I do have to wonder if the dealer is following the regulations and is reporting the failure to NHTSA.
RV owners do not seem to realize that one reason for the poor quality of tires that come on many RVs is IMO due to the failure of anyone to report a majority of tire failures to NHTSA.
The only real requirement is to have the vehicle VIN and the tire DOT serial (complete with date).
If you can capture a few pictures that is good for IF NHTSA needs more information they might ask for pictures so in the original complaint you should tell them you have pictures.
King, in your case you could also say
"I showed a picture of the failure to a tire engineer and he feels the failure is a Tread Separation"
is web site you use to file complaint
