Call me a slob if you want, but I'm usually happy to get radial runout on my "experienced" wheels less than 1 mm or so. And yet strangely enough, most of the bone-jarring vibration I experience with such terribly crude wheels seems to show up on old, rough pavement -- the kind of road that would benefit if public works would come put a coat of tar and gravel on it.
0.05 mm? How's that compare to the thickness of a playing card?
