Like most teams, Red Bull implemented the 2013-spec Pirellis at the start of the season, which has led the German to finishing third in Melbourne before winning the Malaysian Grand Prix last month.
However, Vettel admits that he and his team are still getting used to their new tyres.
"Obviously we learned quite a bit from the first two races. China will be different again, different circuit, different climate," Vettel told Sky Sports News.
"So I think we're still in the learning process. Obviously the first two races helped a lot and I think it was very obvious to see that working with the tyres and trying to make the tyres last is crucial. It determines your strategy and therefore determines your race and the result.
"I think we've still got a lot to learn but we made some improvements and we tweaked the car a little bit to help that. But on the other hand we'll still have to come here, come to China, set the car up on Friday, see where we are, see how long the tyres last and go from there."
The Chinese Grand Prix takes place this Sunday.
