Interesting RunFlat B$

I did a bit of research on the internet on run-flats and the general consensus is that there is no risk in replacing run-flats with non-flats, EXCEPT for an emergency situation. In some countries the law seems to state that if you remove run-flats (which you are allowed to do), you either need to install a puncture repair kit in your car (or have a spare). However, from a tyre performance perspective there are no issues.

Anyway, with this in mind I spent some time visiting 3 tyre dealerships in Centurion (I won't mention the names, but they are all opposite one another) and I thought I'd share my experience. (BTW, my Mini is specced to take run flats, but I currently have non run flats on)

1) Dealer 1: The sales guy told me that the Mini rims (as with most new BMW rims) cannot take non run flats due to the lip design :bs:. We walked over to my car and showed him non flats on the Mini rim. After a long pause, he said that it is a safety risk and the tyres can slip off the rims during hard cornering :bs:. I mentioned to him that it's strange that this never happens on a track where non runflats are used with standard Mini rims and cars are pushed to their limits. He ended up quoting me on both run flats and non flats and said I should decide, but should at least have a puncture sealer can.

2) Dealer 2: Told me outright that it does not make a difference what tyres you put on the car. Only that if you go non run flats, then you need to consider a puncture sealer can or something in case of emergency. He also saw many cars come in with run flat tyres that had completely come off the wheel. Also, a run flat can be damaged to the point where you cannot drive the car - so you end up in the same situation as having non run flats.

3) Dealer 3: This was interesting. The guy told me that he would not fit non run flats on my Mini, unless I got a letter from my insurance for him. He was insistent on this and would not sell me a tyre otherwise :slap:


Anyway, just thought I'd share my experience on this and highlight some of the B$ floating around .... The problem is that I wonder how much of this B$ gets fed back to insurance companies to the point where they start refuting claims

Also, some of the run flats are becoming quite cheap (relative to non run flats), but my personal opinion is that I would rather have "normal" tyres on the Mini as the ride is soooooo much better. However, bear in mind that I don't use the Mini for long distance driving and I have a puncture sealer can.

Yeah, it's still a minefield out there, even after how many years...

I had a screw removed from my runflat Michelin Primacy yesterday. They put those little pads in there... :)
I noticed for a while now that the tyre 'seems' flat and when I checked, the pressure was like 400kPa... :mmm:

Very interesting info thanks :thumbsup:

When i spoke to a tyre dealer, he told me he had so many 19 inch wheels with RF's on that had cracked from hitting a small pothole
He then told me that the guys told him to put NON RF's on as the RF's on the 19" rims are just way to hard

He said he hasnt had any come backs from the guys since they fitted the NON RF's :)

E90 320 comes with run flat, was looking at buying one a while back. Got chatting to the guy who supplies our company fleet with tyres. He said that if i fitted Non run flat to e90 that it would void my BMW warranty :dropjaw:

Anybody else been told that ???

Yet more B$. Go to the BMW parts department and ask them to look up the OEM emergency wheel kit for the E90 (or you can check on RealOEM). Then go back to the tyre guy and inform him that BMW sells a spare wheel kit for the E90, if you fit normal tyres.

Check out:
E90 OEM Kit


I read a while ago that in some markets, the entry level E90 and E60 comes with this kit instead of RFT's.

i spoke to a BM dealer and he said that it does not matter if i replaced thr RF's with normal tires... so i called TWT, mintys. etc and they all said that i cannot fit normal tires to RF rims.. BUT when i told them that BM said i cud, they changed slaes pitch....

the prices for 18" RF's r just :shocked:

what to do.....

Never mind the price... what scares the :censored: out of me is the claimed mileage people are getting out of RF's. Apparently the very rigid design of the RF contributes to the quicker wearing down of the tyre. Guys claiming anything from 8 to 15,000 km's on a set of RF's.

I would be changing tyre 3 times ayear :):):) and at the Rf prices... that would go from :) to :bawling:

Also, from the various opinions floating around, it appears that run flats are also prone to punctures a lot easier than normal tyres. Hence, if you factor this in as well, it can become pretty $$$
