Lewis Hamilton will not be in action for Ferrari in the Pirelli tyre test at Mugello
Lewis Hamilton is expected to miss the Pirelli tyre test at Mugello on Friday due to his dog Roscoe battling ill health, as Hamilton shared on social media. The seven-time world champion will be replaced by reserve driver Zhou Guanyu during the test alongside Charles Leclerc. The Pirelli test will feature the new 2026 tyres with changes in diameter and width, coinciding with upcoming technical regulations for Formula 1. Other teams, like Ferrari and Haas, will also participate in the tyre test at Mugello, with Haas confirming Romain Grosjean’s return to driving an F1 car since his last race in Bahrain 2020. Mercedes boss Toto Wolff previously promised Grosjean an outing in a Silver Arrow after his F1 career ended abruptly due to a crash, yet this plan has not yet come to fruition after five years.
