Pirelli will bring their prototype new hard tire for teams to use in practice for this weekend’s British Grand Prix at Silverstone.
Teams did a limited amount of running on the tire in practice in Canada. The revised construction is aimed to prevent a repeat of the tire delaminations seen at some earlier races.
However Pirelli does not yet have the unanimous agreement it requires from teams to use the new tires in a race.
F1’s official tire supplier is bringing its hardest compounds to this weekend’s race and using a new bonding process to guard against delaminations.
“We’ve brought the two hardest compounds to the British Grand Prix,” said Pirelli motorsport director Paul Hembery, “with a new bonding process connecting the tread to the steel belt, which is designed to eliminate the isolated delamination issues to reach a unanimous agreement about this.”
“However, we do still have that possibility on stand-by should it be required in future. During free practice at Silverstone we will have the same prototype hard seen earlier this season.
“The actual construction of the tire won’t change, as the teams weren’t able tire available that we tried out on Friday in Spain, aimed at even greater durability than our current hard. This is in order to give the teams the chance to test this new compound on a different track to collect more data.”
