Generally, I think buying used tires is a bad investment. Especially right before Winter when what you really need is some nice new tread. The exception to that is if you can find a set of 'take-offs' where someone bought a new car and wanted something different. I'm on the CX-30 forum and a lot of people seem to dislike the Bridgestone Turanza they come with and change out right away. Others have no issue with them. I thought they did great so far in wet. Geuss I will find out soon for snow. Can't imagine it being an issue for me coming from a FWD Neon running Hankooks. LOL
