[s-cars] Snow tire problem

[Keith Maddock]

S-heads,

Yesterday I noticed a big bubble in the sidewall of one of my Dunlop
Graspic snow tires on the S6 Avant.     FWIW they are mounted on the
16x8" UrS4 factory 5 spoke wheels.  The tires are a few seasons old,
but without a lot of use so the tread is still pretty good.

Rats - I hadn't really planned on spending $$$ on a new set of snow
tires for the S6 this winter!

So a couple of questions - 

1) Anyone have a used 225/50/R16 snow tire (or 2 or 4) with at least
1/2 tread ?  ( to get me through 1 more month of snow)

2) Any opinions on putting 205/55 R16 tires on the 16x8" rims?
Everything I've read so far says the 8" rim width is too wide.

3) TIre-rack replacement set seems to be the Blizzak LM-22's, at $608
shipped (ouch!!)  Any BTDT on these LM-22's ?

Cheers,
Keith
