Hamilton Wraps Up Pirelli Wet Tire Test at Fiorano

Lewis Hamilton wrapped up a two-day Pirelli tire testing session at Ferrari's private Fiorano circuit on Friday, covering 297 laps and 884 kilometers to aid development of new wet weather compounds for Formula 1's 2027 regulations.

The seven-time world champion piloted Ferrari's SF-26 car across Thursday and Friday, with the track artificially irrigated to simulate consistent wet conditions despite ambient temperatures reaching 21 to 22 degrees Celsius. Pirelli, Formula 1's sole tire supplier, used the session to evaluate prototype full wet tires featuring a revised tread pattern, which had been initially tested the previous week at Suzuka by Red Bull and Racing Bulls teams. Engineers aimed to extend the operating range of the Cinturato Full Wet tire to handle lighter rainfall more effectively, addressing long-standing driver concerns about performance in varying wet scenarios.

On Thursday, Hamilton completed 142 laps totaling 423 kilometers, starting with multiple configurations of full wet tires in the morning and early afternoon before shifting to variants of the Cinturato Intermediate tire. This allowed Pirelli to assess crossover thresholds between the compounds, crucial...
