Is the heavy point on the outside of the tire or on the inside. This difference can often be the problem where you have a tire/wheel in perfect static balance and yet have a wobble or vibration in your steering wheel. This is where the dynamic balance requirement comes in. Now it gets complicated. I have not done it(but now I guess I will), but I suspect that a Google(again) search will give you more information then your brain cells would wish to absorb on this topic. Static or rotating staic balancing may well be acceptable to certain drivers. Dynamic balancing is accomplished in two parallel vertical planes spaced as far apart as possible. This procedure takes the wobble forces out. Suggest check out Hunter Engineering and road force variation tire balancing (Google search). Proper use of the equipment involves tire indexing. This procedure I would think would be better, more time expediant, than attempting to find low and high spots etc. by some other trial and error method Goodyear tire store here in Sedona has such equipment so some tire store in a metro area should also have the Hunter stuff. Best true running tire/wheel asemblies we see have alloy wheels which are machined round and true as opposed to stamped wheels which can have an incredible amount of runout. How does NASCAR run 190+ on stamped steel wheels; seriously, how does that work? Balancing in two planes at the wheel outer edges will minimize the weight required. Tape weights on the inside of the wheel will provide only rotating static balance which may be OK and they can run into things and not stick real well. A large tonage of tape weights may be required also (short moment arm off the wheel center). As an extreme case, our Hummer customer has some very nice looking alloys on his H1 's but there are no clamp on weights available so we are forced to glue/pile (big) lead tape weights inside the wheels. The Mickey Thompson tires he runs need a lot of balance weight compensation even with the nice alloys and there are still dynamic imbalance problems and the tires have a lot of runout.. There was a shop near here that was dynamically balancing off the car and then spin balancing on the car which was reported very satisfactory. This will not make lumpy tires run smooth.
