Run-Flat Tires...
Bought my 2020 M8 last month.
I assume the orig Pirelli PZeros are non Run-Flats, correct? Has anyone replaced theirs with new Run-Flat tires? If so, which brands & where to purchase from for orig OEM size? Thanks, |

That would be a 20 M8 Coupe, maybe double check if you have the vert or GC. |

I think OEM PZeros are never RF's.
I never saw one M8 with RF's under the OEM delivery.

The way I do it is to take the sizing and go to the various manufacturers and see what they have; that was the purpose of the link: You can see what was there for an OEM tire and go shop around. Once I figure out what's available I start researching. For me, in this case, it would be a short search and limited to where I could pick up PS4s for the best price.
A quick search showed that sizing in a PZ and a Goodyear tire, possibly others, I didn't spend much time on it. I don't think Michelin makes a suitable run-flat but it would be my first stop as I've been a PS fan from the 2s. I apologize for not being more helpful, it's all I've got. |

Funny story , I bought my 840i last year used CPO with like 11,000 miles. New tires were put on, Continental SSR's. My previous BMW had Pirelli runflats, so I ASSUMED, like an imbecile, that these were non-runflats. Long story short, I hit a pothole, bent my rim, and lost all air in my tire, and because I Didnt think I had runflats, a whole lot of aggravation was added to this event. Waiting for tow 3 hours on a Saunday night, instead of just driving off to the nearest tire place. Ugh.
Anyway, I like my Continental SSRs, I always thought they were regular tires, and felt like it too. haha |

I do not believe you'll find a run flat option in factory sizes.
Go for the Michelin Pilot Sport 4S.

Have you ever had to change a tire, or try to use a mobility kit, in the pouring rain, bitter cold or less than desirable neighborhood? Or while wearing work attire, formal wear.....?

But to claykins statement, man that shit sucks when you have no where to go and its jacked up out there in the elements. I personally dont do RFS and my luck probably also has to do with road condition, debris free cities/roads, and just an overall more lack of need for them.

For long drives put a spare tire in your trunk and all is good... Even with RFs you cannot find that many shops that are able to repair them (assuming they are repairable) if something went wrong. If I'm travelling out of town and needed to change a tire for whatever reason, my preference would be get back home on a spare and shop for the right replacement tire as the tire sizes that we have on these cars are not usually off-the-shelf tires.

There's no complete win: Drag a spare on a road trip and you're taking up space you may wish you had for whatever. A foam kit will get you down the road quickly with small holes but wont work for bigger blows. Run flats have reduced performance and ride quality.
Solution depending you're still stuck for a day or so, in most cases, waiting for a tire. A pick your poison deal... |

Yeah, tell me again where the spare goes?? I have over 350,000 miles in BMWs with varying combinations of runflats and non-runflats covering High Performance Summers, High Performance All Seasons, All Seasons and Winter. Only had the occaisional slow leak from picking up several screws over the years - was always able to drive to get it fixed. Never had a flat, or been stranded - until last week. I made a bonehead move that required me to turn around at a construction site. The right front went down in less than a half a second. Got a dime sized hole where the sidewall meets the tread. It was a non-runflat Michelin Alpin4 winter tire. The wonder goo mobility kit was not gonna work. I got into a parking lot and waited an hour for a tow to the dealership, which happened to be only 3 miles away. A runflat may have gotten me there, but it was pretty ragged. Over my multi-thousand mile trips, I have been down some very lonely roads. I make sure my tires are always in good shape before leaving. They will not fail me because of wear problems, but there's no guarantee I don't blast something on the road - or make another bonehead move near a construction site. I always carry extra water, food, clothing, small shovel and tools. Been lucky so far. But, it's not enough to keep me home worrying about my tires. Shit happens. But, mostly it doesn't. 115 people a day die in car crashes in the US. But it doesn't stop all of us from driving. Runflat technology has gotten a lot better. My OEM RF Pirelli P Zeros actually give me a better ride than my NRF Michelin PS4s. Slightly less performance in normal driving, but not much. I don't complain about them. My favorite long distance trip tire may be my Michelin Pilot Sport All Season NRF. Good performance, but spring and fall trips across 11,000 foot passes and cool temps while up there (and the potential for snow) brings a lot of confidence over just sticking with my summers. Alas, there is no one size fits all solution. Just money out the door. |
