    Well outside wear indicates an alignment problem so maybe they haven't done a very good job of that. Basically your tires are squatting outwards----tops of tires further to the outside than bottom of tires, looking straight ahead at the car's front end. So that's a "camber" issue.


    Once the tires are worn like this, you can't align them accurately, so it's kind of a moot point.

    But to your question---yes, putting the worn tires on the front is the proper decision. On the other hand, it's a compromise for safety over wear---since the tires on the front of a FWD vehicle will wear out more rapidly than those on the rear.

    So next year, when you replace the front tires, move the better back ones to the front, and put the new ones on the rear---and ask them to get the alignment better this time.

    I think that could be a tough call. From normal rotation standpoint it better (as you suggested) to get more even wear by rotating . On the other hand for winter I believe the idea is to put the best (newest, more tread , whatever you want to call it) tires on rear to prevent the sideways slippys.

    The tires with the most tread go on the rear, that way you won't spin out (front tires gripping while rears loose traction). But two things:
    1) If you're having tires swapped out twice a year, they should be alternating front to rear to keep wear even on both sets.
    2) If your tires are wearing unevenly I'd get the alignment checked, they should wear evenly across the tread.

    How uneven is the wear? You may want to get a tire tread gauge and measure it. If it's obvious to your eyes, the tires don't sound safe.

    Also, are you having the tires mounted on a single set of rims? That requres balancing every time. I found it much easier to have the tires put on separate sets of rims, makes changeover quick and cheap.

    "How uneven is the wear? You may want to get a tire tread gauge and measure it. If it's obvious to your eyes, the tires don't sound safe."

    The tires passed inspection, so the wear is presumably acceptable. The wear is even (we get the alignment done frequently... we paid for lifetime alignment at the tire shop).
