Pirelli remains open to providing F1 with whatever solutions it puts forward but says radical changes to tyres and compound allowance would require more in- and out-of-season testing.
Tyres featured prominently in the recommendations published by the Strategy Group last week. One proposal would give teams free reign to choose two dry compounds (from the current four) ahead of a race weekend next year, while another was the more general aim of creating wider tyres for 2017 as part of the push for a five to six seconds drop in lap times.
Asked if the regulation shakeup would require more in-season testing, Pirelli boss Paul Hembery said: "We'd like some testing, yes. That really also relates to 2017 if you think about it because if you are having cars going four or five seconds quicker you don't want to end up in February, in a cold Jerez, the first time you see a car lapping four or five seconds quicker. That needs a little bit of thinking out for next season. If we stay in the sport I'm quite sure we want to be doing some work in October, November, December before the start.
"You can imagine there could be an extreme situation where somebody does something really crazy and that would look bad for the sport, look bad for Pirelli and look bad for the teams. I don't think many people would remember that the teams made the decision; it will always be our responsibility. We have to find some mid-ground that gives some flexibility to the teams and still allows us to be sure of what is being used. That's what we're looking at."
Hembery confirmed Pirelli has a solution of its own it will table in the coming weeks.
"I think we've got an interesting proposal, I can't wait to explain it to you all actually. But the correct process is that we take it through the FIA through to the teams but certainly the initial reaction is very encouraging. We think it goes a step better than what they're suggesting, actually."
In the event of the tyres opened up to other teams, Hembery says Pirelli would have to avoid making too drastic a change to the existing compounds.
"I think [making compounds closer] is one approach you would take if you thought people were going to do something you weren't happy about, you shift everything to conservative which defeats the object, that's what you would do. We've said no, we'll take on board what people are trying to achieve before we make a change. We understand better what the target is and I think we've come up with a solution, which is different to todays, but that is something good.
"What we wanted to achieve is ... let's take the Barcelona race where some teams maybe were struggling to get the harder choice working but were feeling Mercedes were able to do that. That's a situation we've seen in the past in the years of Red Bull when they had a lot of downforce and could always make the harder compounds work and were pushing in most cases to have harder compounds. They actually want softer compounds now - it depends on the competitive scenario at the time. The main point is teams feel they could adopt a different strategy if they had a little bit more choice."
