Contenental ExtremeContact DWS06+ I did the stock 275/45/21
I've run several sets of these on multiple vehicles and love them. Quiet, good traction and were decent in the snow. I just passed 20K miles on them and wear has been even. I still have the visible "S" on the tread depth indicator (meaning still good for snow) which means there is at least 6/32' of tread still left. I think 10/32' is new, so almost to the halfway point on these tires
