Runflats to Non runflats
Has anyone changed their tires from runflats to non runflats? If so, any difference? On the Mini board, lots of people have and noticed better handling and quieter. Only drawback, need to carry a tire repair kit and compressor.

No, I am very happy with my pirelli runflats. Granted, I am still in car run in mode but I do not have any intention to change my tyres to non run flats.
Welcome aboard.

I'm getting rid of runflats ASAP,
the pirelli is the only runflat available in 325 sport tire size, and I think they make too much noise and don't grip enough. they'll probably last forever since they don't grip much |

Remember that the setup of the car is made for runflats. Changing to non runflat tyres will affect the handling but offcourse all this depends on the type of tyre used. If you use something like 225/45 I doubt there is any difference. My problem is that in Finland we use winter tyres and they should be rather soft to grip well and the runflats are certainly not soft tyres...

I think it is marketing and liability. Run-flats seem convenient, allow for greater storage space, lighter weight, and less change of a snooty bmw customer having to get their hands dirty. Also, there were many complaints about other bimmers equipped with those tire-fix-it kits (eg, M3). If you can live with the tire fix-it-kit, I cannot see a downside to non-run-flats. Please, prove to me otherwise... and don't say because bmw says so! |

I'm not worried about the ride quality as much as tire wear, and frequent replacement on my soft sport-pkg tires. Some have mentioned replacement costs of $400 per tire - steep!!

i think that the run flat is something that we all have to get used to because in the future most cars will run on runflat.

I drove my E90 320i for 3 month´s with Continental run -flats .They are too hard for our roads here in Finland.You can really feell all bumps on the road.It is all differnce driving in Germany on their motorways .There run -flats are ok.I drove there in June.Two weeks ago I changed my tyres to Continental Contact 225/45/17" and the ride is much smoother and less tyre noise.You can also take the bumps like I did it with my E39 and E46.So my opinion is that somewhere else run-flats are doing a good job.

I will most likely switch to the non run flats. I think the on board tire pressure moniter will give enough warning that something is going wrong.
A can of Flat Fix will handle the other emergencies. |

If regular tyres really work and corner aswell as the runflats then I gues BMW should use the regular tyres. Still I doubt that a car manufacturer that builds such superbly handling cars would use runflat tyres knowing that they are not as good as regular tyres. That would truly be a bad marketing strategy.

If you do decide to go to non-runflats, a really cool and compact repair kit is the Slime "Smart Spair". Lots of people with Minis carry them. It would easily fit in the little compartment under the trunk. (that's where I keep my owner's manual and tire guage too.
http://www.slime.com/smartspairs/ Their office is less than a mile from my house, and I know quite a few people that work there. In fact, I just realized I know the girl in the picture on the website. (She works for them). It's a great product. If you get a flat, you add sealant to the tire, inflate with the compressor, and then get to a tire shop. You can have the tire shop wash out the sealant (which is biodegradeable) and then repair the tire and remount. |

Non Run-flats all the way.......cheaper.....smoother ride.....
and the treadlife is 2 1/2 times longer than the run-flats. IMO....economically make more sense.

Remember that the setup of the car is made for runflats. --- That could not be possible. Non run-flat should fit in. BMW puts in run-flat because 1) they want to show that they have a car equipped with advanced technology. 2) it save them cost of spare tire 3) the car is lighter and they can achieve better rate of fuel consumption 4) they just predicted that the technology of run-flat will soon be able to match that of non run-flat 5) etc. I will stick with non run-flat for now. The reason I buy a BMW because its superb handling (fun to drive). I don't deny run-flat but I will jump into it when it's more developed. |

Do you care about the lighter weight, more storage space, etc that the run flats make possible? No. You buy a BMW because it is fun to drive. So why would they put the second best tyres as standard tyres and lose the best possible drive, instead of using the best tyres there are and getting the best drive possible. After all that is what we do care about? It just doesn't make sense to me. If you use the same logic on the engine, BMW:s would have engines that are very economical but would not offer class leading performance. It just doesn't sound right, does it?

It seems that I'm going to get a set of non-RFT Nokians for the winter. Roads here are usually in poor condition and the RFT tires are too hard.
I've heard that many 1,3,5-series owners have changed from RFT to non-RFT tires. The run-flat technology has a long way to go, IMO. Both the M-division and Alpina refuses to use the RFT tires and that says a lot to me. I'm looking forward to some 17" wheels for the next summer, but haven't decided if I go with RFT's or not. Because of the non-RFT winter tires, I'm going to order the M-Mobility System anyway. The M-Mobility System together with the tire pressure monitor is a great alternative to the RFT tires, IMO. |

Hornet I hear that there are new runflat winter tyres (finally) coming and that they should work well. So they are not the standard "European" model of last winter. Aika näyttää
My current car has 225/45 tyres and the 320i that I tested had the 205/55 tyres and I must say that the E90 is much more comfortable than my current E46. Maybe the bigger runflats are harder then? I feel no need to change the tyres, especially because in a couple of years most new cars will have runflat tyres and then the tyre choices will be greather. It's like the ABS brakes (a BMW first), now even little Japanese cars have them.

but they only had the pirelli's available in 325 sport pack size, 330 sport pack has the bridgestones (which are better) maybe it's a weird US deal where pirelli has exclusive rights to that size for a limited time in exchange for developing that size for BMW |

Indeed, finally Nokian launches its new RFT-winter tyre range. I'm glad that now there are good RFT-winter tires available also. It's true that the RFT tires will become more common in the future, eventually becoming standard in all cars. I know they will get better in the future, but at this moment, I don't know if they are good enough. |
