Nico Muller set the pace on a wet second day of Formula Renault 3.5 testing at Barcelona.
The Draco driver set a best of 1m48.116s early in the morning session and the tricky conditions that his benchmark time would not be bettered later in the day.
He said: “The new treads are at their best when there's a lot of water on the track. They offer an amazing amount of grip in extreme conditions.
“We need to learn how to look after these tyres, though, because they get worn really quickly if you're not careful and then you're in whole lot of trouble.
“We've still got a lot of work to do in the dry, but having the chance to work on a wet track has given us some useful preparation for the season ahead.”
Kevin Magnussen, quickest on the opening day in Barcelona, was second fastest and less than two tenths of a second behind Muller.
Marco Sorensen, Andre Negrao and Robin Frijns completed the top five.
Richie Stanaway was fastest in the afternoon session but conditions ensured he would not match Muller's leading time and was almost two seconds slower.
