I am awaiting my new X5 with 19" wheels sport package. When I go to tirerack and see upgrading tires only. When you enter in the year 2007, 4.8 sport it states that OEM is 20" wheels. Mine I am pretty sure is coming from the factory with 19" rims.
Then when I select upgrade 19" tires it gives the option to put larger tires on the back (285/45-19)and smaller ones on the front (255/50-19 ). What is the advantage of doing this over having the same size on all four 19" rims. Will my car come with the same size tires on all 4 rims, or will it come with larger tires on the back rims??
Sorry for my ignorance, I am just trying to learn what I can do with my new car.
