Hi, the front right tire of my civic has been leaking for this winter. The low tire pressure lights will be on about once a month, usually it happens when the temperature drops down. Beside the leaking problem, the tire is in good condition, I replaced it in 2011 with a Bridgestone tire. Do I need to replace this one or I only need to patch it? If I need to replace it, do I need to replace a pair or only itself. In 2011, the mechanic only replaced one tire, as all four tires are almost new. My car is 2009 civic. I guess the leaking is caused by my bad parallel parking habit, I might hit the curbs sometimes. Thanks a lot for your suggestions.
