    I completed the swap yesterday on my LE. My biggest takeaway is that the deck is now raised by ~3 1/2" compared to the stock height, which causes a host of fitment issues (see pics of screenshot of LE with stock height deck board and the new foam height on each side after the swap). This causes the deck board to "float" on top of the foam pieces, compared to it sitting flush with the side panels before. Now, the flaps at the front of the deck board, if moved back slightly, can bind on the back seats when you return them to the upright position. The deck board is also shaped to fit the shorter foam pieces/side panels, so after the swap, in the front corners near the back seats, the white foam is exposed (see pic). The cargo mat is also shaped to fit the lower foam configuration and match up with the stock side panels, so it doesn't match after the swap. There are two "ears" that now hang over "voids" created by raising the deck board on each side. Another issue, especially if you have a cargo mat, is that the rear cargo hooks are below the level of the mat. You can still access them, but the mat height makes it tricky. In order for the cargo area to function like an LE with a factory equipped spare, new side panels, a new deck board and new cargo mat are required. I think I can live with the ill-fitting pieces. I plan on adding something under the voids on each side so the cargo mat lays flat and possibly getting some fabric to glue over the top corners of the white foam pieces so it doesn't show when the back seats are laid down. I may also use a few Velcro pieces between the bottom of the deck board and foam pieces to help keep the deck board in position. The LE deck trim was easy to remove. First, remove the cargo hooks. Then, pull up on the trim from the bottom to pop the clips out of the body. One thing I wonder about is the additional weight of the spare wheel/tire (which sits off-center) and jack components to the cargo area. Do Priuses with the stock spare tire setup have heavier duty springs to accommodate the extra weight (~35-40 lbs.)? Maybe I'm tripping, but my car seems to now have less clearance between the top of the tire and the wheel well on the passenger side.

    One small addition I might suggest for the Gen 5 Prius "spare tire kit retrofit" (other than the side panels + for the LE) are the tire info labels that go on cars with the stock spare tire setup. The original label inside my driver door shows my car wasn't equipped with a spare, and the spare wheel I purchased didn't come with the max speeds label. Both of these labels are available and cheap if anyone is interested. I added my VIN to Lewis's website and found these labels as an "exact fit" for my car (like all of the other parts I ordered). Part number: 42661-47B00. The higher end cars with 19" wheels will require a different label. Attached is a pic of the parts diagram for the labels.

    Thanks @Hammersmith and everyone else who's provided valuable details on this topic. I finally did my conversion today. Nice to have the peace of mind.

    I hope you didn't order that part number. It's not the right one for what you want.

    Labels for the driver door jam with tires sizes and pressures:
    42661-47B00 - 17" wheels, no spare tire
    42661-47B10 - 19" wheels, no spare tire
    42661-47B20 - 17" wheels, with spare tire
    42661-47B30 - 19" wheels, with spare tire

    Caution Plate for the back - appears to be stuck to the white foam:
    42668-28090

    Caution Sticker for the spare wheel:
    42668-42010

    This is what they approximately look like:

    Also, I don't think you understand how the XLE and LTD come from the factory. There are no side panels. All of us with the higher trims have those voids on either side and our deck boards "float" on the foam boxes. The only differences in that area are that the XLE/LTD deck board is shaped a little different and the carpet mats/cargo liners are rectangles so they don't hang over the edge of the deck board. I'm pretty sure I mentioned a couple times in my first posts that the LE mats/liners weren't compatible and the deck board was iffy.

    This is with the temporary spare.

    Thanks for the heads up on the label part numbers, Hammersmith. I haven't ordered anything yet.

    After looking at some photos and videos over the weekend, I came to the conclusion that the higher trim levels must have the same "problem" as I do now with the deck board floating on the foam pieces, as opposed to laying flush with the side panels in stock form. Thanks for confirming. The only way I could see my problem being resolved would be if Toyota made different side panels that would meet the new deck board height. It sounds like that is just wishful thinking on my part. I definitely caught your warning about the cargo mat and deck board not being a perfect match early on in the thread. I'm going to try making a few tweaks to the current setup to see if I can get it to function a little better. Overall, I'm very pleased with the outcome. Thanks again for all the research you've done for this thread!

    Just a little FYI: Those voids are the perfect size for tool/emergency kits. I have the little Toyota first aid kit velcroed above my battery, and I've got the Toyota emergency kit, a cheap Harbor Freight torque wrench, and a Ryobi bag with an impact wrench, tire inflator, and battery in the other void.

    I've also got a 21mm impact socket, a regular 21mm socket, and the shortest 1/2" extension I could find. I use the regular socket and the extension on the torque wrench, and the impact socket on the impact wrench. The two sockets were just because I got annoyed constantly changing sockets between the two tools, and the extension was because I kept brushing my knuckles(or the wrench) on the fender arch while torquing down the lug nuts during wheel set swaps or tire rotations.

    An FYI on this label: It looks like you might be able to get the one for the LE/SE with the 17" wheels, but the 19" wheel version looks to be a long shot. I just ordered one from my local dealership, but they say it's out of stock and on indefinite backorder. If you think about it, it makes sense. The label is printed with the tire sizes for the 19" wheels plus the spare. But Toyota only uses the 195/50-19 tire on the Prius, and that doesn't come with a spare, so why would they print up any labels for a configuration they don't make?

    Those that have the 17" wheels appear to be okay. Toyota does sell that configuration in Mexico as standard equipment. When I looked up the 19" version at Lewis, it wouldn't let me order it for delivery. But it doesn't give me the same warning for the 17", so it must be available to order. I'm guessing the label for the Mexican Prius is in English and not Spanish(or it's in both).

    The other two labels for the back are available to order because they're not specific to the Prius. They're used in many other Toyotas. One was available next day, and the other was available in about a week. It's about $15 altogether, so I figure what the heck. Might as well be as complete as I can possibly get at this point.




    BTW, thanks for noticing this detail, Ahimsa9.

    Thanks for the suggestions on how to utilize the voids, Hammersmith. I noticed your setup in the photos you provided early. I will likely do something similar if I get the correct cargo mat or will stow smaller items in the voids under the cargo mat. I also want to look into getting the reflectors that were mentioned earlier in the thread, since they are designed to fit in the slot on the right side foam.

    I wasn't aware that the models with the taller wheels weren't available in other markets/countries. My local dealer parts guy mentioned that the parts I was inquiring about were available on Priuses in Guam and Saipan. It's strange that Toyota created part numbers for the tire pressure decals that don't exist. I found the decals you listed for my car at Lewis and popped them in my cart. The total was $9. I'll order them tomorrow and see what I get language wise. Thanks again for getting all of this info together!

    It's a mix. Europe gets both the 17" and 19" wheels, but they only get the PHEV which can't have a spare. Mexico gets the spare, but only gets 17" wheels. US/Canada gets the HEV in 17" and 19", but no spare option. Japan gets everything, but their label is almost certainly in Japanese. So there's no place that has the combination of an English label, 19" wheels, AND a spare tire option.

    I suspect the part number is in the system just in case something changes. Maybe the Mexican market someday gets the 19" wheels. Maybe there'll be a US/Canadian corporate fleet purchase that specifies 19" and the spare. At this point, it's just an image file on a computer somewhere and that costs Toyota nothing.


    Side note, I'm happy for the Guam or Saipan market(I can't remember which). I believe one of them requires a two-tone horn. That's why the Prius has a second threaded hole for a second horn. It made installing the Toyota/Lexus premium horn kit super easy.

    Other market-specific options are the ionic air purifier addition to the A/C system in the South Korean version, and the dual-zone climate controls in the European version. I think it's theoretically possible to upgrade the US-spec cars to add the ionic purification, though I don't think it would be worth the cost/effort to source and install the parts. Sadly, the dual-zone climate system is impossible to add to a US-spec HEV. I think you could add it to a US PHEV, but the costs would be so very high($2.5-$4K). And add another thousand or two on top of that to have a shop do the work.

    Wow, that's all very interesting news. At least Toyota is listening to local markets about providing some of the desired vehicle features.

    As for the spare tire labels, my parts contact at Lewis Toyota said that all of the labels he has handled were in English. He also provided me with some diagrams showing the locations of the decals (highlighted in green). I assume this applies to all models that could be equipped with a spare tire?

    Correct. The 80kmh/50mph decal(5) goes on the wheel itself, and there's a shallow rectangular depression in the foam box where the other decal(4) is supposed to go(I noticed it the other day while getting the rear seat out to replace the seat cover).

    The decal(2) on the door jam will be super easy to spot as it will replace the one that's already there.


    I'm supposed to get #4 and #5 probably late next week, and I'll take a pic once they're installed. I have no idea if I'll ever be able to get #2, though you should be able to get your version easily enough.

    I got two of my three decals in this week and installed them. The third one(driver's door jamb) was the one that was listed as backordered with no date given. Apparently ordering it triggered Toyota to make some, because it's now supposed to arrive in about two weeks.

    Here's a photo of the 100% completed conversion(now with decals! lol). I don't know with absolute certainty if the 80/50 decal was supposed to go on the spare wheel, but it seemed logical given the parts diagram. The two sockets are because I got fed up with constantly swapping between the impact wrench and torque wrench. The extension is for the torque wrench, as I was brushing my knuckles(or sometimes the fender trim) when I was torquing the nuts down.

    If it looks like I rotated the tire so the Yokohama logo is at the top and the valve stem is toward the bottom and easier to access for pressure testing, you'd be correct. lol

    Looks good, but I can't do that on our car, as it is a phev ... :(

    I am curious, what is the red long item on the passenger side of your foam?

    Foldable emergency triangles. Apparently they're required in the EU, so there's a spot for them. I figured why not and ordered three from Toyota. It would also be a good place to store a torque wrench, but I tuck mine just to the left of the foam, partially under the Toyota emergency bag(it's just a cheap Harbor Freight wrench).
