My Ride: 2004 545i Automatic - Premium - 19" M166 - Logic 7 - No Nav
Hi,
My car came oem 225-50-17 all around. I want to install a narrower tire (winter purpose), such as 215-55-16 all around. With my software calculations, the 215-55-17 will be 1.8% larger, wich is 0.4inch larger
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
225/50-17 4.4in 12.9in 25.9in 81.2in 780 0.0%
215/55-17 4.7in 13.2in 26.3in 82.7in 767 1.8%
Can I go ahead or would this cause major problem with the electronics ?
Thanks

BMW don't list a width lower than 225mm but it'll be fine as long as you're careful! (But if it's snowy...)

This tire calculator recommends staying within 3% of your stock tire height. So it should be no problem.
