the heavier the wheel/tire the harder it is to shake the shimmey, 15s and 16s are fairly easy to get to run true but bigger then that and the weight is harder to control, stiff thick sidewalls and bigger rims gets the mass farther from the hub, and that shows the flaw in the suspension design, if you think a e34 shimmeys you outta check out a e38 with 19"s, you'd think the car was coming off the ground

yah i had that explained today with my huge lipped Rondells. I could tell he felt while they may look good they aren't a great design from a technical perspective . I am being very strict about what i think i'm feeling maybe most people would just consider it " normal" and not even think it something you could or should worry about but i know the thing can run with an absolutly solid, smooth, quiet ride where even the most violent road conditions are defated absolutley and induce no persistant infirmity for a driver to feel once over them . In other words if i can feel the steering wheel even sligjhtly shake even on very smooth pavement at 55 mph i have to believe something can still be tuned and the rims are beginning to appear the likley culprit even thogh so far all the diagnostics come back as "accapetable" . I've tasted perfection before in this thing so I know its possible..
