Since years
I think these tires are misunderstood and reviewed poorly..
The first year I learned these tires need special attention. Aggressive driving in the dry will wear these tires rapidly (Saved them by rotating and letting the wear catch up). Also they have 6ply constuction so load ratings are different - so like big 4x4 tires the inflation needed to be reduced - which if not adhered to will wear them out super rapidly! Mine wore evenly 10-15psi less than the manufacturer recomended psi without affecting fuel economy.
I had great experience with these and would recomend them to everyone with an SUV who is not going to drive like they stole it. I think of them as Winter tires that work safely in the summer wet or dry but will fail quickly for high performance summer use.
Cant have everything.
