They are especially bad at motorway speeds. We do hardly any motorway cruising but we did a trip to Euro Disney in the summer holidays. It was half way down the m20 that I decided the run flats were coming off the moment I got home. The noise is literally laughable. It resonates through the whole cabin and once you are "tuned in" to it you can't unhear it!

Thank god for the HK system to drown it out.


When they came off, the first thing I noticed at speed was wind noise.... I had never heard wind noise in the mini and after a while I twigged that was because the original tyres were so noisy it drowned out the wind noise!


I know it's not ideal in terms of agro, but I'd get normal tyres speedbird..... if you sell the runflats on eBay you will actually make money on the transaction too!

No brainer for me. The car is so much quieter now.

Yes, I know I'm in the minority but I don't mind them. I've not driven a Mini without them mind you so I'm probably talking rubbish....

I've had rf's on my car during all it's 8 years of ownership and never heard the 'noise' folk talk about . There have been 4 or 5 times where I've had a puncture and been able to drive home then next day drive to my local tyre puncture repair guys and have the problem sorted without getting my hands dirty.

I posted this story in here at the time but can't find it now.

About 5 years or so ago I discovered I had a puncture on the offside rear runflat as I was leaving Oban after a weekend break there. Four adults (including myself) were in the car, and it being a Sunday there was no way of finding a garage open to sort it, also I didn't carry one of those tyreweld things in a can. The only options open to me were to either book another night in Oban for the four of us or drive it home to Glasgow on the puncture. I opted for the latter.
I was under the impression at the time (wrongly) that if I don't speed over 50 mph I'll be fine...and that if I don't drive a distance of more than 100 miles on it it will get us all home. (Oban to Glasgow is 105 miles ) I took the chance and sure enough we all made it to our destinations 3 hours later.
Admittedly the tyre was making a 'bit of a noise' by the time we got home also that it was totally destroyed beyond recognition, but it did get us home in the end.

I now carry one of those tyreweld can things in case it ever happens again.

So if you now carry tyre weld anyway then you may as well get off the rock hard runflats!





Make sure you have a pump on board though, the tyre weld won't do it on its own.





On the BMW forum I used to frequent during my ownership, there was obviously loads of chat about this. The most interesting aspect I found aside from the usual, bumps, noise, handling issues was the frequency of punctures.

There is a whole "conspiracy theory" idea that the runflats puncture way more frequently than non runflats. I am not necessarily agreeing with it but it makes very interesting reading. The conspiracy is that it makes more money for BMW.... in the early days of RFT only BMW could or would tackle them. Most tyre shops wouldn't... they do now of course but almost all of them still refuse to repair punctures regardless of the position on the tyre on a runflat. The runflat was designed in conjunction with BMW so it's all money back to them in one way or another. If they need replacing after every puncture that's a lot of tyres!

Mini first's "4 or 5 punctures in 8 years" is quite a a lot! Be interesting to see how my new "normal" tyres go!
