don't know how serious you are about snow/ice but i put on hankook ipike studded snows during the winter, if the snow is lower than the bumper i have no problem except avoiding all the suvs with 20" rims and street tires that slid into the curbs.
discount should just replace your tires and then deal with continental themselves. this is what my shop does and we sell way less tires than dt. similar to buying a bad part from napa or milk from the grocery store. it's their responsibility to stand behind the products they sell, they aren't going to call dorman or the dairy to see if you get a new one. i would take my money somewhere else.
