full sized spare

[Eliot Lim <eliot@lanmola.engr.washington.edu>]

my p600s are on their last legs.. i figured i'd save one of them to
become a full sized spare... after all the well in the trunk was made
for a full sized spare.  the trick now is to get a steel wheel that
would do the job for as little bux as possible.  the 15X7 steel wheels
for the V8 are hard to find and cost $128 at the dealer... anybody
know of the existence of cheap 6.5 inch steel wheels?  can i use a
215/60 tire on a 15X6 wheel?  strictly as a spare of course.

thanks
