Pirelli says Sebastian Vettel's high-speed tyre failure towards the end of the Belgian Grand Prix wouldn't have happened had its proposal from 2013 to limit the maximum number of laps a tyre should be used had been adopted.

The Italian firm has come under scrutiny after Vettel vented his fury in the wake of a dramatic tyre failure less than two laps from the end of the Belgian Grand Prix, with the German being backed up by Nico Rosberg, who suffered his own high-speed - albeit unrelated - puncture during free practice.

The circumstance of Vettel's tyre failure is focused on the fact he had completed 28 laps on the medium compound after adopting an alternative one-stop strategy in an effort to play himself into contention.

Since Pirelli had anticipated two or three stops prior to the race, it proceeded to deflect Vettel's expletive-laden criticism by suggesting immediately after the race that it was Ferrari's fault for pushing the wear-life of the tyre until it failed.

Now Pirelli has hit back again with a curt and direct message to teams, 'underlining' that its preference to set a limit to the number of laps a single compound can be used was rejected. Had it been in place, Vettel's tyre failure wouldn't have occurred.

"Regarding what happened today at the Belgian Grand Prix, Pirelli underlines that...

"Our request of two years ago to fix a maximum limit to the number of laps that can be run with the same tyres was not listened to.

"In November 2013, Pirelli requested that there should be rules to govern the maximum number of laps that can be driven on the same set of tyres, among other parameters to do with correct tyre usage. This request was not accepted.

"The proposal put forward a maximum distance equivalent to 50% of the grand prix distance for the prime tyre and 30% for the option. These conditions, if applied today at Spa, would have limited the maximum number of laps on the medium compound to 22."

The furore comes ahead of Pirelli and Ferrari's home race, a situation that could be complicated further by the fact that the tyre firm has opted for a more aggressive compound combination after deciding to use soft and medium rubber, rather than last year's medium and hard compounds.
