Christian Horner warns Pirelli and suggests that they revert to using last year's tyres

Red Bull boss Christian Horner has warned "someone will get hurt" unless an urgent solution is found following the four separate tyre blow-outs which marred Sunday's British GP.

That sentiment will have been echoed up and down the pitlane on Sunday, with Sebastian Vettel, a director of the Grand Prix Drivers' Association, also highlighting the problem suffered by Perez during Practice Three as proof that Sunday's failures were not isolated incidents. It emerged during the course of the Testgate hearing that the GPDA sought assurances from Pirelli at Monaco that their tyres were safe and Vettel said it would be "very disappointing" if this weekend's issues were a reoccurrence of problems experienced earlier in the season. "First of all, we need to understand exactly what happened today - as well as on Saturday morning with Sergio during Free Practice," said Vettel after retiring from the lead of the race with a gearbox problem. "We have forwarded already our concerns and we got a guarantee that the tyres are safe. If that's the same kind of problem then obviously that is very disappointing, but I can't say that at this stage because I don't know what the exact problem was." Pirelli have promised a full investigation into the failures with another GPDA board member, Jenson Button, describing the incidents which blighted Sunday's race as the cars hurtled through some of Silverstone's fastest segments as "scary". "If it's happening through low-speed corners then that is bad enough, but it is happening at 300kmh along the backstraight which is very scary. It's not just scary for the person driving the car, it's very scary for the person driving behind. The whole tread is coming off the tyre and if that hits you in the head then I don't know what might happen," the 2009 World Champion said. "Something has to be done but something was supposed to be done two races ago, that was the reason for the change in construction - for safety, nothing else. We've had five [tyre failures] here in total, including Checo's on Saturday. The situation is obvious." But although the seriousness of the problem is indeed obvious, a solution is less straightforward. Intriguingly, Button cited the compounds tested by Mercedes at their recent 'private' Pirelli test at Barcelona - for which both team and manufacturer received a reprimand - as he considered how F1 might next move forward. "There are tyres there, I don't know how reliable they are, but they've all been tested - we all know that. Hopefully there will be change for the next race, but it is only next weekend."
