I'm with you on the DWS in northern US climes as a year-round if you aren't swapping out for winter tires. Down south, I'm with TiAGX5, the DW Conti would be a better choice. Of course, I'm weird enough to have DWS mounted on my X5's original wheels for 'winter' use in North Georgia, where we have rare but nasty ice storms, with summer high performance Coopers [Zeon Xstas] mounted on brand-new 209 wheels I got as a bargain off of a 2013 E70 ....... For summer use, I like the Coopers, the DWS seemed soft and mushy in GA summer heat.
