Which Tires and rims to choose?

[tekman]

Ok, so I've already ordered a new F25, Black on Black, Aluminum trim, Sport Package, Premium and Cold weather package.

I'm uncertain if I should update the order and get the sports tires and rims for only $600 more. It seems like a decent upgrade for the price, and it makes the SAV look much more sporty, however I have one problem.

When I take delivery it will still be winter, and although we don't get a ton of snow here in the St. Louis area, we do get some and we do get Ice storms occasionally. With the sports performance tires I know I would need dedicated Cold weather tires right away and put the performance tires up for the remainder of the winter.

That being said, are the performace rims and tires in the upgrade option, that much better than the normal tires and rims?

Also,

Is it a smarter option to just get the dedicated 18's and Spider style rims that are defaulted and use them for normal cold weather driving, then get a custom set of summer sport rims and tires later in the year for summer driving? Again, I'm not really knowledgable on what after market RIM and tire options will fit the new X3 yet.

Thanks in advance.
