255/70/18 Falken Wildpeak ATW3 weigh 1lb more than the same Duratrac Kevlar....so I don't see the weight savings on my Jeep. I'm thinking you are comparing the higher load rating Wildpeak compared to the Duratrac Kevlar. All things equal tires weigh almost the same.Lot of Wildpeak owners and almost all love them. My concern is the extra weight, only light tire with a strong sidewall is the Duratrac with Kevlar. I've looked at KO2's and it the weight again. The Kevlar Duratrac's would save almost 40-50 pounds in rotating weight depending on size.
