Volume of air in a cross section of a 225/45/17 is gonna be about 22,700MM^2
Volume of air in a cross section of a 205/50/16 is gonna be about 21,000 MM^2

According to my door card, tirerack.com, and my fuel door, proper size on my car is 205/50/16.

Also, my car isn't lowered and isn't going to be, so thats a non-issue for me.

The part about chains is also a non-issue for me because 1) I run winter wheels with snow tires and 2) chains are illegal here anyway.

I don't have mud guards either, so thats also a non-issue for me.

Man, 17" and 18" wheels look awsome on 850's and S70's. Knock yourself out. Enjoy!

Im not even doing it for the look. The cost of wheels (which i was going to get anyway so I could have winter wheels and summer wheels) will be MORE than offset by the price at which I can get tires.

if it werent for the awesome deal I can get on tires, I'd be leaving the stock 16" wheels for summer tires and getting 15" wheels for winter.

Get the Volan's they look good!

Got my tires here last night. Ordered Titans this afternoon. Thanks for the input, everyone!
