I recently bought a set of Nankang tires (215-35-18), and they have given me nothing but trouble. I have had about eight flat tires since August. I have also bought two more tires since then. One is a different brand only because I was on vacation when had to buy it to get home. That one tire hasn't given me trouble unlike the other three. Basically this is a suggestion for everyone not to buy Nankang tires, and a question to ask what a good tire is for that size. I drive my car a lot because of work, so I want something with a strong sidewall in case of potholes and something that will stick me to the curves.
