I have heard this rumor before but never seen any solid information on it.
Do you have a link or something?
This is from tire rack:
"When looking at UTQG ratings it is important to realize that the Department of Transportation does not conduct the tests. The grades are assigned by the tire manufacturers based on their test results or those conducted by an independent testing company they have hired. "
So the tire makers can do their own tests, report whatever thay wish, and roll the dice on someone calling the government in before they change /drop the tire in question.
