really works!! Today my 2009 330i coupe experienced this first hand! Was on the highway going 120km and something fell of a truck one my tires hit the stuff that feel off, you can see a crack but it was still able to drive me to a secure location to have them changed!! run flats are awesome!
I have RFTs on my E60 525d, first time ive experienced them, regular driving is fine, no different than conventional tyres, however, I have noticed some "snaking" on the motorway on cruise control past 75mph?! Amy ideas?
It seems there had been many BMW owners who really dislike the run flats. Run flats seem to be more prone to nail puncture and pot holes than conventional tires, based on significant number of user data. Dealers who are willing to disclose info say they experience much higher rate of tire fixes for run flats than conventional tires.
RFTs are convenient but very expensive. If you don't drive like the guy in the video, you are better off with regular tires. Most people rarely have flat tires and most people don't drive roadsters where there is no trunk space for a spare tire. Also AAA insurance provides road assistance to replace your tire in case you get stuck. If you have slow leak, you can still get to the nearest service station within a mile or two with regular tires, just drive slow.
This technology would mean more expensive tires and added waste materials, instead of reinforcing the sidewalls why can't they use the other technology of a thicker strip of rubber attached on the rim..
I have a BMW 540i. When the first owner bought this car in 1994, he selected the motosport wheel option. This rim takes 240/45/R 415. This is not a mistake in any way, This is exactly what it says in the owners manual. Also on the inside door well of the car.
Please help me somebody cause I can't find these tires. Even online.

The benefits are clear but there are also some tradeoffs with RFTs. For one there is absolutely no deflection in the sidewall since it is reinforced so every little bump and crack in the road you will feel and hear and in some cases it will violently rattle the car. I went over a small pothole I didn't notice once and it actually made my radio skip. It's also possible to momentarily lose contact with the road i.e. taking an onramp at 30+ mph and hitting a bump causing the car to 'skip'.
It's more important to be safe, so even if you're on a bumpy ride at least you can keep going. In the case of the Presidential State Car, it's more important that he's safe than if the car's suspensions go completely wonky
When airless tires come around, it would be great.
@juj1n That's true. I drive a Z4 and I can feel the road so to speak. I can feel every bump and hole that I run into and it rattles my little car. It negates your car's shocks. It's like taking a beating from the road. If you don't like a hard ride, i'd recommend against it. If you don't drive like a crazy and you don't mind the inconvenience changing tires on the road or waiting for your insurance to change it for you, then save the money and buy regular tires.
I should add that not many shops sell RFTs. You have to pre-order it or buy it online at TireRack. So while you wait for your tires you can use your car as long as you pump air in it every time the red flat tire light comes on. I don't know how long ago the video was done but Motorweek should have mentioned that RFTs, contrary to popular belief, can be repaired (patched inside according to Bridgestone) The public was lead to believe that you have to replace RFTs whenever you have a puncture.
great video,nice demo. Last time i saw the video of electronic stability control and ABS. I am wondering how highway saftey research are helping to bring new innovative saftey features to save life. BMW and Mercedes and not to forget volvo are all great companies
Yo no los quiero ni regalados, prefiero los neumaticos convencionales. Las Runflat son demasiado duras y hacen mas incomodo el coche, son mas pesadas con el consiguiente aumento del consumo, agarre en curva y aumento de distancia de frenado, ademas son mucho mas caras que las convencionales. Si pinchas y caminas con ellas hasta el taller casi seguro que tienes que poner una nueva de lo deformado que esta. Lo dicho...para quien las quiera.
asi era antes perodesde unos años para aca varios carros fueron diseñados para traer estas llantas y por lo tanto ya no se desvalancean ni hacen inercia yla suspension esta hecha para traerlas asi que ya nada de eso pasa pero nunca han perdido rigidez de echo sale mas barato si tu carro es delujo o le metiste rines por k asi jamas podras dañar el rin al tener de esas. si recuerdo cuando empezaron k la verdad si eranmuy incomodas estas llantas son buenisimas cuando vienen de agencia, nadamas
sabes k no es sierto viendolo bien si es un problema por k a un amigo se le poncho y sila tuvo q cambiar =S como que solo conviene si sales a carretera
If you get a nail in one you have to buy a new tire you cannot fix it like you would a conventional tire, 388.00 per tire including installation around 450.00 per tire. Just had it done. What's the trade off here?
It's all a cost/benefit analysis. Didn't you watch the video? There's two benefits here: no stopping on the side of the road (VERY dangerous, especially on highways or in sketchy neighborhoods) and added safety. While the BMW car assistance program gives free towing, many towing companies (many times joe six pack's towing) don't know how to properly tow German cars (there's a hook on the bumper). If you can drive to a dealer, no worries about added damage.
You or your family weren't stuck on the side of the road in harm's way?? It's a peace of mind. Wheel and tire protection great idea to purchase when running runflats though.
When I have gotten a flat I get them plugged and they have worked fine. Cost 5.00 a tire to plug.
They are noisy....by the way I love my BMW 328i Coupe 2007.
