Yes, you can drive daily on the CN36s wet, dry. The tread pattern on the RA-1 doesn't like wet very well. It would be interesting to know the treadwear rating on the CN36s. This for the 13" versions...
From what I've seen:
RA-1 100 AA A, (Treadwear, Traction, Temp), not available in 13"
Michelin XDX-B 185/70 13: 100 A A
Vredstein 185/70 13: 160 A B
Kumho: 185/70 13: 700 A B
Laufenn 500 A A
Pirelli CN36 185/70 13: ???
Michelin XAS 165/80 13: ???
