Question Run Flats v. Non

I live in NYC and am upgrading the wheels on my e92xi to 18" staggered 189's. I am putting winter tires on my stock 17".

My question is - with all the MASSIVE potholes in NYC will run-flats be a better choice even though they don't feel as good and don't allow the cars limits to be appreciated? I have already had one bent rim on my car and I am wondering if the propensity to blow out a tire on a bad pothole is higher with non-rf or if the only difference is stranded or not?

Thanks for any thoughts

My view is that run-flats are better in a potholed environment 'cos of the stiffer side walls.

RFTs ride harder due to the stiffer sidewalls. In NYC, it can become jarring and annoying quick. I had the 18" Bridgestone RFT summer tires but now I'm riding on 17" all seasons non-RFT. Ride is more compliant, but turn-in/handling isn't as crisp. However, I dont cringe as much going over potholes. I'm debating going back to RFT's now that winter is over.

im on 17in summer micheline ps2s. love it now, having just ditched winter dunlops 16in RFTs. Ride is so much nicer.

IN pot hole environment? Ok, but remember that you cant repare the frigin runflat without issues with BMW if its a lease. No such issue with regular tyres, plus its cheaper, much chearper.
