Tire vibration / thumpping issue at track
All,
Went and did a casual track day at MSR in Cresson, TX and very quickly noticed something developing on my Boxster S.
Running R888's and I felt a vibration and heard a thumping coming from the
right front tire. This only happened during right corners, when the right tire
in normally unloaded. During left had corners, there was no noise. I looked at
the tire itself and saw that the outside edge was down to slick and the inside
edge still has some of the grooves left. This got progressively worse as I ran
sessions, and to note, there was some tread at that outside edge at the
beginning of the day. I am wondering if the uneven tire wear was contributing
to the vibration / noise. Another PCA / Boxster guy happened to be there
and as I described the issue to him, he thought wheel bearing, but I am not
sure... Any thoughts?
