Seems like a lot of common problems with the Firestone tires (quick wear) on
Saturns over the last few years.  I've only got 25,000 miles on mine and
alot of wear.  More importantly, I've got more road noise that increases
with the car speed and what feels like a tire balance problem when you get
up to 70-75 miles per hour (vibrating steering wheel).  I've rotated the
tires a couple of times, but no improvement.  While the tires have alot of
wear, it's pretty even.  I've never had a tire balance problem this early in
the cars life (low mileage).  Have any other late model Saturn owners
experienced this noise and vibration issue?  Any luck in getting any work of
this nature done under warranty.
