Ferrari and Pirelli are set for talks over Sebastian Vettel's Belgian Grand Prix tyre failure, as both parties worked on Monday to try to find answers as to what exactly happened.
Investigations into the exact cause of Vettel's tyre failure are ongoing, as both team and tyre supplier want to fully understand why the right rear failed on the penultimate lap.
Although Pirelli remains adamant that the failure was related to tyre wear – with the set of mediums having completed 28 laps – there remains some scepticism about whether or not that was the key contributing factor.
The laptimes that Vettel was producing at the time of the failure did not suggest he had hit a performance drop-off, while it is understood that there was no indication on Ferrari's data of variations in tyre temperature or pressure to suggest that a problem was imminent.
Furthermore, there are suggestions that initial analysis of Vettel's remaining tyres have found no evidence of excessive wear either.
The situation is further intriguing because a failure through over use would likely manifest itself on the most stressed corner of the car, which around Spa is the front left.
Pirelli motorsport director Paul Hembery has admitted that his company and Ferrari will need to discuss the situation as soon as they have the answers.
"Teams make decisions based on the data they have and in this case there is something that did not work out between us and them," he explained.
"It's easy to say now, but we have always had good co-operation with Ferrari. So we will sit at a table to find the best solutions."
Ferrari ready to respond
Ferrari team principal Mauricio Arrivabene was eager not to get drawn in to a war of words with Pirelli over accusations it pushed for too long with the tyres.
However, he said that it was important the truth came out when the full details of what happened to Vettel's tyre were clear.
"First I want to make some checks with the technicians because we want to be fair and do not want in any way to open the controversy between us and the Pirelli," he said.
"What has happened has happened. If someone wants to attack us we are ready to respond."
