Nope, I have a hybrid and there's no room under the rear floor for a spare because that's where the 12 volt battery is. In fact you don't get a jack, you don't get a tire wrench to remove the tire bolts (not nuts like in the past), you get are you ready ....... a fricken screwdriver! so that you can use it to stab your eye out when go to look for what you have in your trunk to help with your flat that has left you stranded!
I carry a fix a flat kit that has a built in 12 volt air pump, I bought a jack, I bought wheel alignment studs to help locate the rim onto the hub while at the side of the road, since there isn't studs like most other cars have. Other than putting a spare in the back storage area you may be able to use roof rack cross bars and put a spare tire up there, where it will look oh so nice.

As much of a fan I am of having a spare, in this car is a no-go…

I've had 2 leaks fixed in my RFT's, one was substantial. If you get a side-wall puncture in either a RFT or regular, it can't be fixed. BTW, I don't mind the RFT Bridgestone's on my NX. They will need replacing at ~25K.

The great news is that when you put new RFT’s on the noise reduction is massive and the comfort factor goes up as well! Just like when you change them for non-RFT’s! 🤩

Same here. I replaced my 20 inch Bridgestone RFT’s with the same tyres at 30k miles and they still had 3mm on them.

If you compare RFT and non-RFT at 0 miles, you will find the difference in noise and hardness to be less. At 20k miles, the difference will be pronounced. This was my experience over 5 sets of RFTs when I owned a BMW with them. 2 sets were Pirellis, and there the difference was noticeable from the get go, and 3 sets were Bridgestone Driveguard with which I had the said experience.

The problem with RFT though is that they get noisier and harder than run flats as they age. Bridgestone has done a good job with narrowing the difference when the tire is new, but I don't think they are able to sustain as the tire ages.

I only have a little over 500 miles on my NX so far but from previous experience owning an Infiniti Q50 I knew I didn’t like the ride or sound from RFT. We went on a short round trip yesterday of about 90 miles and about half way home my wife, who drives the RX asked is it me or is your vehicle much louder than mine? I explained about the RFTs and she said you swore you would never have them again. She’s right. I did. But, I really wanted another fully loaded RX but I just couldn’t justify $70K for a vehicle to use as a second vehicle so I settled on the NX. I love the NX so it looks like it’s time for new tires soon. Not worried about changing flats. That’s why we have roadside assistance. They can tow it if needed.
EDIT: Do RFT’s make it feel like heavy steering. I’ve noticed from day one how heavy it feels steering the NX compared to my previous Mustang GT that I could set the steering to comfort mode on.

I also don't think the noise was all that bad. I probably got 40k miles on the 18" RFT Alenzas, with poor winter performance looming, and switched to CC2s. I did also buy the modernspare for trips. As one person said, the NX is not an RX level of quiet anyways.
But an interesting answer to the OPs question. The dealer probably can't do it on a new car as a free switch out before delivery because of laws on what must be included, i.e. spare or fix a flat, plugs, etc. I did get a tow eye from Nissan on that law last time.

The Pirelli (OEM tire) offered a firmer ride, a heavier steering, were noisier, and wore quicker (had to be replaced every 24k). The Bridestone Driveguards (non OEM), when new, felt more like regular tires giving a lighter steering feel, were quieter, provided a softer ride, and had a much longer life (would probably go to 40-45k if I let it). Problem with the Driveguards is by around 30k the noise was unbearable (worse than the Pirellis) and the ride got harsh. For whatever reason, the lighter steering feel didn't change. I actually preferred the steering with the Pirellis.

So I had the run flats put on last Thursday and immediately noticed the difference. Much noisier than the Michelin X-Ice tires I use for winter. The run flats have about 6&7 MM tread depth left, so will likely require replacement next year.
However, having watched the review up thread, I'm concerned. All tires are a trade off, but the stopping distance of the CC2's I was thinking of getting worries me. Seems that distance is much longer than a "summer" tire in dry conditions. My X-Ice tires have 9&10MM depth left (lots of life), so I'm reconsidering my options and may just put on some good conventional 3 season tires while continuing to do the seasonal swap.
