get home with several holes in the sidewalls. 5+ hour drive, but it worked. LOL, The BFG KO 2's in load range E are pretty tuff. The trailer tires wouldn't have made it 30 minutes.
I replaced them with KO3's which are just the latest version. They look beefier but they don't seem to rde as well.
