This along with the sharpie of a kerb in Silverstone added up for too much.
After that the tires were changed, but Pirelli also took more control over tire pressures, camber angles and usage of the tires.
So its not something Pirelli was forced to do. They easily could have said we aren't changing the tires and you need to deal with it by using our guidelines. Like you said they did start making sure teams are using their recommended guidelines but they also changed to a construction that's less likely to disintegrate if its punctured. I'd like to know if every tire that failed was used backwards on the car at some point. At the beginning of the season I thought I read something about the new 2013 tires not being directional anyway?
