I think Toyota makes a compatible spare tire rim, say one used in Camry, Prius v, or maybe even RAV4? And for the tire, get spec from Owners Manual, check on TireRack. @Hammersmith has this all worked out I think.
Does it have to be third-party? The following is OEM spec for all gen5 Priuses. Plus it's a whole lot cheaper than most third-party spares. $70.64 - Wheel | Part #4261121280 | Toyota Auto Parts (add a pair of wiper blades to get above the $75 threshold for free shipping) $101.04 - https://www.tirerack.com/tires/tires.jsp?tireMake=Yokohama&tireModel=Y870B&partnum=49MD6YOTEMP (your exact tire and price might vary slightly depending on your location) Find a set of tools at a salvage yard and/or throw in a cheap battery impact wrench with a 21mm socket and an adaptor for a scissor jack.
Interesting story on why EVs don't have spare tires.. https://www.msn.com/en-us/autos/news/why-your-new-electric-car-won-t-have-a-spare-tire-and-why-you-probably-don-t-need-one/ar-AA1frUQR?ocid=socialshare&cvid=8220b32f44db43998c6e1e42cae1782d&ei=17
Many ice cars don't have spare tires now either. Cost savings. Just because many electric cars don't have spares doesn't mean they all don't have spares. Take the Ford Lightning pick up for instance. It's not only got a spare tire, but it's full-sized too. https://fordauthority.com/2021/06/2022-ford-f-150-lightning-will-come-with-full-size-spare-unlike-competitors/ .
From the article: Ditto for hybrids; the Toyota Prius, for example, hasn't included a spare since 2016. Not exactly true: some levels had spares, the "lower" levels if I'm not mistaken, which is a little absurd. Besides chiseling the customer, the higher levels purportedly nixed the spare because they had more accessories or whatever, to keep the weight down, and with the AWD levels the engineers made a less-than-inspirational decision to plunk the rear motor's inverter (or something similar) where the spare would have been. There's one simple way to reverse this trend: if it doesn't have a spare, don't buy it. The manufacturers will get the message right away...
Thanks, everyone, some good information here, but kind of a "beginner" question ... let's suppose I get the wheel from Toyota and the actual tire from tirerack.com (or elsewhere), how do I put them together so they can be used?
Any tire shop can do this. Well hopefully , see final bit for rebuttal. Tirerack can ship the tire to you, or to various tire shops. Or, if possible, just purchase the tire from a tire shop in your area, maybe after researching on Tirerack. Check with dealership service departments too; they usually do tire mounting, and it could be one-stop-shopping, they’ll get the rim from parts dept, obtain/install appropriate tire. FWIW, I contacted a local-to-me tire shop about replacing the temp spare tire on our ‘10 (due to age), and: 1. they don’t offer for sale any temp spare tires. 2. even if I could get one, they said they wouldn’t/couldn’t mount it. I’m a little puzzled by this; it was Kal Tire, a respected retailer in western Canada.
Take the wheel and tire to a local tire shop and they will mount the tire for you. If you have a Discount Tire or Americas Tire store near you, they own Tire Rack and you can get the same tires from them. Tire Rack will also have a local network of tire shops that they can drop ship to and you can take the wheel to that shop to have them mount the tire.
