RE: Hakka CS
The Nokian Hakka CS is a Load Range D tire.
I'm running them year round (185R14s) on my '90 Westy that comes in around
5,000 lbs plus when I'm traveling and find them very stable at any speed and
probably more stable than the Agilis I was running for several years before
that.  My wear has been great, no excess wear that I'm seeing.  The Hakka CQ
is supposed to have a softer compound and not get as good a mileage as
reported by several users.  But the CQ is rated as an ice tire.  I'm totally
happy with the choice of the CS.  Only negative is increased road noise over
the Agilis I had been running but the Agilis were virtually silent so any
noise would be noticed.
