Pirelli explains tyre problem in Monza

Kimi Riding Hood has lost the Formula One race of Monza to its tires due to excessive bladder formation (so-called blistering). According to Pirelli, the fact that he could no longer turn on Lewis Hamilton due to this problem in the final track was due to a chain of unfortunate circumstances.

Started this already on Friday in Free Training, because the teams could not collect enough Longrun data there. First, the first session was heavily influenced by rain, so the teams had to pack more work into the second session. However, this was also shortened by around 20 minutes after Marcus Ericsson (Clean)’s serious accident.

The teams could therefore only drive long runs with a maximum length of ten laps in the end, too little to understand how the tyre behaves over the racing distance. So you try to predict what’s gonna happen. But this is not linear,”explains Pirelli manager Mario Isola.

Of course, this was the same for all teams, but then Racing Kings were visited by special circumstances that made his life difficult. After he stopped boxing, he had to push harder and longer to avoid being overtaken by Lewis Hamilton. In addition, he later hung behind his teammate Valtteri Bottas, lost traction and slipped more, which eventually caused the bubble formation.

This results in bubble formation

“The soft tyre is more susceptible to bubble formation because the wear is so low,” says Isola. ” With low wear and tear, high temperatures are generated in the mixture, causing bubbles to form.”Even the backfall behind Bottas would not have been so tragic on the Supersoft, as it has more grip, which would have made rakes less slippery.” And if the tyre is new at the beginning, and you push, then you have even more rubber, and the effect is amplified,”says Isola.

Riding kites could no longer defend themselves against Hamilton in the final phase and had to let him pull into curve one almost without a fight. Nevertheless, he still dragged himself to second place.
