I drove my 04 330 with the 18" rims and tires for 4 years in Alaska snow and never ONCE did I have any problem whats-so-ever! Went to the ski slopes mant times, on trips 4 hours away thru snow/blizzards whatever AK had to offer. The AWD-RX is a Solid car in the snow,
wwest has been negative towards the RX since day one--just skip his post and move on:) You have a great car and just throw on some nice tiresm you will be fine,
