Since Getting my Konig Hypergrams installed on my car with the OEM tires I have noticed considerable vibration coming through the pedal, steering wheel and even the seat a little. Have not had a chance to swing by discount tire to have the look at it, but what could be causing this? Tires not getting balanced? Installed wrong, if you can install a tire and wheel wrong and still be able to drive. Never had any issues like this with OEM wheels using same tire.
