On car balancing is not needed for the Delorean. As long as everything is normal spin balancing the tires on a modern balancing machine is just fine besides your mechanic is correct if you attempt to spin balance the rear tires on the car you risk damaging the final drive if a 5-speed and on an automatic you can also cause damage to the transmission. Modern tires are now balanced very well. Make sure the mechanic lines up the tire index mark with the valve and you use the minimum weight to dynamicaly balance the wheel-tire assembly. It is also better to balance the tire off the car because if you ever remove the tire you MUST put it back on EXACTLY in the same position or you will throw the rotating assembly out of balance!
