I just wanted to make sure I didn't rub with the 40mm offset, a huge concern for me, that is why I chose that tire. There are also not many choices in the 215/40 size, HTR zII and S Drives are older designs and I didn't need a track/street tire, AD 08R, RT 615k, Spec Star, Federals, not to mention cost concerns. There for the best guess/move were the Kumhos...
