Every major light truck tire manufacturer that I’ve researched disallow replacing original equipment special trailer tires with their light truck tires. Don’t take my word for it, do some researching. When reading tire warranties look at the heading “what is not covered”. The key word is “misapplication”.
More and more tire retailers are just not going to take on the responsibility of what is considered a misapplication.
Of course, tires approved and touted as trailer tires by their manufacturers are suitable to replace ST tires. The Goodyear G614, Kumho 857 or Hankook RA08 are a few of them.
