Why are these tires so cheap?

Cooper/Mastercraft tires are a mixed bag. I've had good ones and bad ones. The AT tires I had by them a number of years ago were great at first and down right scary on wet roads a few years later. They no longer make that model. Their all season and winter tires were fine. I've never used their mud tires. Jim seems to like them.

My Cooper AT3's are a little more than halfway worn down and were totally useless in the first snow of the year we got yesterday. Great in snow when they were new. I'll try and dance through the next six weeks of snow season. Thank God for global warming.
