I am using the V2 Concept 2 rubber now at 215/45R17, previously using Silverstone M5. I have clocked about 20k km on this V2 Concept 2 since last year purchase.
My personal comment
1. Dry grip - 6/10
2. Steering response on dry - 7/10
3. Wet grip - 7/10
4. Steering response on wet - 6/10
5. Noise level - 5/10
6. Side wall stiffness - 7/10
7. Comfort - 5/10
8. Wear - about 70% remain after 20k km used
This tyre is not up to Michxlin PS3, but definitely better than the XM2. It also above the BS Ecopia200, Txyo C1S and T1S, comparable to Cxnti MC5.
This is UHP tire but it provides reasonable comfort meanwhile good grip at all weathers. Compare to V12 Evo, it is more comfort and less noise but grip of V12 is simply greatest among Hankoxk.
