I'm seriously looking at getting the 2005 330Ci. This will be a daily driver so, how does this car do in the snow with conventional all season tires? I really want opinions of people who drive this car year round. I could get blizzaks, but they would wear out in a month or two here in Denver. I don't really want the Xi, only because I'm not fond of 4 doors.
There are harder-wearing snow tires than blizzaks. I believe there's a Dunlop option on Tirerack that is supposed to give much higher mileage. I use Pilot Alpins, which are an M&S rated tire but are much closer to an all-season radial in terms of handling, but with more snow & ice grip and a much longer life than the Blizzaks.
With the DSC on, the Alpins work fine and can be run from December to, er, about now. They also have all-season level handling in the dry. However, I have to say that if it wasn't for the mileage issues, I would go for a more dedicated snow tire. I would echo the comment that DSC really works as long as you aren't trying something dumb, like running Advans (or any other summer tire) in a snowstorm. It's tendency to cut the throttle abruptly can be a pain in a light summer rain, but in snow it makes sense, and will generally let you have as much power as you have grip - at least that's my experience.
Because you're getting a 330, you will not be able to use steel wheels due to front brake rotor sizing (unless you can find 17" steelies), which means you will have to buy some sort of alloy wheel if you want any sort of dedicated snow tire. I got a very nice set of 17x7s for $109 per wheel, but it's still an "investment".
Note that the contisports that will probably come on your car are generally loathed, so if you decide to go the all-season route, I would suggest at least taking those off and/or selling them on e-bay and getting decent replacements.
