If you cannot afford any Blizzacks then I would buy two 60-lb sand tubes from the Home Depot and put them in the trunk This saved the 350Z I once owned. Once I purchased the 4 Blizzacks all-snow tire I didn't need the sand tubes any more.
My 370Z is a garage queen and I now drive a 1999 Grand Am beater as my 240 mile round-trip / day work commuter. Even with it I bought 4 all-snow tires so that I don't end up losing the beater and having to drive the 370Z. It never seems to end doesn't it?
