looks like some early problems with the Toyo RR - something about having to be mounted a special way and even then tread delamination ala early Kumho V710s. Will post more when I see more than just random forum posts here & there. Seen enough stuff from 944-Spec users and people like Phil (of Phil's tire) to think it's an issue with the tire and not an issue with the early adopters though that's for sure.
