If you hit a pothole the probability of having a bubble in the sidewall is quite high.
You can have the sidewall cut if the speed is high. You'd better have an assurance for the wheels! |

I upgraded to 20" wheels a couple of years back, and transitioned from runflats to Pirelli PZero's back in September. Have been loving the new rubber ever since! Yet, last week, I hit a nasty pothole and it immediately deflated my right-front tire (along the sidewall right under the alloy wheel's outer rim) and put a nice bubble on my right-rear tire (high along the sidewall near the tread).
Both were replaced to the tune of $757, and I've subsequently filed a claim with the local municipality that failed to properly maintain their roads. What concerns me from this point forward is that fact that the softer and more compliant/responsive non-runflats aren't as durable (translation: stiffer) when it comes to road hazards, as I know for a fact that I've hit some pretty gnarly potholes here in the Los Angeles area before the tire change that were much bigger and the dreaded runflats handled them without issue. I guess that's the tradeoff of having a stiffer sidewall (and less performance-oriented) tire vs. an "ultra-high performance" rated tire in the form of PZero's... As a sidenote, I called BMW Assist for a flatbed tow, and was informed that they'd only tow my ride to a BMW dealer for runflat replacement. If I wanted to tow my ride to an independent tire shop, I was quoted $170 for this pleasure via BMW Assist. I ended up getting a flatbed via my AAA membership (gratis). Something to consider for those that switch out of BMW recommended RFT's and how it impacts the disabled vehicle status (as a result of a flat tire) when relying on BMW Assist for roadside assistance.

Thank you everyone.
I asked because I never got bubbled before runflats. Always thought runflats were more prone to bubbling due to stiffer sidewalls (less give)...? |

Before I started using runflats, the tires just goes flat and sometimes mess up my rims depending on how fast it deflates. I do see that runflats tend to be easier to bubble. I think it's a good tradeoff. If you've ever had a flat during heavy traffic on the driver side, it's a PITA and relatively unsafe to put your donut on. Getting your car towed can take hours sometimes. You'll miss work, appointments, meetings, etc... With runflats, I can just keep moving, drop my car off the next day in the morning and receive a loaner in 10 minutes. My day isn't interrupted.

I've only ever had one flat on a non-run flat many years ago on a Range Rover when I parked in an overflow parking lot next to a restaurant at night during a party; not fun changing a large wheel in nice clothing in minimal light, but run flats are just too expensive and prone to failure. I get so many bubbles that the time spent going to and from the dealer is a huge headache. The stiff sidewall also transfers impact to the wheels and easily bends same. Wish our cars had integrated space for a spare. |

But I changed my car to non runflats because flats do not always occur within 50 miles of a company that has that runflat in stock or may not even be open that day. |

Consider yourself lucky. With our crappy NYC roads, I am prone to at least one per winter. Was even worse on my previous cars because I was running even thinner tires. Hoping for better luck this winter.

New territory ahead with low-profile non-run flats I suppose! Eek! We'll see. Thanks! |
