Yesterday Raining, Today Graining
If Wednesday was all about the rain, Thursday was all about the grain. Graining occurs when the tyre slides across the surface and small ridges and tears form on the surface of the rubber.
Many had predicted tyre issues owing to a new track surface and the cool ambient temperatures prior to the event. These factors, coupled with a circuit with long straights punctuated by slow corners meant many teams did indeed end up suffering in FP2. And we were not immune. It will likely be a feature of the rest of the weekend, too.
