My CR-V didn't come with run flats or a spare. I managed to park on a screw at a hotel for a weekend and didn't notice it was flat until about to leave. My little air pump got it inflated long enough to take it to a shop. Run flats would have been convenient, but wouldn't have made much difference at that point. As long as you carry a 12V air pump in your trunk, you should be ok. And the TPMS will let you know when one is starting to deflate.

I would suggest staying with run flats....the alternative is calling a flat bed & hoping they don't damage your car or you sitting on the side of the highway with a plug kit & an air compressor trying to fix a flat while semi-trucks blow by you mere feet away
As I have said before in other tire discussions, all tires are compromises. You can get better wear, at the expense of grip and vice-versa. Better ride, better wet, better cold grip, better mileage, less expensive. all come at the reduction of something else.
The OEM tires were designed for the car, and the car designed around those tires, ergo the best all around that is possible.
Your car, your choice.
As an aside, all cars are compromises as well, You can always get more of one thing at the expense of another. i.e. more space, more seating, better mileage, lower weight, higher ride height. more tow weight, etc, etc, etc.
Michelin swears that the newer run flats dont compromise ride quality. Something about the sidewall. I can tell you going from Goodyear supercar whatever on my 08 to a conti non of? HUGE ride difference so much better. That car had mag ride too.
When I purchased my MRR forged wheels for my SR with MRC I switched to PS4S non runflat tires on that set of wheels. Each tire is approximately 3 to 4 pounds lighter and the ride was better. Between the lighter wheels and tires I was able to reduce unsprung weight by approximately 35 pounds.
On my ' Carbon Z06/Z07 (600 whp), I've had the original MPSS ZP, then Continental Extreme Contact Sport, and now back to MPSS ZP. No noticeable difference in ride, handling, traction between them. The only differences are: Contis wear better & are less expensive.
My '23 M2 (540 whp) came with PS4S non-rft. They were worn at 18k mi & I replaced them with Conti Extreme Contact DWS 06 non-rft. No difference in performance, grip, handling, ride between the Summers & All-seasons. Benefits, again the Contis cost significantly less & wear significantly better. I've got 16k mi on them & they're at 6/32nds.
Wife's '22 X3M Competition (510 whp) had MPSS ZP and switched to MPSAS4 non-ZP. No change in ride or handling. These wear extremely fast & are expensive. We received a 50% prorated credit for the rears and 25% pro-rated credit for the fronts. Hopefully front & rear wear more evenly this time so I can replace them with something other than Michelin.
I've also had both run-flat & non-runflat tires on other cars with no noticeable difference between them, Pirelli PZeros I believe.
Non run flats will defiantly provide a quieter and more plush ride and also better grip but at the same time you have to think about what 449er posted. Just the thought of my vette being hoisted up on a flatbed and possibly getting damage done is a huge no to me. Also being stuck on the side of a busy freeway with traffic buzzing by at 75mph or more is too dangerous. I would stick with the factory run flats.

Need to know what you want.
The tire you're looking at, the NT555 R2 is a serious hookup tire that easily outperforms any stock S4 whether it's ZP or Non-ZP. The NT555 G2 fronts match up with the sticky R2 rears. All this tire needs is a temp dash reading of Normal or Warm. Not much to ask in warmer areas.
ZP tires are just convenient. However they are heavier, wear faster, are more expensive and have less grip. Let the professionals speak on this topic. When NASCAR begins using ZPs we will know they are just as good as non ZPs. For now all we have is marketing and convenience.
My R2 rears 315/35/20, G2 are 265/35/19.
Wheels are .50 wider than OEM.
Just a couple of thoughts, I returned a 23 C8 with front lift to Carvana after having it for a week. I wasn’t happy with the condition of the interior so I returned it, when they came to pick it up the operator of the rollback said he forgot to bring the ramps that they use for cars that sit extra low needless to say watching him, drag that car up the rollback, even with the front lift engaged was a cringeworthy minute and a half all damage was to the front splitter but it sounded horribly worse.
Secondly, in the car that I ended up purchasing, a 23 C8 htc 70th I had a fist sized piece of concrete kicked up in front of me on a busy Saturday afternoon and although I did my best to avoid it without curbing it or hitting anyone else there was little time to react but thought I had missed it. After maybe 1-1-1/2 miles my tire pressure read 2 pounds had I not had run flats I would’ve been driving on the wheel by the time I noticed it was flat. There isn't very much of a volume of air in in these tires to begin with, you would be very surprised by how quickly the air escaped I know I was. And a can of run flat would have been useless. A Pic of the hole is below,just nicked it. Expensive Saturday drive but my son and I were able to continue to the cars and coffee and get back home safely and in addition able to take it to the dealer to have them check the wheel itself for damage, all told I am sold on the run flats and very thankful it didn't do any body or wheel dmage.

Modern run-flat tires don't inherently ride worse, make more noise, wear wors, handle worse, etc. than non-run-flat tires. The difference is in construction, tread pattern, compound, etc.
Here is a comparison of a run-flat and non-run-flat tire where the only difference is run-flat construction:
If you find tires that have performance characteristics you like that you like better than the OEM tires then you'll have to make the decision on what your priority is.
Anybody that is basing their decision on the run craps that came on the C5 and C6 are way out of date. The Michelin ZPs (Zero Pressure) are way better than the crappy Goodyear runflats. The difference is really unbelievable. I got rid of the run craps on those generations, but I would not get rid of the Michelins on the C7 or C8.
