Plans for revised tyre rules in 2016 remain in limbo after the F1 teams were unable to decide on the details in a meeting on Thursday night.
The subject was discussed by the team managers and the FIA at a gathering of the Sporting Working Committee, where the other key item on the agenda was refuelling (see separate story).
The original proposal, put forward by Force India, was for teams to be allowed to chose in advance which of the four tyre compounds they want to use each race weekend. Several more detailed plans were presented in the meeting, including versions proposed by Pirelli, Red Bull, Mercedes and McLaren.
Among the ideas discussed were having as many as six compounds, three compounds in use per weekend, drivers not starting on the tyres that they qualified with, and a ‘joker’ system that allows teams to select their own tyres four or five times a year.
As noted previously Pirelli is concerned about teams choosing an extreme compound, experiencing problems and then blaming the tyre supplier for any shortcomings. The Italian company made that clear when summing up the aims of its own proposal, saying that any plan should “not jeopardise safety or the tyre supplier reputation,” while at the same time “providing more and better publicity for the tyre supplier, making the tyre choice and tyre usage a talking point before and during the race weekend.”
Pirelli also gave some idea of the logistics involved by suggesting that teams choose their tyres for the first races of the season as early as November of the previous year, and then make their selections for the latter part of the season in April.

Joker system three or four times a year…
There lies the problem. Keep looking for gimmicks to “fix” F1.
The likes of Enzo Ferrari and Colin Chapman must be rolling in their graves.
“Unable to agree”…
Can we just get a tyre war going again? Bring Michelin back, and keep Pirelli and Bridgestone on as well – 3 tyre suppliers and free choice of tyres for all the teams – the grip would be terrific and we would see real racing.
each manufacturer would do what was done before …tailor their tyres to the team which they think that gives them the best chance of wins
so only 3 teams will ever have a chance
so back to the ferrari /bridgestone position …we will fit your tyres to our road cars if you tailor your F1 tyres to our cars / renault [ french government controlled ] / michelin [ also french ] we are you biggest road car customer etc
it’s like the man from toro rosso said for the others
They should just go back to what we had Pre-94. Take all dry compounds to every race & let teams run what they want, No mandatory stops to run 2 compounds, No forced pit stops/strategy & just let teams do what they want with the tyres available.
Want to pick the hard’s & run non-stop.. Fine. Want to run the super-softs & stop 2-3 times…Fine.
Open up full strategic freedom with tyres, don’t handicap them with mandatory stops, Forcing them to run a compound there car or driver doesn’t like or having something like we currently do where everyone is pretty much forced down the same route.
