I know I'm not confused - I meant just what I typed - the plural of DW (DW's - since there are 4 of them).
I have staggered Conti DW setup, so far I've gone thru (2) sets of rear tires to (1) set of fronts (and NOT due to uneven wear - they wore evenly across to slicks). And I got less than 20K out of a set of rear tires.
The fronts are between 20 & 30K and are OK in middle & outer edge - worn down on inside edge.
They are excellent handling tires - but they sure didn't last near the average as stated above - and this is on a NA 328iX, so there sure ain't no big power here...
