Mine were dated March of 2015. Started to show very small cracks at edge of tread blocks. Got new in Late Dec. Put on the Nexxan with higher capacity. Just got back from another NC trip, all good.
Like anyone else, hated to replace tires with that much tread but 1st sign of dry rot or stress crack is time to replace. Was 36k miles, looked like tread good for another40k.
Brought old ones home and gave to buddy who will use on trailer.
