No spare wheel or run flats? WHAT?
Just discovered that the M5 doesn't use run flat tires and doesn't seem to have an option for a spare wheel...WTF?
Am I missing something? What do you guys do on long road trips or when driving through desolate places and have a blow-out?
Can a spare wheel (even if a thin one) be fitted to an M5? Or can run-flat tires be used?
