I have also recently purchased new tires for my DeLorean (they only have about 300 miles on them). Unfortunately, I still have the vibration problem. I know that it must be due to an imbalance because the vibration is extremely repetitive and its frequency is almost perfect at a given speed. I am very interested in trying one of the "on car" balancing methods.
