run flats vs regular and spare

In addition to the issue of run flat vs. regular + spare, I have found that the all season tires don't match up to the handling ability of the car. I have a Ti with the 19 inch sport package. I'm feeling like I should get a set of high performance summer tires, and high performance winter tires. I've never had a car with run flats. Is that part of the problem, or is it just the fact that they are all season tires? Curious if anyone else agrees with my observation.

It's my first car with run flats, but from what i heard from BMW owners they are not as sticky in dry and also ride is harsher.

If you live where there's snow I wouldn't recommend run flats. They are a lot more slippery in wet weather from my experience and definitely not as sticky as all-season regular tired. I ordered my Ti with the 3 season tires so I'm wondering if I will get a spare or not? I should be getting it in the next month or so, I'll report the results.
I could be wrong on the run-flats as design has improved on them the last few years. I'm basing my comments on a 5yr old run flats (mini cooper S).
You won't get a spare - there is no place under the trunk liner, just a hole big enough for mobility kit, and that only comes with the Q.

Please keep us updated on what you find out. I want to switch to the PS4Ss myself. Would love to do it thru the dealer - but I will do it either way.

If you have the run flats, the spot under the trunk floor where the pump would go is a great place to put the owners manual, which is too big for the glove compartment! #ProblemSolver
I'm going this exact route in a few weeks. I'll make sure to post an update once I pit the PS4s on.
Awesome. Please tell us how MSS are. What size will you be getting? Just a reminder MSS run wide and sidewall is tall.

Run flats have saved my bacon twice. Drove home about 15 miles one day on a blown rear right. I have them on my current BMW (535 GT) in both summer (P Zero RFT) and winters (Dunlop Wintersport 3D). There's no way I'd ever drive it with All Seasons.
My tire guy stores my offseasons for me so it's no big deal. I'm not a RFT hater by any stretch but if you're all about performance, you might not like the general stiffness.
So I'm guessing the TI has RFT standard? The base Guilia I'm looking at doesn't seem to indicate TPMS.

According to a PDFs of the manual (I don't have the car yet), there are provisions for a full size spare and compact spare. I realize they are not options from the dealership. We would need to pull out the big styrofoam block, but a spare should fit.
I did something similiar with our Volvo V60. The car doesn't have a spare either so I bought a compact spare in eBay. Removed the bottom strofoam tray and cut a hole in the mid-tray. The top tray/carpet lays perfectly so you can't tell.

from BMW experience I take Michelin super sport over any all season run flats or not. My BMW mech insisted on removing run flats to save suspension
Ride quality is different, more grip, less noise, bit softer glide.
For Canadian climate supersports and winters just ideal.
I had always repair kit from Amazon in my trunk
