I have not, but the protections in place through the Department of Transportation won't allow a new tire to be manufactured and sold in the US without meeting basic safety standards. You can see these ratings of the tire on the sidewall. https://www.tirerack.com/tires/tiretech/techpage.jsp? techid=172
As for "recommended for automatic transmission" I don't see how a tire would know the transmission style. It's more likely a computer programmer's way of linking together all parts for a specific vehicle, that is 1999 Dodge trucks with automatic transmissions. In other words, more marketing than technical. In any case, almost all vehicles sold in the US are now automatics. Which is too bad for many reasons, like the left leg exercise automatic drivers miss out on. :)
