Run flats

Post by bonzo » Tue May 18, 2021 2:59 pm

I'm not a million miles away from having to replace my tyres so would like to know if run flats are OK on the G29.

Has anyone fitted run flats? Are they 'recommended' by BMW?

I thought run flats were standard?

Unless your alloys are RFT specific then you can't fit runflats. The other way around is possible where you fit ordinary Tyres to RFT alloys but not vice versa.

Run flats

I had run flats on my 4 Gran Coupe, the road noise was horrible.
The Z4 generates less road noise compared to the gran coupe, I get a little more noise from other vehicles now (not that much), but its less annoying then the sound of run flat tires :)
I feel like run flat tires are also a lot harder compared to normal tires, not that it bothered me that much, but the difference now is very noticeable even with the harder suspension the shock absorption seems a lot better :)
I also only had one flat tire in my life (I will most likely get 4 flat tires tomorrow now). So the discomfort is not worth it to me. If I do get a flat tire there's BMW assistance. :)
I also think if you want to go from non run flat to run flat tires you have to change the rims.

Not on G29’s all cars run Michelin’s with a tyre repair kit :thumbsup:

Actually states run flats can’t be used on standard rims
