Motor sport director Pierre Dupasquier, 67, told us that Bibendum make 'absolutely no compromise' in designing a safe design.
The Frenchman added: "When a product is due to be used on a vehicle driven by a human being, all internal criteria of security have certainly been passed successfully with no exception."
Dupasquier did make a distinction for 'racing criteria' like 'wear or blistering.'
He also revealed that Sauber's Felipe Massa incurred a similar problem at the German circuit last Sunday.
"(Felipe's) problem was the consequence of an excess of wear and a flat spot," Pierre Dupasquier explained, "and the technical staff of Sauber ... have agreed (with) that."
