With rotating back unmount flip and remount on opposite side I got a scosh more miles out of gmax than I did dsw and dsw 06.
In gmax I ran 275/35 and with the dsw and dsw06 285/35.
I think the Gmax did a hair better in rain than the continentals, the Continentals I think have better dry traction, both have surprised me in winter, I use extra weight in winter if there is a chance for slick roads.
Without rotating the gmax, they will not last as long as the continentals, and can not rotate the continentals.
