EBay is your friend in times like this.
Do a search for BMW E90 RIMS. You will get OEM and aftermarket hits. You can
narrow the search by specifying OEM and 17 INCH in your parameters. Since
you live in snow country, you might find that your tire store has less
costly steel rims to mount your snow tires on.
Well, if you can afford a second set of tires, and you need rims for them,
then the sky is the limit.
I found some very nice E36 rims for my '94 325i convertible that came from a
'95 M3 on eBay. I paid $600 for all five rims, put rubber on them, then wore
the rubber off of 4 of them and bought a new set, and the cost for all of
those tires (9) and rims (5) was less than 2 sets (8) of 15 inch tires for
the rims that came stock on the car.
I would think that since your car is new, maybe the rim availability might
be a bit slim for now, but there are always people out there that want to
replace stock rims with 18s or 19s, so you ought to be able to find a good
deal on a set of factory take-offs.
You might end up with a set of rims for your summer tires that are 18s, and
use the 17s that you have now for the snow tires.
I have never seen a car with snow tires on it. Sucks to be me ...
Jeff I told a friend that I am waiting for my new BMW and he said that
you have to let the car sit for 1 minute after you stop be for you
turn of the engine because the turbo will overheat and wear out
prematurely. I am waiting to hear back from BMW in this regard do you
have an opinion.

I'm pretty sure that the turbos on the E9x series are water cooled, and are
provided with an electric coolant pump to keep the coolant moving for a period
after shut down.
That said, it's prudent to go light on the throttle and avoid boost for the
last few miles to your destination - particularly if you've had an
"enthusiastic" drive ;-)
'00 s4 6spd - original biturbos still working perfectly
So, what if the last minute or so of travel was essentially at speeds just
above idle? For example, you get off of the interstate and drive on surface
streets where the turbo(s) would not be used -- similar conditions as idle,
excep the car is moving at moderate speeds -- and then you pull into the
parking lot. Would the 30-seconds after a run rule be satisfied, and could
you then shut the car down and walk away?
I get that one would want to avoid trips where the turbo was kicking in, and
then pull over and shut the car off without a cool-down period, but it seems
to me that if 30 seconds of idle is all the cool-down that's required then
surface street driving -- or any driving that does not invoke the turbo --
would satisfy the need.
I have never heard of this rule, by the way.
I'm almost 100% certain that if one is concerned that the turbo charger
needs to be protected from heat damage by waiting for it to cool down before
shutting the engine off, then the oil is at operating temperature -- or the
turbo is operating at conditions that would harm it anyhow, and waiting for
it to cool off before shutting the engine is the least of the things the
driver would care about.
