Does anyone know if there is anything special required when balancing the tire/rim??? To make long story short, I had a nail in the left rear which was pulled out only after the tire guyS took 15 minutes or so to bust the tire off the rim. I hadn't seen a tire so mis-comformed/contorted during this process. Anyhow, there balanced job was no good. I took it another store that I trust and they fixed the problem, but I have slight vibration above 65-70MPH. So if there is something special with balancing, please advise. Of course the tire store could have goofed up the tire ever so slightly and I need a new left rear tire. Ouch. Thanks
