Pirelli has issued a threat to quit F1 if a new contract for beyond this season is not reached soon.
Pirelli's initial three year deal expires at the end of this year and they are pushing hard for a new deal to be made however, there are also some signs of frustration as after a difficult few weeks for the Italian supplier.
Asked what Pirelli's greatest challenge is in 2013, Director of Motorsport Paul Hembery exclaimed on Thursday: "A contract!"
Hembery added he was growing increasingly tired of the spotlight that has shined on Pirelli all season, thanks to the controversial 2013 tyres.
If Pirelli was to remain supplier for 2014, Hembery jibed: "It's probably a year where we will probably step back, be cautious -- zero degradation, no pit stops and they (the teams) can do all the talking."
He continued revealing a September 1 deadline for needing to give the teams the specifications of the 2014 tyres, a tyre that will need to be much different given the changes in the regulations.
"You can imagine how ludicrous that (deadline) is when we have not got contracts in place. Maybe we won't be here," he is quoted as saying.
"Clearly time is already getting too late. Things are getting extremely serious. There comes a time where we will not have time to do the job anymore."
Germany's Auto Sport und Motor believes F1 will not have many options if Pirelli did quit the sport however, reporter Michael Schmidt believes Bernie Ecclestone many have Cooper Avon as a back-up solution.
