[BiturboS4] S-03 tire noise and vibration

[Marc A. Abernethy]

I run with a high tire pressure 41-42 psi.  I carry a ton of crap in my trunk and
back seat.  This is what was suggested in the manual.  42k miles on my original
P6000 with no uneven tire wear.  I have a lot of bump steer as well.  I think
that is because of the stiff side wall, high pressure and weight.

I guess I can deal with the noise but it seems weird that there is so much
vibration also.  Are you guys getting the "cupping" also?  Run your hand over the
outer edge of the tire.  Does it feel cupped in some places?

Also, I was winding it out today and smelled a burn oil smell.  I figured that
can't be good.

While I am bitching.   Audi, listen up.  The Bose stereo sucks!!!!!  Sorry, I had
the windows down and stereo up today.  All I could hear was the sloppy base and
rattling trunk.
