Thanks for your suggestions. I have all my paper work lined up, and in order from the previous trips to the dealership. As far as road conditions = snowy roads hence the use of 4 wheel. This is the 5th four wheel drive vehicle that I have owned or use fairly regularly so am very familiar with it applications. As far as tires they are all BF Goodrich All-Terrain TA-KO 245/70 R16 and all the same age so between rotation and mileage they are worn virtually the same. As far as this being a safety feature, it is the worst damn one I have come across, it is down right dangerous. Thanks again.
