2) dynamic wheel balanacing is great for 98%+ of the time but once in a while there is a wheel/tire combination that cannot be balanced that way. The Hunter GSP9700 is currently the only 'balancing' system that can do "Road Force" and "Runout" analysis (check the link below for a recent discussion and the archives). You may have one of those combinations. Try moving the wheels left/right and front/back to isolate the culprit or, if no change, determine it is the steering/suspension that is the problem.

Please guys, tell me anything about this...
I bought 4 BRAND NEW rims, and 4 brand new tires 225/50/16
installed, balanced, everything all right . in a couple of weeks later the car started shaking a little bit... each day more and more, so last week i was going nuts. there are like 3 months that i dont know what does a "BMW MOMENT" means, i'm driving a piece of junk ! so i went to rebalance, and the machine was showing OO and 00 , cool ... but when they put the rims back and i started driving i was even WORST !!! my gosh, how come ? so i figure... it's gotta be the tires, they are not a good one i bought it from pepboys , so i went there and i fight, so they gave me 4 BRAND NEW tires, new models, the same size.. went to the best place around to install and balance. the car is a little bit better, but STILL SOOOOO BAD, it seems like the steering wheel and the back, the whole car is gonna fly... and the funny thing, one day it's sooo bad, the other is not so bad, the other i dont feel anything . i was thinking about two chioces, One the rims are busted .. (it can't be! i never hit anything ...) CAN IT BE THAT SMALL PIECE OF NYLON, ROUND, THAT GOES BETWEEN THE RIM AND THE CAR?? it didnt come with my rims.... what else can it be??
got new shocks (4) , new control arms, mounts, everything that makes the car shake was replaced . Please help me i'm going crazy!!! my rims are just like doug's :
