I recently had a set of Michelin Commander II s put on my Voyager and after 200 miles I am noticing quite a bit of steering "head shake" whenever I ride with a light grip. The front end also seems to understeer somewhat in corners and feels like it is skipping across pavement imperfections if I hit them while in a turn. Anyone else noticed this? I'm running the recommended 28 PSI. Is it a front wheel installation problem? The manual is very specific about torque values and spacer gaps. I'm taking it back to the dealer to have then check their work but wanted to check here first for any info you all may have.
