I have a 2011 335i xdrive with sport package that has 17" all-season Contis. I will see how the tires perform in the NE Ohio winters. Should the all-seasons fail I will get Dunlop dedicated snows which means I will need to get summer wheels and tires. I am thinking about an 18" staggered set up but I would like ideas as to what wheels and tires some owners have on their 2011 335's or what combination would work. I would like to get OEM wheels and it doesn't matter to me if the tires are RFT or conventional. I am open to a 19" set up if you feel that would help the car's handling and ride. Any ideas?
