In previous races we have seen that when the tyres have got cut or damaged the tread platform strips off (often in spectacular fashion) but as the rear tyres have a steel band running through them it enables the driver to return to the pits with the carcase of the tyre intact.
Many are questioning the reason we see the damage to these tyres in the first place and I have a theory for this too. The tyres have suffered damage on the same circuits that the GP2 series races have been conducted at on the same weekend. Bahrain, Barcelona and now Silverstone so without meaning to be Inspector Clouseau we would have to assume that this has some bearing. Whether it be that the track simply isn't being swept well enough between the sessions with shards left around the track or whether it's a problem caused by Pirelli's GP2/3 tyres leaving debris on the circuit that's in turn damaging the F1 tyres I don't know. It cannot in my opinion however be simply a coincedence.
The other explanation (I tweeted during the race) is something we have seen teams do in the past and that's run outside of the parameters set by Pirelli. Camber and Tyre pressure is something the teams will always try to find advantages from and has caught out the likes of Red Bull in the past (Spa)
The quick fix for Pirelli will be to return to the bonding process used before Silverstone which allowed drivers sustaining cuts/damage to their tyres to return to the pits with their cars unscathed. The long fix is something that was debated during #TyreGate and that's the problem of no in-season testing. Changing the construction will lead to an advantage swinging in one teams favour, something I think we can ill afford at this stage in the Championship.
