Please avoid CC5, I used CC5 before for 8 months, and I would say it's not a safe tyre, especially on wet roads. The only good thing about CC5 is quietness, they are really really quiet tyres. Wet grip is bad for CC5, especially during corner on wet roads. If you insist to use CC5, please make sure u make every cornering (on wet road) at speed lower than 35km/h.

Im using 13" tyre, so I changed to michelin XM1 (because XM2 doesn't have R13 size). Feel much safer now.
