Flat Tire

Came home last night and thought that the car felt like it was riding a little rough, so i checked the tires and sure enough I had a flat tire on the rear passenger side. I was a little worried that I had been driving on it for a while and that the tires sidewall would have been ruined. So I filled it up this morning and to my surprise it held. Drove it to Schwabs and had them find out what was goin on, and I guess the problem was a nail. the really really great part about Schwabs though is that if you bought your tires from them (like me) then stuff like this and rotating your tires is free. And that is a really nice feeling. So needless to say I'm "On the road again"
