I just bought a 128i with Sport package - summer tires. I live in Maryland so consider all-season M&S tires a good compromise for me. Eventually those would supersede the run-flat OEMs when the latter are worn out, until then swap out spring and fall. Do you think this makes sense, rather than buy new wheels?
I note from earlier posts that some replace their tires on the sport package (different tire size front and back) with same size tires all around. Will this induce oversteer or other handling issues? Said another way, one thread said that BMW puts the wider tires on back to induce understeer. True?
Any perspective would be most appreciated.
