Ive never had this issue before until this winter. Im not going to fast, no warning lights come on, and my tire tread is adequate. However ive noticed when making turns (in snowy weather) my truck seems to almost always fishtail no matter what I do the back end loves to slide out. Anyone know what would cause this issue? Im quite confident its not due to driver error, I even fishtailed today when coming into my driveway. Thanks!
