I'm coming close to needing new tires on my 05 M3 and have always been uncomfortable with that M Mobility kit, was contemplating the compact spare that you can order and store in the trunk (there's goes my trunk space), but also wanted to consider run-flat tires since the M3s have the necessary pressure monitoring system needed to use run-flats.
Any suggestions/experiences with certain brands/etc?
