I had my P3D tires rotated at Costco on Sunday. After it, I noticed when driving slow over some uneven surfaces at slow speed I would get a little vibration. At speed, everything felt normal. I just went back for them to check it out. Turns out both my front rims have slight bends. The good news is that it isn't a safety issue. Just bummed about those California potholes. I don't think I will replace the rims yet as it is a minor thing. Does anyone know how much the Performance rims cost each?
