For testing purposes 18 inch tires od Pirelli only older Formula 1 race cars can be used. In fact. But Formula 1 sports rules allows a gap that can be used for test drives Pirelli they also use the new 2021 generation race cars, and it could benefit the most from that McLaren.
McLaren is the only team for the season 2021 change engine supplier as they will now use Renault instead Mercedes. This means that the British team has racing cars of a younger past, but due to a change of engine partner may no longer be used. That would be it McLaren excluded from the test Pirelli's gum. For v Article 10.5 sports rules are in paragraph c)describing the testing of tires reads: "Only race cars that have competed in the 2018, 2019 or 2020 seasons can - appropriately modified - take part in such a tire test, which is carried out before the first event of the 2021 season."
Decisive in this interpretation, however, is that the rules govern only procedure until the start of the season 2021, but not the procedure during the competition season. And this can be understood as allowing teams to make needs Pirelli's use rubber test - otherwise slightly modified - this year’s race cars, as soon as the first race of the season is over, because no tire tests have been scheduled for the time before the start of the season. For teams Formula 1 would be the use of current race cars Win-Win situation. They will not have to convert older racing cars, but they could take additional test laps with 2021 racing cars. And as it is known, every kilometer helps in some way.
Otherwise, it's about that Article 10.5 c) also written: "There will be 25 test days available this year, the sole purpose of which is to allow tire providers to try out design improvements to their products.”But also from the side Pirelli prescribed setting and prohibited changes on race car settings, teams will be able to gain new insights about their race cars. However, there is one in sports policy strict restriction or Prohibition: Testing parts for the season 2022 is prohibited. In doing so again Article 10.5 c)"In addition to tires and rims, a race car or a partial component intended to collect technical information on the 2022 regulations is not permitted.“New 18 inches tires will be preferably tested in total 25 days, at the suggestion of Pirelli.
Originally they should new tire dimensions debut as early as this season, but due to the coronavirus crisis, these are along with new technical rules moved to the year 2022, to which it must Pirelli still to prepare. Mario isola, the sports boss of the Italian manufacturer, expressed doubts last November whether it will Pirelli could even run the entire test program this year. “Getting under the roof of these 25 test days will be very difficult." Island he hinted that Pirelli wanted to test directly after the races, which has not yet been confirmed. Until the final test 2021 in Abu Dhabi in December, must have Pirelli my 18 inch tires ready to be launched as planned in the 2022 season.
