Silverstone is also changing the Beckets/Chapel kerbs to prevent cuts.
On loads Pirelli only have the data teams give them to chose the compounds. I know they have data from last year, but for predicting this years
behaviour they rely on the teams. The fact the loads were higher than expected suggests the teams have been holding back on their data.
I think the problem wasn’t with the compounds but the structure of the tyre. I believe the structure stays the same across the whole range of compounds. When they give a stint life, in laps, for a compound they are a estimating a performance limit due either to wear or thermal degradation. They use tyre pressures to try to ensure the structural, fatigue, limit is beyond the longest stint they expect. They got it wrong due probably to a combination of higher race pace loads and mechanical damage suspected to come from the kerbs at turn 14.
In rejecting the proposed more durable 2020 tyre structure the teams served up Pirelli a double whammy. By using last years tyres their baseline aero model didn’t change and they could press on to produce more downforce. If they’d gone with the proposed tyres the baseline would have changed and they would possibly have struggled to match the gains they have made.
