So, do you have winter rims and you just need the tires installed or you need your current tires removed from your stock rims and the winters mounted and balanced? Any shop should be able to handle this task, which ever it is you are doing. Have you inquired at an Active Green & Ross or any other shop? Even CTC can do that.

If it is just mounting the tires on the rims you can do the swap in your driveway. But that is assuming that you have a set of rims just for the winter.
