Lewis Hamilton has branded the tyre issues that disrupted the British Grand Prix as 'unacceptable'.
A host of drivers suffered punctures to their Pirelli tyres early on in the race, with Hamilton, Felipe Massa and Jean-Eric Vergne all suffering rear-left blowouts at the same point on the Silverstone track, prompting the safety car to be deployed.
Later on both Sergio Perez and Esteban Gutierrez would also suffer punctures, with the McLaren man forced to retire from the race.
A range of theories are currently being explored, with some suggesting the kerb on the exit towards the Wellington straight was to blame, while others suggest it is a problem with the Pirelli tyres.
Hamilton, who was leading his home race at the time but was forced into the pits on lap seven and re-emerged in last place only to fight his way up to fourth, says the problem with punctures has become a real safety issue.
"Safety is the biggest issue," he said. "It's unacceptable really."
He added: It's only when someone gets hurt that someone will be doing something about it.
"I think it's a waste of time talking to the FIA, and if they don't do anything that says a lot about them."
Pirelli say they are currently investigating the punctures, but have already ruled out a new bonding process used on the tyres as the cause.
Mercedes received a reprimand and were banned from the young drivers test for taking part in an illegal in-season testing session with Pirelli after the Spanish Grand Prix in May.
"We had that tyre test to develop and improve the tyre," Hamilton continued. "after that they didn't do anything about it."
The 2008 world champions' Mercedes team-mate Nico Rosberg took the chequered flag on Sunday, taking advantage of the misfortune of Hamilton and Red Bull's Sebastian Vettel, who retired for the first time this season because a gearbox problem.
There was a chance he could have penalised for failing to slow for a yellow flag during the race - however stewards opted against giving him a time penalty and doled out a reprimand instead, meaning the German kept his second race win of the season.
