Hard F1 tyres only good for photos in Spanish GP, Perez feels

Pirelli has brought its hardest-possible tyre allocation to Barcelona with the hard, medium and soft compounds.

Teams are also still restricted on how many sets of each compound they can use during a weekend, with Pirelli making those selections for F1's new-for-2017 cars until the next round in Monaco.

Red Bull's Daniel Ricciardo believes the selection is "not good for anyone" and Perez agrees that the weekend's mandatory two sets of the hardest compound will be of no use.

"I think the hard will be just for the pictures, basically," the Force India driver said.

"We will not use it at all."

Perez also raised doubts about using the medium compound, of which teams will have four sets, based on it needing hot conditions to get into the right operating window.

"Maybe with the rougher Tarmac, with an aggressive track [it would be fine]," he added.

"It is very different to Russia with the higher track temperatures.

"So maybe, maybe, maybe, it can work. But too many maybes."

Teams will have seven sets of the soft compound, but Perez believes Pirelli could have picked its softest rubber, including the ultra-soft.

"I would have definitely have gone for super-soft, at the very least," he added.

"We could have gone even to the ultra-soft around here."

Haas driver Romain Grosjean agreed that the tyres could have been softer, based on how they performed during pre-season testing at the circuit

"We used the ultra soft in winter testing and it wasn't that bad," said the Frenchman.

"[Sebastian] Vettel did 25 laps on them, so we could have had super soft, soft and medium.

"Plus the tyre presciption pressures are particularly high as well."
