Prior to this tire, I had Continental ContisportContacts. Those tires were getting to the wear indicators but I didn't notice any drop in performance. I had excellent, very crisp feel with those tires. I have Bilstein Sport shocks & struts and H&R Sport springs. The ContisportContacts are a very good tire for on Bilstein Sports.
Moving to the V12 K110's, it was immediately obvious that responsiveness was not as good. This gave the handling characteristics a rubbery feeling. Transitioning in turns really brings out this negative characteristic for this tire, in this size, on this suspension.
That said, the overall dry grip is very good. Wet grip is completely acceptable, but I definitely could feel some hydroplaning in heavy rain. They are more comfortable and much quieter than the Conti's (I don't recall how comfortable/quiet the Conti's were when new).
Due to the rubbery response I now have, I won't get these tires again. Other than that, the price was great, they have great traction, and they're comfortable and quiet.
