Another Question About Run-flat Tires
So far, the only things I have heard about run-flat tires is that you can drive on them for a while after a flat but that they are heavy, stiff and expensive. From this, I would think that it is safe to assume that the casing construction is a lot different from non-runflat tires. I am curious to know whether this difference has resulted in any difference in puncture resistance (through the tread) for better or worse than non-runflats. I am only guessing but I would think that tread life is more or less independent of casing design and construction so I wouldn’t expect much if any difference there. Anybody hear anything about puncture resistance?
Thanks, my apologies if this has already been answered in this forum and I missed it. |

The sidewalls are thicker - not the tread (as far as I'm aware) so can't see much more puncture resistance unless the offending item enters via the sidewall.

The tread is the same as normal tires, so puncture resistance is the same.
For interest: A friend drove over a 100miles on his runflats with a 2" hole in his tire after hitting a rock or something on the highway and he felt no ill effects |

I hit a pothole in my E90 after havng it one month, middle of the desert. Split the sidewalls on two tires (left side) and drove it 120+ miles home on the run flats @ 50 mph.
Damage report: Needed two new wheels / tires. New front strut and strut plate. Alignment. Rob |
