Purchased a spare for our 2025 Crown Signia from EZSpare. Both EZSparewheel.com and Modernspare.com have good quality alloy rim/wheel spares. Modernspare.com mounts Continental tires, the EZSparewheel one had a Chinese branded tire mounted. SM-G781V ?
I'm intrigued by current options. When I was a lad, the roadside tire change involved operating a scissor jack with a short lever and then dealing the the bolts with a fairly stubby iron. I see impact wrenches that will work a scissor jack and break and tighten bolts/nuts. That would take a lot of the misery out of the process.
The Toyota supplied scissor jack is a poor design, in that the part you twist is a single eye, made of soft metal that spalls when you look at it: For comparison, a Honda scissor jack is a bent-plate U-shape with:two holes, much more stable: That said, it's not a major hassle, especially when you're "motivated".
Even if you buy into the Roadside Assistance solution if you read the small print when it comes to flats it says "mount customer supplied spare" which, if you don't get one on your own, you won't have.
There's plenty of room for a spare. The reason it's not included is twofold. 1) Cost. 2) Weight (to eek out an extra 0.001mpg).
You must live in a good part of the world where roadside is close and fast. That and I wish I had your flat luck. If I am out on a road trip an hour plus from the nearest big town, I will be begging for a spare in the first couple of hours.
I use a spare tire coming from Acura car (T135 70 R16 tire installed on 5x114.3 wheel, need an 60.1 mm adapter). It's working fine. Spare tires from Honda cars have the same bolt pattern, just check the CB.
I'm looking to buy a spare for my 2025 Prius from a junkyard. I've read that a spare from a Prius V will work but none of my local junk yards seem to have a Prius V on their lots. From my reading, it seems like the base requirement is a 5x114.3 lug pattern. Googling this lug pattern yields a large number of vehicles that have this pattern: Toyota: RAV4, Camry, Highlander, Tacoma, Solara. Honda: Accord (V6/newer models), Civic (Si/Type R), CR-V, S2000, Odyssey. Nissan: Altima, Maxima, 350Z, 370Z, Murano, Rogue. Mazda: Mazda3, Mazda6, CX-5, CX-9, MX-5 Miata. Ford: Mustang, Explorer, Escape, Ranger, Edge, Crown Victoria. Hyundai/Kia: Tucson, Santa Fe, Sonata, Sportage, Telluride, Tiburon. Infiniti/Lexus: G35, G37, IS300, GS300, RX300. Subaru: WRX STi (certain years), SVX. Does anyone know if spares from any of these vehicles will work as I'm sure the junkyard is likely to have one of these vehicles junked in their yard. There's an even more extensive list of 5x113 lug pattern vehicles by mod4l and year at 5x114.3 - Bolt pattern | Wheel-Size.com
Yes, planned to do "test it out" before I leave, but I also don't want to just randomly choose cars to u-pull-it" the spare from. If I know spares from these cars will fit, I can online search some junk yards to see if they have a vehicle who's spare will fit.
You're looking for three things: A bolt pattern of 5x114.3, a hub size of 60mm/60.1mm, and an overall tire diameter of about 26.4". Just because the wheel fits on the hub, doesn't mean the tire is the correct size(diameter) for the car. The stock spare wheel/tire for the gen5 Prius is a 16x4 wheel with a T145/90D16 tire. If your potential spare wheel has a hub diameter of something greater than 60mm, you can always use a hub centric ring as a spacer, but it's just easier to get the correct wheel. Also remember that tires have a shelf life. The absolute max age I'd go with on a spare is 10 years. And really you shouldn't use one older than 8 years to be safe. Most/all tires today should have a 4 digit code molded into the sidewall somewhere. The first two digits are the week of manufacture and the last two are the year. So if you buy a spare from a junkyard with a code of 2520, that means the tire was made in the summer of 2020 and really only has about 2-4 years of life left. So you might just want to consider a brand new wheel and tire instead of one from a junkyard. The proper wheel is 42611-21280 and you should be able to find it for between $62 and $68 brand new from the right dealership during a sale(the Memorial Day sale is just around the corner). The correct tire costs about $100-$125 at places like Tire Rack. Add about $15 to have it mounted at your local tire shop, and you're looking at around $190 for a brand new setup that's the perfect size for your car and will be good for 8-10 years. Just some stuff to consider.
I know this was posted a while ago, but it looks like there's a way to add an OEM spare to a Crown Signia. The only problem is that it's really expensive to do it right. You also lose a bit of storage because it raises the floor an inch or two. Just for the sake of argument, this is the complete parts list and best case prices as of late April '26(inc. 25% off sale): $69.69 - 4261B-30010 - Wheel - the OEM spare wheel $8.79 - 90942-05009 - Tire valve - I don't think you necessarily need this one; a generic one from a tire shop would probably work $142.38 - T165/80R17 - Tire - available from tire shops or Tire Rack (I picked a Yokohama from Tire Rack for the price) $119.10 - 64777-30120 - Cushion - goes under the spare tire to center and level it $10.08 - 51931-33270 - Carrier - bolt to hold down spare $104.61 - 58412-30020-C1 - Deck board LH - small deck board/trim on the left side $97.37 - 58411-30030-C1 - Deck board RH - small deck board/trim on the right side $521.81 - 58410-30050-C1 - Deck board - the big one $40.61 - 64935-30010 - Holder, tonneau cover (x2) - side effect of the taller deck board is that you now have a place to store the cover $113.76 - 09111-28150 - Jack $28.20 - 09113-30060 - Handle, jack $33.63 - 09151-78010 - Lug wrench $5.17 - 58792-48010 - Support, jack carrier - I guess this clips to the car and holds the jack in place while stored? $10.60 - 0915A-53010 - Socket, hub bolt - I think this is a simple plastic tool to make it easier to start/remove the lug bolts $17.76 - 0915B-53010 - Pin, wheel guide - this is a simple tool to thread into the hub to make it easier to mount the wheel to the hub So that comes out to about $1,325 best case if ordering from US dealers. Ordering everything but the wheel and tire directly from Japan brings the price down to around $600, but you'd probably be looking at $600-$800 in shipping because of the big pieces, so I don't think there's any real savings doing it that way. If I absolutely KNEW I was going to be holding onto the car for 10+ years, I MIGHT consider it(the Signia was on my short list after the Prius, so that's why I went down this rabbit hole). But $1300+ is a giant pill to swallow just for a pretty spare tire install.

I think the gen5 lug nut works with both tapered and flat seats, so it probably doesn't matter. But probably isn't the same as certainly, so it wouldn't be the worst idea to bring along a lug nut to test if a person is going to the junk yard themselves. Here's a pic: The tapered portion at the end fits into my OEM spare steel wheel with tapered seats, while the flange in the middle is used for my regular full-sized alloy wheels with flat seats.
And offset. Some of those wheels (Subaru and Nissan IIRC) will have a large hub size you could fix with an adapter ring, but Honda wheels are apt to have a very different offset.
Would that matter for a spare? Most spare wheels are around 4" wide compared to 6.5"-8" for a regular wheel(6.5" for the gen5). So I wonder if offset becomes mostly irrelevant with a spare? I don't know either way for certain, but it seems like most any spare would clear calipers on any reasonable offset.
I don't know. I have a full sized wheel and tire as a spare and am looking for a wheel set for winter wheels, so I was also aware of the offset differences. I believe the envelope of what will fit over the front brake and also not poke out of the wheel well may be smaller on the Prius than on a Camry/Rav4/Sienna. But I imagine that you are right - for a donut the offset envelope should be much more generous.
