Well after many miles on the Nitto Durras (45k+) I thought I'd try the new Nitto CrossTek they seem to be a bit more highway/mild off road compared to Durras more hwy. Don't get me wrong my Durras were great but were a bit stiff which I understand 285/70/17 E rated load per tire 3970 Durras. CrossTek 3179 so hope for little smoother ride I hope. Nitto Techs said I'd get a little less life on these then durras but were surprised I got what I did on my Durras for my driving. So we'll see what life brings.
