Downsizing wheels on 2022 NX 350h

I bought the spare and jack on ebay, spare for $229 and a jack for a Mazda CX9 (don't buy one of those cheap jacks for $20) . The seller for the spare has one listed that works if you have 18" wheels,165/70 18 tire. If you have 20" wheels you need a 165/90 18 tire which is what I have..
You actually would want the 165/90/18 spare if you have 18" or 20" wheels as you want the spare as close as possible to stock diameter.
stock 18" 235/60/18 = 29.1" diameter
stock 20" 235/50/20 =29.3" diameter
165/90/18 = 29.7" diameter
165/70/18 =27.1" diameter

Do the NX lug bolts work with the spare? Best to test fit before you would actually need it.

Unfortunately I don't pick the car up until 12-15 April so I can't see if the bolts work. Having said that, The Kit came with a set of 5 bolts. So, I'm guessing they know it doesn't fit.
As for the spare, the wheel is 18" and the tires are Kumho 131 and it is T155/90 R18.

Your spare, how tall is it? I understand spare wheels tap out at 18" wheels. So we with 20" ones, unless we downsize, we have to have the taller tire so that the set (tire & wheel) are the necessary 29" high. So is your set 29"? If so, ten it is the same height as the one I have. I was wondering if there was something that would be smaller that would work but I guess since the other 3 are 29" then the spare has to be 29" or extremely close to it.
Different subject: I had a cohttps://tiresize.com/comparison/uple of Subaru's a few years back. Their AWD is what they call Asynchronous (sp?) and if you change one tire you pretty much had to replace all 4. Is the Lexus AWD the same? Do you know?

As to your other question all Subaru's years ago came with full size spare tires but not any more. We know all Subaru's have AWD but some/many/most now have a temp or "donut" spare that is the same size as the regular tires. I would guess "same size as the original tires" is the key for the AWD. If the tire size varies to much on any AWD system it get's confused and want's to put more power to the smaller tire (at least that's the way I understand it). I don't think my NX will know the difference in 1/10 of an inch (nor would a Subaru AWD system), you would have that much difference if you had 3 tires with 37lbs of air and one with 33 lbs.
I am no fan of our 2022 NX 350 AWD loaded Luxury and will trade back to BMW in 24 (I hope). I have a 2020 X6 but my wife wanted something smaller, last year (and now) the X4 is about impossible to find. That's how I ended up with the NX-----------------------------9 months old with 1500 and change miles. My wife would rather drive my 2022 Honda Ridgeline RTL- E Black Edition than the NX.
Hope I've been of some help

You can get them from Tire Rack. I kept my 17" winter tire/wheel setup from my 2021 RAV4 Prime to use on the NX 350h, Tire rack sent me the proper lug bolts for $20 for the set of 20.

They should fit the same as the Rav4 Prime. NX offer 20' or 18" wheels, R4P 19" or 18" wheels. the biggest difference is the NX uses lug bolts and the R4P use lug nuts.

The problem with that is they changed to 14x1.5mm radius BOLTS for the 22-23 NX's instead of lug nuts and studs … They made is so complicated on us to save a few bucks. Local parts manager said the new design 23 RX's still take the old school wheels and have studs like before. The new design UX,NX and IS are the only the only Lexus to get the new radius lug bolts. Maybe it's a social experiment!

Damn. I wish we were closer. I want the exact opposite, to trade my 20" silver wheels for the 18" wheels on my 5 week old 350h. I am in the Albany, NY area.
