2023 - Prius or Prime - spare tire?

Finally the lowest 2" layer, it supports the middle layer.
In many places it needs some additional foam spacers below it to contact the floor pan for support.

And here it installed in the car

 

Some additional pictures.

Upside down view of the five sections stacked.

Cover and middle, then all three layers.


And here's how much foam remained from the 4'x8' sheet.


And the factory foam now longer being used


And finally the factory floor and floor mat installed over the cover layer.

 

Don't forget to put a bolt in the middle so that spare tire isn't a projectile in a frontal collision

 

Thanks for the diagrams, I must have missed them. Looking forward to seeing your final results (and cost), and detailed pictures of what the "if equipped" configuration really looks like.

 

It has one, the one that came with the spare from the Toyota C-HR fit just fine.

 

From @Hammersmith 's thread here: OEM spare tire install | PriusChat we know there is a different floor/deck board.

And you can see it here:

It's got some spacers stuck on to be supported by the wheel/tyre, and maybe it's thicker.

 

If those blocks are the only difference, I'm going to be annoyed I didn't see this video before ordering. lol

I assumed the difference is pretty minor, but I also assumed the difference is a lot more sophisticated than just some foam blocks glued to the bottom.


And before anyone says anything, the graphic for the spare tire size is wrong. You can read the real size on the tire itself(145/90/16), and it matches the manual.

 

Something I find mildly humorous in that video is that they put the wrong cargo mat in that car. That mat is meant to only go in the low-floor models like the LE in the US. While the Mexican Prius shown in the video is basically an LE in most ways, the spare tire option gives it a high-floor, so it should have gotten the same rectangular mat that comes with the XLE, LTD, and all the Primes.

 

Good spot - I managed to pay attention to the car, but wasn't paying full attention to the text.

I thought you'd managed to restrain yourself on your the "full" solution

 

I did until I saw the Japan price for the board was only about $60. And the board isn't going to make the shipping box all that much bigger because the foam pad for the spare is almost the same size. At that point, I figured what the heck.

I also just noticed that Mexico gets the auto-folding side mirrors with the turn signal indicators.

 

Hey @Hammersmith,

Appreciate all the leg work you've done on tracking down the spare tire/trunk parts for a 2023 prius LE. Back in 2023 - right after the car came out - my wife was one of the unlucky ones who blew a tire in the first month...before they started circulating the correct sized TOYO tires into the market. It was a nightmare. Luckily got a platinum warranty out of it.

Anyway, I'm new to this forum, so I therefore couldn't DM you...but I have been waiting for the final retrofit parts to be perfected and available from the dealers.

So...I'm wondering if you could link me to the most up to date list and part numbers to retrofit the trunk of a 2023 LE - to fit a spare tire in there. I've got a jack, but that's it.

 

(I've really got to get off my butt and create the 2.0 version of that thread with an included F.A.Q. - lol)

What parts you need depend on how perfect you want it to be and how much you're willing to spend. The LE has a different bottom hatch trim. To do a perfect conversion, you'd need to replace it. But you can probably get by without it if you wish. You'd just need to use some zip ties to secure the foam boxes to the trim piece instead of the regular push connectors.

The other thing is the deck board. Because the standard LE has a lower floor, the LE deck board has fold points in different places(plus it has one extra fold point). The deck board for the spare tire also has four foam blocks glued to the bottom to give some additional support; the LE deck board lacks those. The blocks are easy enough to add, but the fold points are built into the board. While I don't have any personal experience with trying to use an LE board with a spare tire, I expect it would function adequately after adding support blocks, though it might not behave perfectly when raising and lowering the rear seats. But no guarantees. I think there were one or two LE owners that shared their experiences, but I don't remember which of the dozen spare tire threads they were in.

Finally, you'll need a different cargo mat/liner if you want it to fit properly. The ones for the LE will have flaps that hang over once the conversion is finished.


Core Parts List:
145/90-16 tire - buy from TireRack or some other tire store

64778-47090 - Protector, Spare Wheel - supports, centers, and levels the wheel
51931-10040 - Carrier, Spare Wheel - bolt that secures the wheel to the floor
64997-47100 - Box, Deck Floor, LH - white foam tray that surrounds the spare
64995-47080 - Box, Deck Floor, RH - ditto
$395.76 + tire - price if purchased in next 4.5 days

Optional(if AWD):
51978-47010 - Protector, Spare Wheel - covers and protects the HV connection to the AWD motor
90178-A0132 - Nut - need 3
$31.25 - price if purchased in next 4.5 days

Optional(for LE):
64716-47170-C0 - Cover, Deck Trim, Rear - the replacement hatch trim piece
58410-47040-C1 - Board Assy, Deck, Spare Tire - the replacement deck board

So your price(if ordered in the next 4.5 days) could be anything from around $500(core parts plus a $100 tire) up to almost $900 if you go all the way(core + tire + AWD + both LE parts + mat/liner).

I use autoparts.lewistoyota.com, but you can try to find another 31%-off dealer on autoparts.toyota.com closer to you and still get the additional 20%-off 4th of July sale plus free shipping. I would just suggest to find one that's not in your home state. If the dealership is in the same state as the shipping address, the software will automatically add sales tax. If the address is in a different state, it doesn't.
