Pirelli's head of motorsport Mario Isola says that testing 18-inch wheels for 2021 will be difficult as teams are not aware of the car regulations for the season.
Formula 1 is set to see the introduction of new engine and aerodynamic regulations in 2021, however teams have not been made fully aware of what these changes will entail.
Renault's F1 president Jerome Stoll recently stated that he would be soon meeting with Liberty Media CEO Chase Carey to discuss the progress made on the new rules. But with Pirelli keen to start testing its brand new tyres that will be introduced in two years' time, Isola says that for now, it looks like a difficult task ahead.
"We are now focused on the development for 2020, we will soon announce the test plan for 2019 in order to develop tyres for 2020," Isola told GPToday.net in Barcelona.
"We decided to have a concentrated development test for 2020 until the beginning of September, so we are planning to finish the developments for 2020 at the beginning of September as we would like to move onto 18-inch tyre testing from end of September onwards.
"The discussion on new cars to fit the bigger tyres and how to allocate the test sessions is ongoing with the FIA and the teams because we have an issue that the 2021 regulations are not defined yet. That means it's difficult for new teams to supply mule cars if they don't what performance is expected for 2021."
For the upcoming season, Pirelli has revised how it will identify its tyres while also stripping its range from seven dry compounds to five. It will also use the same colour coding each weekend, regardless of the compound.
"We have homologated five compounds and we will select compounds in accordance with the track layout, so the usual system so when you see white tyres, its the hardest of the three, yellow is the one in the middle and red is the softest," Isola stated.
"We have a new construction, it's designed to try and manage better the heat that is going into the tyre we did this with new materials in the construction, new materials in the compounds that are deisned with this target in mind and also with a reduced thread that we introduced last year at two races."

Am I the only that doesn't really dig those 18-inch wheels? I hate being that angry old fan that always whines about "How good F1 was back when [fill in the blank]. But I honestly don't understand this change. I understand it even less than the halo. Is anyone reading this comment thinking that the cars will look better with those wheels? Maybe I'm one of the few that doesn't quite see it.
