By now, my five-season-old Hakka-1 (not 10) tires appear to have lost
about 50% of their studs, although there is still at _least_ 50-60%
of the tread-depth remaining. The stud loss started to be noticable
after the second season, which included a Winter Driving School
(possibly some overexuberance on the skid-pad). However additional
losses were noted in subsequent seasons of normal driving. These are
regular studs (not the Haka "Eco" type).

In some of my tires, there are gaps of 8 to 10 studs (in a row)
missing in various places. I cannot see much of a pattern to the
loss, although on one tire there is clearly more lost from the inner
tread than the outer. So far, this hasn't resulted in any noticable
imbalance effects.
