I never liked run flats for the ride, etc. I use performance summer tires and dedicated winters.
But I always keep a spare. With a little investigation you can find a setup that works. People complain abt taking up trunk space etc., but I've never found it to be a problem. I have a setup for sale that fits e90 and/or f22. I'm in Chicagoland, let me know if you're interested. I feel lucky I've only had 2 pothole punctures.

I've had a shocking experience with RFTs (I think you're on the same P7 Cinturatos I had) in the pothole infested Philly area. 5 in just under 2 years including 2 full blowouts. These tires are rubbish fragile.

Just dumped mine for regular tires and hoping the ride quality improves noticeably.

I had the Bridgestone S001 staggered, summer RFTs for ~25k miles, never had an issue with potholes around LA. The Pirelli Cinturatos must really suck.

Replaced them with go-flat Michelin Pilot Sport 4S and could not be happier. Better ride, turn in & traction, with less road noise. Plus, they are about half the cost of the Bridgestone S001 set-up.

Have AAA & more than one vehicle, so don't really care about the lack of spare tire situation.

Also, put Michelin Pilot Sport A/S-3+ on my wife's Subaru (PS4S don't come in that size), while not quite the PS4S, still a fantastic tire!

My Conti5 runflats were 'kind' enough to cup-wear to death at about 7k miles, so I never got a blowout. Switched to nonRFT summer tires (Contis, then Bridgestone s007's) and havent' had any problems, ride, noise, and grip all superior. I sincerely hope the RFT's really are saving a bunch of lives by not having people change tires at roadside, otherwise they are one of the biggest shams yet.

Why do you keep fitting them then? After the second or third blowout you should try to either a) avoid potholes b) switch to nonrunflats c) get smaller wheels, because obviously if youíve had so many punctures, itís bound to happen again if you change nothing.

as a driver who keeps re-fitting these P7 run-flats: (1) i like the safety of the run-flats. i drive the DC beltway and surrounding highways and there's just NO EFFING WAY that i'm stopping to change a tire on the side of any of these roads. i've done that once in 20 years of commuting (in my X3) and it was the most frightening experience of my life...drivers around here are completely insane idiots. run-flats have never failed to get me to the shop for a change, and (2) i really like the look of 18" wheels on this car, so i'm not down-sizing.

my commute is fairly consistent (or at least it was pre-covid) so becoming MUCH more aware of potholes has helped me significantly after the first 2 years and 5 blow-outs.

RFTs suck. Period. Put a st of PSS on the car. Record the serial numbers. Michelin will pay for the tow to wherever to get your tire fixed. PSS are the only tire I'll put on my M240i.

Got tire insurance for 4 years when I got the car, so just have to bare with it
