I don't see any R compount tires on the website anymore. When it was there it was marketed as a specific forumation to address durability issues on hard-packed blue groove tracks. Soft as an M3 but supposed to last longer. I could never really find any more info beyond that, nothing specifically stating where on a continuum for both durability and traction it fit with respect to the M2 and M3 compounds...other than that information implying R3>M3 for durability. But I don't know where it stacked up agianst M2. I've heard people say it is actually less durable than M3 though, along the lines of what OTE said.
