Like alot of people on here i am considering going for 19" upgrade (either CSL or E89 M Sport).
Currently i have 18" MV2 wheels with factory runflats.
I hear alot about Runflats ruining the ride and handling, well that's not a issue to me at all.
My worry is safety and in-connivence so want to know other people's thoughts and experiences please?

Obviously i currently have no spare wheel and have no need for one,
but if i ditch the RunFlat tires will i need Tyre Repair foam and is it actually any good? :|
What are the actual Pro's and Con's please?
 
You might not get a huge response here, as this has been done to death in various threads.

In summary, non run flats improve the ride, reduce tramlining, and skittish behaviour over bumps. On the down side you'll need a tin or two of tyre gunk and a compressor in the boot, to re inflate your tyre in the event of a puncture.

I've never heard regrets about moving to non run flats

As above - a quick search will show you lots of threads on this but the change to Non RFTs changes the behaviour and character of the Zed significantly for the better. I got myself a BMW spacesaver as opposed to the 'tyre gunk' - takes up space in the boot but still enough room for a long weekend aways clothing etc.
 
We are now running non-RFTs (Michelin Pilot Super Sports) on OEM 19" wheels with lowered suspension (Eibach Pro Kit) and the ride and handling is so much better than the original RFTs gave.

RFT :thumbsdown:

Non RFT :thumbsup:
 
I know the topic has been done to death but iv not heard much about realistic paticalities but loads about 'ride & handling' changes.

See i dont mind the ride, its a sporty roadster and i expect a firm ride.
I have driven a Z4 on aftermaket wheels and non-runflats and have to admit although it improves the ride its realisticly only by a very very tiny ammount, and there is still noticably tramlining. but i have had my Z4 nearly 18 months and i like the handling and ride.

I already have a compresser i kept from my previous car as I had a lot of issues with puntchures in the past (4 in one year & and i only drive 9000 miles a year).
Does 'tyre gunk' work very well?
Are all similar products as good or is there one particular brand thats better?

I just need the confidence first to make the swap instead of being stranded on the hardshoulder somewhere :|
 
ESP,

Its a matter of personal choice (and indeed driving style) and the change in ride depends on the tyre you choose to make the replacement - so a tiny amount you experienced may be related to not only the change but the tyre brand/quality. If you are happy with the RFTs, the reassurance they give you and the ride quality then perhaps best to stick with them. And as you say you like the handling and ride with your current set up.

As with tyre gunk choice a quick search will reveal numerous comments and recommendations but the water based ones are considered best as the residue can quickly be cleaned out to effect a repair (where a repair is possible).

Thanks Alan :thumbsup:
now off to search ebay
 
I bought a VW/Audi/Porsche tyre mobility kit off Ebay for only £25 or so.
It comes with a compressor that plugs into 12V socket and a bottle of sealant. I would suggest looking for a continetal mobility kit on Ebay.
 
For longer drives/ europe i would def invest in a 17" space saver just in case.

Everything else... thats why i have roadside recovery to anywhere in the UK... just get them to carry my car home.

:thumbsup: Cheer's for your help guys, it is a big help and these things are a nagging worry to me before i take the 'Leap of Faith' lol

Next question though, lol
What about the car's pressure sensors?
If i fit Other Wheel's (CSL's or Z4M wheels' with out runflats) will i constantly get a error or Low pressure reading??

EU cars use the ABS to detect the rotation speeds difference for wheels across the axle. So nope you'll have no probs with that running 19's and/ or non run flats :thumbsup:
