Pirelli will not race its new rear tyres at the British Grand Prix as planned after wet weather on Friday in Canada limited the teams' testing mileage on the new structure.

Pirelli originally planned to introduce the tyre in Montreal but could not get unanimous agreement from all the teams and so agreed to supply the new tyres in practice before intending to roll out a full introduction at Silverstone. The new tyre features a Kevlar belt rather than a steel one and is designed to reduce the risk of delamination, but a lower operating temperature means it could also have an impact on performance for some teams.

Pirelli motorsport boss Paul Hembery confirmed the new tyre would not race in Great Britain but said his engineers had come up with a new bonding process for the current tyres that should reduce the risk of delamination.

"We are not going to race with the new tyre as we did not get much of a chance to test it here [in Canada]," he told Autosport. "We have some internal specification changes - process changes - that we think will go the full way to curing the delamination issue that we have seen.

"That is good from many points of view, as it means teams will be working with the same tyre they started the year with. But it is probably not good for some teams that are struggling with the front tyre."
