When I was looking at the duratracs, the CT website said 218 per tire, installation included, balancing extra. Whatever. When I got there, buddy at the counter tries telling me they're 345 a tire!! I said no no no, look on your site, they're listed at 218 each in the 33x12.5 size. Turns out I was right. I only had to wait 1 day I guess they had some in the local warehouse.
Maybe they are more expensive in BC than Ontario. Our winters are a bitch and I've already tried them out on snow/ice covered trails and they're great.
