I have one 4 year old XZE255/80r22.5 on the front left of my Journey and five 10 year old XRV255/80r22.5 with serious cracks and almost worn out at 75,000 miles. The deepest crack is at the age label "2303" is .100" deep and a nickle easily sticks into the the crack. Michelin states if cracks are over .062" deep the tires should be replaced. Based on reading this forum I will buy five new XZE's. Thanks for all the input.
