Get that on the front of a twitchy little sedam like a BMW320 with
only a static ballance, and your hands will get a good massage from
the steering wheel, even if the bumper doesn't jump.

I fully and completely understand.
But, at least in my ONE (single!) test of 5 tires on 5 rims, it didn't happen.
