Pirelli has revised the tyre options that will be available for teams during the Hungarian Grand Prix later this month.
Originally, the tyre supplier had intended to take the hard and medium tyres to the Hungaroring in a move that was seen to be conservative by a number of teams in the paddock.
However, the recent changes announced by Pirelli following the failures in the British Grand Prix have in turn led to changes being made to the rubber that teams will use in Budapest.
The decision to revert to a tyre that features the 2012 construction alongside the 2013 compounds will mean Pirelli now takes the soft and medium tyres to the race; the same combination that was provided twelve months ago.
"The change to the 2012 construction means that Hungary doesn't require such a hard compound now," a spokeswoman told the BBC
The 'new' tyres will be tested during the upcoming Young Driver Test at Silverstone, although Mercedes will only sample the tyres for the first time in Hungary having been banned from taking part following its tyre test in Barcelona earlier in the year.
