came across this vid on what I assume was an FD2R press day at Suzuka. It's in Japanese, so don't really understand what he is saying (the only words I recognise are "fun" and "fast").

Interesting shot of the tyre's tread pattern and how widely the pattern (and compound?) varies across it's width.
