There has been some criticism of Pirelli tires at the Azerbaijan GP after two unexpected and sudden blowouts in the race that also cost leader Max Verstappen the win.
Now Pirelli is responding and will use a new tire design at the British GP. For this, F1 teams will have to test this new tire next race weekend at the Austrian GP.
The tire manufacturer had to take some criticism when there were two accidents on the start-finish straight in Baku. The reaction to this made Pirelli increase the monitoring of the starting pressures as some teams had lowered the tire pressure in the race.
They asked if it was possible for it to use a more robust construction, but with a stiffer sidewall than the current tires. As a result, the C4 tire will be used at the Red Bull Ring as the C1, C2 and C3 tires will be needed at Silverstone. This is because harder tires have always been used at Silverstone.
Pirelli explained: “Pirelli, in agreement with the FIA, Formula 1 and the teams, will test a new rear construction of tire in free practice at the Austrian Grand Prix on Friday 2 July to evaluate its effectiveness to further improve robustness of the tires.”
“This decision has been taken in addition to the recently issued technical directive and the latest starting parameters prescribed by Pirelli, in light of the fact that it is not currently possible to monitor running conditions in real time.”
“This will remain the case until next year, when standard Tire Pressure Monitoring System (TPMS) sensors will be introduced across all teams.”
“Next Friday, each driver will have two sets of these new tires available for use during either free practice session.”
“If the test is successful, the new rear specification will be introduced from the British Grand Prix onwards, replacing the current specification. The new rear construction incorporates some elements that have been developed for use in the latest 18-inch Formula 1 tires from 2022.”
“With this new structure Pirelli provides a tire that can guarantee even greater levels of integrity under the extreme conditions that can be generated by the current cars.”
