I was going to pick up some used tires off of some people on the forum, but I found a buddy who works at just tires. These will be some all season tires. Which ones should I pick up? Im looking for some decent mid range priced tires. Also, I remember being told to stay away form the stock size and get an inch (or so I think) smaller in wall size. Anyone what im talking about/what size that is? What tire(s) do you suggest?
