First of all, you should not be running 3 different tires on the car.

At minimum, you should be running the same two tires on the front, and the same two tires on the rear.

All rims are not perfectly balanced or round, and the tire balancing process takes this into consideration.

However, if your wheel is too out of round, the only machine that has a chance at balancing it is the Hunter GSP9700.

Go to the website, enter your zip code, and it will give you a list of shops that use this machine:
