This is the first set of the Copper tires that I had put on the car after OEM tires wore out (32K). I have been very impressed with all aspects of the tire, but most of all the wear. Of course, I always check to make sure the tires are properly inflated and are rotated according to the specifications (6K). I now have 91K on them and they are at 7/32 in depth. Should be good to go for another winter in Michigan. When they finally do wear out, I will not hesitate to install the tires again. I paid $408 for all four mounted and balanced with a 3 year repair replacement warranty.
