[s-cars] Tire size for '01 A4

[Mark R]

Automotive suspension 101:
All things equal (design, spring rates, etc.), ride quality is the ratio of
sprung and unsprung weight.  All things equal, the heavier the car (or
lighter the axle weight), the better the ride.  Of course, low unsprung
weight has a lot of other advantages in maintaining tire contact patches and
with any transitional weight transfer.

Of course, the Audi multi-link suspension design is one of the best for a
variety of reasons.
Lighter wheels don't HAVE to break the bank on an Audi.  On my Corvette
Z06....well... open up the checkbook.  =)

Want to make a car faster AND handle better?  Add lightness.
