Does the item Smooth Rock only work with the move Sandstorm or can it work with the ability Sand Stream?

Question

I have a Tyranitar with the Sand Stream ability and I was wondering if I give it the Smooth Rock will it make the sand Stream ability go longer or does the smooth Rock only work with the move sandstorm?

Answer 1

If the Pokémon holding this item creates a sandstorm with the move Sandstorm, the Ability Sand Stream, the Ability Sand Spit, or the move Max Rockfall, it lasts eight turns instead of five turns. (Prior to Generation VI, it has no effect on Sand Stream, which creates a sandstorm with indefinite length in those games.)
