I'm pretty sure I can feel the difference between my 135is run flats and my winter run flats, and my summer tires. I wouldn't bet big money on it.
I'm going to keep the non run flats but when they wear out, as they surely quickly will, I suspect I'll go for a run flat next time, maybe even a high performance all weather, as it gets wet here more often than one might like. Will continue with real winter tires/wheels as well. |

I have these on my 2 and love them. Better than the Michelin PSS.

In the rain, yes. Dry traction, down on grip, but most wouldn't see the difference. I pushed hard on AS3's on my old GTI before getting PSS's to replace them. The PSS's had noticeably higher dry grip at the limits than the AS3's, but definitely down on wet grip, which is more important for most DD owners I'd imagine.. I always recommend the AS3's to the locals who want the best bang for buck performance tire, they've always come back raving!

That they do. I've tried to grow accustomed to it, but some days that's all I hear unless I crank the stereo. That's my only complaint about these tires. Dry, wet, and snow traction are every bit as good as claimed. I guess not all great things come without at least some detraction.

Very newbie here: I have a question re: 228i (normal) front tires beginning to show uneven wear on outsides. Rotate? Or not. (Non-Run Flat tires)
Also: What torque used for tire bolts? Thanks Last edited by Shatzbot10; 09-28-2018 at 03:20 PM.. Reason: Added “Non-Run Flat” for clarification. |

Be sure to drive at high speed if you change
I got regular tires on my 135 instead of run flats. They were totally fine until I drove 70 mph. Then my car wobbled side to side as if I was behind a tractor trailer. The tire dealer replaced them for free w run flats. I’m sorry, I can’t remember the make of the tires. But if you switch, I definitely recommend getting out on the highway sooner rather than later in case you have the same issue.

Nope, it wasn’t. I had to drive all the way from Georgia to South Carolina with it doing the back and forth. Had a death grip on the wheel. It could’ve been just that particular tire but we heard afterwards that it was a problem with using standard tires on a car designed for run flat. Thought I should mention it...some people might not get on the interstate for months when it’s too late.

Already posted how BMW highly frowns on replacing RFTs with non-OEMs. But tons of people have probably done this. Yes, could have been tire, or specific to 135, or both.
What are you running in your m240i? |

A death grip on the wheel and incorrect tyre pressure will cause the car to move around more, as you are constantly correcting out of phase with the tyre movement. A relaxed grip allowing the tyres to move a little without over correction tends to let the car track straighter, you just tend to feel the steering weight continually changing and telegraphing the road irregularities, as opposed to continually over correcting to the feedback. |

I didn’t mean to start a conversation about which tires are best or how best to drive. All I know is I wished I’d done a trial run at high speed before I set off on a lengthy trip, so I thought a “heads up” might be appreciated. I never had trouble once I had run flats back on the car and the tire dealer agreed it was a problem with the tires, not inflation or driver error. I don’t know what I have on 240 - whatever came from the dealer 😃 Obviously I don’t know all that much about cars, or tires, just that I like to drive fun cars. |

A bad tyre could cause pull that you may have experienced, but it wouldn't be due to run-flat vs non run-flat. Tramlining as a characteristic can happen with any wide low profile tyre, irrespective of it's design. I expect the tyre dealer was happy to sell a set of tyres as opposed to getting to the root of the problem. It is just false information that the current cars are designed or engineered specifically for run flats. I'm glad you don't have the problem now, but if you want the best performance out of any sports car in the future, run flats and/or all-season tyres will be inferior to pure non run-flat summer tyres for non-winter use. |
