The McLaren driver is renowned for being particularly easy on his tyres, but it would appear that he has been caught out by the new compounds.
Speaking to Spanish publication AS, Perez said “I don’t know what to say. It is worrying and I hope it changes for the first race. It doesn’t matter what you do, what talent you have.”
Pirelli did work on making the tyres less durable for this season following many one-stop races in 2012. The changes have not been welcomed by Perez though.
“It is an unpleasant surprise. The cool temperatures are making it worse,” he said to Speedweek.
“In Melbourne it will probably be better, otherwise we will be doing seven or ten pitstops.”
Despite his tyre woes, Perez managed to top the second day of testing in Barcelona, ahead of Sebastian Vettel.
The Toro Rosso driver even said “I’m not sure if what the tyres are doing is what they had expected.”
All of these changes could make the beginning of the season something of a lottery, where looking after your tyres is key to winning races and forging a championship lead early on. The shake up is already beginning.
