With World Superbike’s stop at Monza being massively disrupted by the combination of the track’s demanding layout and Pirelli’s melting rain tires, the Italian tire company has taken the brunt of criticism from fans, teams, and riders for its handling of the two races at the historic circuit. With the long straights and high speeds of Monza proving to be a challenge in even normal conditions, the issue of tires became increasingly important as it was discovered that the compound used in Pirelli’s rain tires could not handle the center-line heat caused by the Italian track, even in full-wet conditions.
WSBK fans watched as riders blew through rain tires in just a matter of two or three laps during the wet Superpole qualifying session on Saturday, and when the rain showed up again on Sunday, the riders had said they had enough of the nonsense. Though not encountering fully-wet conditions, Pirelli’s intermediate tire was ruled out of the equation, as it uses the same compound as the rain tire, albeit with fewer groves. So, Pirelli’s solution to the problem was to take racing slicks of different compound, presumably one that could handle the heat of the track, and cut them to into makeshift intermediate tires. Expecting riders to go two races on a pair, the WSBK paddock was less-than-enthusiastic with this remedy.
With the riders essentially causing a mutiny on the starting grid, Race 1 at Monza was cancelled, while Race 2 was delayed for dryer conditions. Once the rain returned halfway through the race though, riders again raised their arms to signal the stoppage of the competition. Since they completed half of the race, only half points were awarded, but that left for some interesting comments in the paddock. Responding to the criticism of how it handled the Monza weekend, Pirelli has released a press statement that shifts the blame back to the World Superbike teams. Read the company’s statement in its entirety after the jump.
The weekend at Monza was most certainly conditioned from Saturday by weather conditions which were extremely unstable, with nice weather, suddenly alternating with rain and at times even with hail. As for Superbike, first and foremost I would like to make an important note on Saturday’s Superpole: Pirelli consistently recommended that the teams and riders use the intermediate tyres which were available to them.
This advice, however, was completely ignored since all of the riders used rain tyres. Clearly the reason for this was the fact that the track was completely dry in places, while in others it was wet due to the trees along the track which kept the asphalt from drying. The rain tyres run well at 50°-60°, but on the two consecutive straight stretches, which were completely dry, they obviously reached temperatures well above 200°. This caused a meltdown of the compound in the centre.
I would also like to reassure everyone on this point that Pirelli tyres have a particular structure with a steel belt, and therefore it is absolutely impossible for them to explode. That said, on Sunday the riders in the Superstock classes raced as scheduled, in conditions which were even worse than those during the Superbike races, using the rain tyres on the front and the intermediate or race tyres on the rear.
In Supersport, as further proof that the Pirelli rain tyres can most definitely sustain an entire race without any problems, the riders raced and finished on rain tyres. So it was a shame that, although the Superbike riders had two intermediate solutions available to them for the rear, they expected only to use the racing slicks. Once the race began, in any case, it was clear that even in those conditions a good race could be run.
