B ei 350 km /h on the straight, every point on a tire comes into contact with the road again and again. The breaks are few. There are also four fast right-hand bends in Monza, where the front left tire is heavily loaded: Curva Grande, Lesmo I, Lesmo II and Parabolica. These are the ingredients for a tire to get too hot and, in the worst case, blister. That is why all tire manufacturers in Monza have brought their hardest rubber compounds with them. It doesn't matter whether it was Goodyear, Michelin or Bridgestone.
Two stops in Monza?
That is also the case at Pirelli. The Italian tire manufacturer has also reduced the thickness of the tread by 0.3 millimeters. This corresponds to about ten percent of the total thickness.
The thinner the rubber layer, the less the rubber can work. This reduces the build-up of heat. However, less rubber also means that the tire approaches the critical wear limit more quickly. Pirelli had already used the thinner running surfaces in Spa. After practice, three teams showed signs of increased wear, but that turned out to be a blind alarm in the race.
Things could get a little more critical in Monza. After the first 90 minutes of training, almost all teams reported problems with increased wear. Especially on the front left. In order to achieve 20 to 30 laps with one set of tires, the teams swapped the front tires from left to right and vice versa at halftime. A McLaren engineer predicts: 'The tire problem could mean that everyone has to make at least two stops on Sunday. Monza was actually always a classic one-stop race.'
