Pirelli motorsport boss Mario Isola said there was nothing they could do about the level of spray created by wet tires.

The rain returned for Formula 1’s last outing in Russia, creating flashbacks in Belgium earlier this season where persistent rain prevented the safety car from freeing the drivers for the race.

Fortunately, qualifying for the Russian Grand Prix took place as the rain had stopped several hours before, but the last practice session on Saturday was canceled.

It rained again during the race but in the final stages, allowing the riders to tiptoe up to the checkered flag after putting on intermediate tires.

The riders believe the poor visibility makes racing in the rain extremely difficult, but Isola doesn’t think this is a problem Pirelli can solve.

After all, he says the large amount of spray proves that rain tires do their job of cleaning up water.

“When it comes to tires, there is very little we can do,” he told Motorsport-Total.com.

“Moving the design target wouldn’t be ideal because it would create a gap. I don’t know what could be done in terms of the tires.

“We’re not fixing the problem, we’re probably making it worse. The old rain tire could move 60 liters per second at 300 km / h, we are now at 85 liters.

“If we can’t find a way to stop the spraying, I really don’t know what we can do. Honestly, I don’t have a solution for this.

Maybe the problem isn’t Pirelli or Formula 1 then, rather the tracks themselves?

Isola believes that it would be possible at this time to design an asphalt for better drainage, knowing how much this would cost the promoters of the race.

“With the knowledge we have today, it’s probably possible to design an asphalt that can avoid standing water, or to design tracks with some kind of overhang that just pushes the water away from the track,” suggested Isola.

“It’s not easy, because obviously we can’t ask the organizers to redesign or redo all the tracks.

“With the experience we have gained from the last few races, some things can be done. But if the amount of water is too large, then it is difficult.

“And I think that’s true for any outdoor sport. If it rains too much, any kind of competition will be canceled, be it soccer or other outdoor sports.
