They may say KD
W, but with that tread style their wet weather handling will suffer. I also expect them to wear a little quicker then the stock KDW's.
Like stated dry weather handling should be outstanding.
For reference - the normal KDW's have a new tread pattern that is definitely more aggresive and should provide both better dry & wet weather handling then before.
Still probably give their typical tread life though (300 rating my butt
)
