Paul Hembery, Pirelli's motorsport director, has promised to toughen up his tyres for next month's British Grand Prix.
The Spanish Grand Prix came under fire from a number of drivers after featuring 82 pit stops as teams fought with the complexities of this season's tyres. Half the cars made four stops in Sunday's race and some more than that.
Hembery said on Monday: "We will make changes. We want to bring something to Silverstone to make sure we are back on track with two or three stops.
"That could be compound changes or structure changes. We will decide that in a week. We can imagine, though, if we make a change, it might be seen that we are making tyres for Red Bull, in particular; that Red Bull are pushing to have a change and, if we do something that helps them, we can understand that Lotus and Ferrari won't be happy. So it's a very difficult situation we sometimes find ourselves in."
Lewis Hamilton joined in the criticism on Monday after Mercedes again struggled to fight excessive tyre wear. "There was just no grip," he said. "It was like sliding around on all fours, just tiptoeing around. It doesn't matter whether I go slow or go fast – it doesn't do anything different. It is very, very strange. One of the strangest feelings I have had for a long time.
"There is obviously a key to getting the tyres to work and it is trying to find the key to unlock the potential of the tyres. The car is great – it is just the way that we use our tyres or it might be the way we prepare our tyres."
Hembery admitted that there were too many stops at the Circuit de Catalunya. "We had four pit stops and that's one too many. We've always said we were aiming for between two and three. It's very complex, we understand, for fans to follow four pit stops. We admit we don't really want to see four pit stops on a regular basis. We've only seen it once before, in Turkey in 2011.
"The cars are pushing a lot harder than we've seen in the past. The downforce levels are getting close to 2011, when the cars had the blown diffuser. We are also pushing much harder the compounds so combine those two together and we are working the compounds much more than we have in the past."
There is a certain sympathy for Hembery. He is being harangued by everyone in the paddock as he tries to be even-handed.
Yet it is not Pirelli's responsibility to stop Red Bull winning another double championship. That is a job for Ferrari, Lotus and Mercedes. And what really matters, crucially, is not the number of stops but that cars should race each other between them.
For the purist, watching drivers going slowly to conserve their rubber, while doing nothing to resist being overtaken because it is contrary to the team strategy, is the very antithesis of what Formula One is about. For these people, on an entertainment level, the Spanish Grand Prix ranked not much better than a day out on the M25.
The introduction of DRS and Kers has already promoted too much cheap overtaking; the tyre situation has made it much, much worse. Tyres, always important in Formula One, are now too dominant a feature. Aero and mechanics are hardly talked about.
On Sunday evening Jenson Button rightly described the situation as a "right mess" with cars going round 12 seconds slower than in qualifying.
Paul di Resta asked his team to tell him what was going on, and even the race winner, Fernando Alonso, said it was too confusing for spectators.
Formula One, in an effort to eradicate processional races, has created a contrivance. It no longer means anything, and is far more tedious than the reality of racing. At the moment, F1 is scarcely a sport at all.
Spectators don't go home from a race saying: "Wow, what a lot of pit stops we saw!"
