OEM spare tire install

There is a YouTube video of someone installing all the parts along with a list of the part numbers which are the same parts listed in this thread. I’m still waiting for my Prius XLE AWD to be removed from a quality control status : / so I haven’t purchased the parts yet.

 

As expected, the spare is "where equipped". Attached Owner's Manual excerpt has more info. It's also drool-worthy, you can see all the stuff you don't get:

 

Interesting. Gen 4 Prius Prime already comes with the jack and tool bag despite having no spare tire. For Gen 5, they provided the slots for the jack and tool bag but they asked you to buy them from the dealer separately.

New to PriusChat, so I clearly have a lot of reading to do. I have a 2024 XLE. Didn't like the idea of not having a spare, but also hadn't had a flat in more than a decade, so I begrudgingly accepted it. Of course, I got a flat, likely from going over a pothole, on Christmas day. Sidewall damage, so fix kit was useless. Fortunately it happened while I was close to a family member's home, so could spend the night there. Also fortunately, the nearest Toyota dealer had a tire in stock, and I was able to get on the road again later the next day, after spending nearly as much as it looks like folks are spending on getting an after-market spare and tools. (Toyota roadside service couldn't send a tow sooner than 5 hours after I called the morning of the 26th, so I ended up paying for towing on my own.) So.... is there a consensus here on what's the best option? Would the dealer sell me a suitable spare and tools? Are those of you who've gone with Modern Spare happy with that purchase?

 

Roadside assistance will NOT bring you a tire. I asked, on Christmas night, when I was 2.5 hours from home with a sidewall slit from a pothole. Needless to say, I didn't drive home that night. All they would do would tow me to a dealer or gas station, where the car would be left overnight. Obviously, I declined, and instead drove the short distance back to my brother's home and spent the night.

 

OK, I've read the whole thread now! Not sure exactly how things ended up with what jack adaptor is needed, but I'll get back to those posts later. Basic detail I'd like confirmed right now is whether the part numbers are the same independent of whether a 2023 or 2024. My understanding from this thread is that they are the same, but I'd like to confirm. I have a 2024 XLE. Thanks!

 

Thank you for sharing this. I have been wondering how the center of the cargo floor directly above the spare tire would be supported. I need that space to be solidly supported.

 

One more question: Is the only difference under the deck of the hatch between the AWD and FWD versions of the XLE the presence of the exposed charging cable in the case of the AWD? If someone converted their FWD XLE and happened to take a picture with everything out, I'd appreciate seeing it. Otherwise, I'll wait for another warm day and take mine out to see. Thanks!

(waiting patiently for the moderator to approve my posts)

 

Thanks so much! This looks more practical. I’ll take a look at RobotBastard’s post.

I’m having car color envy. Was thinking early today…if this silver Prius on a QC hold falls thru, maybe I should snag a red one. Still a bit flashy for my circumstances but it sure is beautiful!

 

I just read your posts. Sorry you had to deal with that especially on a holiday. Your incident is why a spare is must in my situation.

2023 and 2024 are the same. From what I understand the only difference with FWD and AWD is the AWD has some components below the cargo area but thankfully they don’t interfere with adding the spare.

I would suggest using the YouTube video that’s posted
several posts above this one. The video addresses the required parts. A few people have saved money by cutting the original styrofoam to fit the spare instead of buying the new OEM foam pieces. Sounds too messy for me.

I think the Modern Tire spare is heavier but someone else can chime in on that and your jack question.

 

For anyone interested, a late 2024 pricing update. Using the best december 2024 discounts (it was 25% off the already discounted online parts prices) that I could find, I was able to get these spare wheel parts for (including sales tax, and also got free shipping on everything):

$54.07 for the 42611-21280 OE toyota prius steel spare wheel rim
$67.70 for the 09105-47020 OE scissor jack w/ crank tool + lug wrench (no bag)
$86.40 for a new Yokohama T145/90D16 donut tire (off ebay)

I didn't get any of the other hardware, as I will be unable to mount the tire under the cargo bed, since I have a prime/phev. But I did get a very simple spare wheel bag off amazon, just to keep the car a bit cleaner during road trips, and the "65cm" version of the bag fits this spare perfectly:
"EKDJKK Car Black Sliver 13-19'',17-22'' Spare Tire Tyre Wheel Cover Bag with Carrying Handles" (search on amazon)
(fyi, when you strap the wheel down during travel, you most definitely want to anchor it by the rim, not by the bag, as the lightweight bag will tear instantly in an accident.)

Weighing the whole spare (after the tire and valve stem installation) got me an actual weight of 28.8 to 29.0 lbs.

Related, anyone know what is the recommended operating pressure for this donut spare? The tire sidewall says a max of 60psi, but I imagine that the optimal tire pressure is a lot lower for a gen5 prius?

 

From page 524 of the Toyota USA 2023 Prius Owner's Manual: 60 psi. (it's always been thus)

 

Thanks.

I gotta say, that toyota recommended psi seems extremely high, given that, while this tire is narrow, it is not that narrow compared to the 195mm OE tires.

Puzzling.

 

Think of it like a bicycle tire? They can quite high pressure spec.

again, it’s always been thus, any car we’ve had over the decades, with the temp spares. Full size spares are per regular, but they’re extinct.

 

Of course, but:
Narrower bicycle tires = higher pressures
Wider bicycle tires = lower pressures
(with my 3" wide bike tires, I run 9 psi !)

If this 145mm spare went on a heavy car with wide tires, yes, it would make sense to go with higher pressures. But this spare is only about 25% narrower than the OE full size tires. And the full size psi is 35-36 psi.

So, just based on a "w.a.g." (wild --s guess), I would think that 50 psi would seem to make more sense for a 145mm wide spare on a gen5. But, I guess I will defer to toyota.

 

And Honda, Mazda, and…
