I was treated to a flat tire this morning, a slow leak that finally flattened one of my rear Bridgestone Potenza PP S-02s (255/40/17) that resides on a Breyton Inspiration wheel (I have all four, but just one had a flat). I took my handy electric pump and air'd it up to 35PSI and limped to my local National Tire & Battery (NTB) and had them check it out. They fixed the small, innocuous, middle of the tread puncture (damn nail), balanced the wheel, remounted the wheel using a hand torque wrench, wiped the wheel clean, and charged me...
I didn't even buy the tires there, but they didn't care. I was impressed, to say the least. Total time in and out: 28 minutes.
