Formula 1 tyre supplier Pirelli says it has concluded its investigation into the tyre failure suffered by Ferrari driver Sebastian Vettel at the Belgian Grand Prix.
Vettel was attempting a one-stop strategy at Spa-Francorchamps but his right rear Prime tyre failed on the penultimate lap of the race.
Vettel reacted angrily to the failure, criticising Pirelli and claiming that such incidents were unacceptable, citing Nico Rosberg's failure during practice as evidence.
Rosberg's failure was attributed to external cuts and Pirelli now says that an investigation into Vettel's incident has been concluded and that the findings will be presented at this weekend's Italian Grand Prix, a home race for both Ferrari and Pirelli.
Pirelli has opted to go one step softer with its Monza compounds compared to 2014 and will provide the Medium and Soft tyres this weekend.
"We’re expecting a fair degree of wear and degradation, so as always the work done during free practice will be very important when it comes to calculating the optimal strategy," said Pirelli's Paul Hembery.
"With the two compounds potentially quite closely matched in terms of pace, this opens up a few options."
