Car rentals at Smithers Airport

Our Major concern and complaint is the quality of tires on the unit we rented. We rented a Toyota Tundra pickup for our visit in Kitimat, BC. The tires were the poorest quality for the current season for winter driving. They were bald tires (little to no tread). We picked up the unit at the Terrace airport and had to drive to Kitimat, while in Kitimat a major snowstorm hit and in 4 wheel drive we barely made it back to the Terrace airport. Our departure flight was canceled because of the snowstorm so we had to go back to Kitimat. On the return drive to Kitimat we were going down a hill and went into several skids and almost went off the road down an embankment (no guard rails and a few 100 foot drop). This is unacceptable to have such poor quality of tires on a unit for winter driving conditions. I am an experienced driver ( Class 1 license) for over 40 years. My experienced driving most likely prevented a serious accident. We had the good fortune of not having any oncoming traffic when we were in the skids. After such a harrowing experience I believe full compensation should be in store for us. And, Do you not have someone checking the quality of tires on units?
