Hi. I recently changed all 4 of my run flats with normal tires....anybody knows where I can get a donut for this car? I plan to just put it in the trunk if it fits. Else, I'll just leave it at home. I asked Ingress KD and they dont sell it. Thanks.
The kit is called a Mobility Kit and it cost around RM450-500 from BMW. Beware the sealant has a shelf life and it is more for minor repairs of punctures.
BMW does not stock the Mobility Kit anymore. You can use other car kits such as Hyundai's or KIA's or even Audi's for the non-RFT tires. Other option is to get tire repair kits such as Stop and Go or Dynaplug.
