The Qatar GP shocked each engineers and followers with the surprising sturdiness of the C2 Medium tire in the course of the first stint. Whereas this initially made the race considerably monotonous, the following punctures suffered by Sainz and Hamilton created a extremely unsure state of affairs that saved us on edge till the end.
At this level, it’s tough to find out whether or not the punctures have been brought on by extreme tire put on or particles on the monitor. Pirelli’s motorsport director, Mario Isola, addressed the problem: “Throughout the race, each Carlos Sainz and Lewis Hamilton skilled punctures on their entrance left tires. We are going to totally analyze the stays of these tires, in addition to a collection of others, following our commonplace process. Our technicians in Milan can even depend on telemetry information and onboard footage. We are going to perform the standard checks concerning the stress positioned on the tires.”
Technique Recap
The commonest technique was the Medium-Laborious mixture, utilized by race winner Verstappen, Leclerc, Piastri, Gasly, Sainz, Zhou, Norris, and Hamilton. Russell opted for a Medium-Laborious-Laborious technique, having pitted early and later switched to a brand new C1 set beneath the Security Automotive.
Alonso and Bottas selected Medium-Laborious-Medium, avoiding a stint on the C1 tire, with Alonso utilizing it for only one lap. Tsunoda and Lawson went with Medium-Laborious-Smooth, whereas Albon adopted Medium-Smooth-Smooth. Retirements included Nico Hulkenberg, Sergio Perez (reportedly attributable to a hydraulic challenge), Stroll, Colapinto, and Ocon.
Medium Tires Pushed to the Restrict
This evaluation focuses on understanding why drivers pushed the Medium tires to their limits. Whereas it’s not sure that tire put on induced Carlos Sainz and Lewis Hamilton’s punctures, it seems to have been a contributing issue, so it’s value exploring why this case arose.
Pirelli had initially estimated the primary pit cease to happen between laps 16 and 24. It was thought potential to increase this barely, however nobody anticipated stints of over 27-28 laps on the C2. The explanation for pushing past the expected restrict is easy.
An undercut was anticipated to be extremely efficient, however for it to work, drivers wanted clear monitor after rejoining. This didn’t occur after Russell’s pit cease, the place a sluggish tire change on the rear proper value him about 5 additional seconds (whole cease time: 7 seconds). He rejoined behind Alonso and, regardless of being sooner, was pressured to match Fernando’s tempo because of the issue of overtaking in Lusail. Seeing this, different drivers averted pitting early to remain out of site visitors, stretching the C2 to its restrict.
Mario Isola partially echoed this evaluation: “The monitor may be very demanding when it comes to vitality exerted on the tires and tread put on. This mix of things can create a state of affairs the place put on reaches important ranges, with groups making an attempt to increase the primary stint as a lot as potential to maximise outcomes.”
Max Verstappen and Lando Norris pushed the compound to its restrict, however Max had the higher tempo. Simply earlier than the punctures for Sainz and Hamilton, Lando Norris’s Mediums have been starting to degrade, and he would have wanted to pit quickly anyway.
Fernando Alonso Confirms a One-Cease Race
The aftermath of Carlos Sainz and Lewis Hamilton’s punctures is obvious: those that stayed on Hards with out switching to a brand new set of Mediums within the last levels made the precise resolution. Making a further cease beneath such frequent Security Automotive intervals would have been counterproductive and price positions. Fernando Alonso, for example, fell from being forward of Russell to ending behind Gasly and Sainz after his double cease.
Fernando and Aston Martin misjudged the Laborious tire’s potential. The C1 was the perfect compound for the ultimate stint. Lando Norris, for instance, set his quickest lap on the 56th lap with this compound, finishing 21 laps on it with a time of 1:22.384.
