I wouldn't say these tires are bad, there are some people running DWS 06 on our cars.

Here's a video of this guy running those tires (Description)
9:45 and 11:30 you can see this guy playing around with it
People here also run the same tires and have no issues (370Z, Camaros, Mustangs) all RWD there's also a lot of construction here in our area as well.
I saw someone else in this thread say they had the same problem, but also he/she has 2 different tires on the car, you should try running a set of 4 and let us know if you have any more problems hopefully it'll change your mind.
