The average consumer seeking replacement tires have no real reason to cross over to something different than what has been recommended by the vehicle manufacturer.
When looking around the net at the many rv and non rv trailering websites (dozens) just about every member that asks the same old question about a better replacement tire than his OEM tires is looking for a better tire.
There are no state/fed laws that enforces the tire placard or say we have to stay with the trailer mfg tire choices .
The tire placard is required by law for the vehicle mfg to list his tire choices . These choices have to be on the trailer at first retail sales.
After that the vehicle owner wants to upgrade the tires before making the first trip or replacing worn out/time out tires, he/she is under no legal obligation to use the same tire on the placard.
The only legal aspect would be if the owner for whatever reason gets weighed and the tires capacity doesn't meet the actual load on them then he may receive a over weight ticket.
IMO the tire placard is a good idea (a place to start) for those who don't have the experience or knowledge to choose a proper/safest tire for his/her tow vehicle or trailer.
