Editorial Comment:
In theory there really isn't too much or too little weight to correctly balance a tire. The idea is to simply add sufficient weight to compensate for the irregularities between the tire and the wheel combination.

In practice, however, this could become ridiculous and a technician will start to wonder if there are some defects in either the tire or the wheel if you go beyond a certain "normal" weight range.

I haven't heard of any standards that are established, and it sometimes is affected by the size of the wheel -- larger tires use larger amounts of weight than smaller ones.

In my experience for a passenger car anything over 3 or 4 ounces seems to be excessive, but for a 19.5 inch tire, I would be concerned if the balancing required more than 5 or 6 ounces.
