This is in the August 2017 print issue of Car & Driver:
The new Continental ExtremeContact Sport (which replaces the now-NLA Conti DW) did very well, placing second behind the Michelin Pilot Sport 4 S, with the Conti having a noticeable advantage in the wet.
Shame that none of these are available in 225-55-16 size for stock E500E wheels. For that matter, no major name-brand mfr offers "summer" performance tires in that size; only all-season tires. Conti DW was the last I knew of and it went the way of the dodo early this year.
