After recently converting my LE to add the spare, I put this together to hopefully save others some time digging through the other threads. Refer to this thread for additional discussion and pictures.

All of the required parts will cost around $650 (including wheel and tire). Additionally, you will need to have the tire mounted at a tire shop ($20-30).

This is a 2-3 hr DIY job if you are handy, however there are a couple of items you'll want to make sure you're comfortable with: seatbelts need to be removed and reinstalled (bolts need to be torqued properly), and some carpet needs to be cut (to install the jack). If you have the dealer install, expect to pay $400+ in labor.

Parts Required

1. Spare Tire Kit
Cost: $260
Part: 51900-08050xx, 51900-08060xx, 51900-08070xx, or 51900-08080xx, xx referring to the trim color - see post #2 for more details

This kit has all required parts, except for the wheel, tire, and some nuts. Includes: Trim panel, trim cover for tire, mounting bracket for tire, jack, jack cover, handles, lug nut wrench, and hardware (see attached photo from the install PDF)

The trim color options are B2, B3, C2, C3. For my base LE, the complete part number was 51900-08050B2. I think that all LE's use the same trim color, but you may want to call your dealer and provide the VIN to confirm. My door sticker says trim color FA10.

2. Jack Kit Nuts
Cost: $4
Part: 90176-06051 (order 4 of these)

Required to bolt the jack holder down to the floor. No idea why these are not included in the kit.

3. Spare Wheel
Cost: ~$260
Part: 42611-0R271

Note this shows unavailable on the official Toyota parts site, so either google around to buy direct from another dealer or ebay.

Other forum members have mentioned previous gen Sienna spare fits in the storage area, however a 3rd gen wheel did not work for me. There was some interference or a different offset preventing the wheel from sitting flush against the mounting hub. If you can find an older spare that does, this will save some dough, but ymmv.

4. Tire
Cost: ~$110
Size: 155/80R17

The stock brand is Falken, but anything will work. IE one option at Tirerack: FK-090 - SIZE: T155/80D17 / $107

Total: $650

When ordering, the easiest route seems to be at parts.toyota.com. Check several dealers in your area. Some charge MSRP ($300 for the kit), some are MSRP in-store, and not all offer local pickup for online. Do your dealer a favor and choose local pickup and not shipping. The box is gigantic.

Tldr, try to find a dealer that sells at discount with local pickup and you should not have any issues.

Install

Tools needed: Basic metric socket set and tools, torque wrench (to cover 30-50 ftlb), trim removal tool

See the attached PDF for instructions. It is pretty easy to follow. There were a couple of obvious items omitted: 2 brackets that hold the middle seat straps need to be removed, and transferring the trim piece in step 13 did not apply to my LE trim.

Overall, it's a fairly straightforward install. Cost-wise, the kit itself is actually a fair price considering what's included. Wheel+tire+mounting is actually the biggest expense at around $400. So, should you have the luxury of adding the $75 option from the factory, do it! (Of course, most did not have a choice)

Thanks for posting! I spent an hour with the parts guys at my local dealer on this two days ago, so here’s some supplemental info that may be helpful. There are actually four part numbers -

51900-08050xx, 51900-08060, 08070 and 08080 depending on what combination of rear entertainment and rear shades you have. This is detailed in PANT 2020-060 rev 2 which someone awesome posted in that other thread you linked.

Another potential source of confusion is the colors (B2,B3,C2,C3) - in that PANT bulletin they are referenced as cool gray, warm gray, fromage and light gray, which don’t correspond to the actual interior color that your VIN decodes to. The parts guys at my local dealer knew which one to order but YMMV.

Finally the spare rim and tire are quite expensive from the dealer - others have had success with aftermarket parts and spares from older Siennas sourced from junkyards.

Thanks! Updated the original post. I picked up the wheel at Oem Parts Source.. $265 shipped, they seemed to have it in stock and shipped quickly (appears to just be a group of dealers re-selling online). The wheel is tough to find on eBay / junkyards. Beware that there is a Rav4 spare that looks exactly the same but is 18" and not 17".

Just finished the conversion and wanted to share a couple notes:

1.When picking the part,“rear shade” does not mean second row shade, but a small THIRD row shade for the small triangular (ok polygonal) window in the third row (see picture). My XLE plus has second row shades but did not come with third row shades. I thought it meant the second row shade so ordered the part with shade (ends in 080) and now have a useless little third row shade on the LH side (useless because there’s nothing up top to secure it to).

2. You lose a cup holder and some shoulder room in the third row - as a larger dude I can no longer sit comfortably in the far left third row seat. This is irrelevant for my use case as a kid or small adult will always be back there if it’s occupied.

3. If you have the factory rubber floor mat in the trunk you will have to trim that too when you cut through the carpet to mount the jack. I don’t care because I have emergency kit stowed in the Toyota containers that sit flush with the space so it’s all covered anyway.

4. the Toyota instructions have errors in them - mostly in the reassembly instructions. For example they neglect to instruct you to reattach the second row seat belt for the 8-passenger model, so i used the same torque spec for the third row belt. Would be slightly more comfortable if I had the “official” torque spec there as I believe those bolts are carefully designed to behave in specific ways in a crash but I’m probably just overthinking it, I’m sure the dealership just uses an air wrench on them.

5. This is not a hard install if you carefully follow instructions, only finicky bit was the cargo net hook which was a pain to get out.

6. dealer wouldn’t ship, had to pick up in person but the giant box fits fine in our equally giant Siennas :)

You did an excellent job, for the curtain all you need are the hangers PN 65983-08030 although they don't come with an adhesive.

I just did the conversion and have two items of note.

1) The instructions call for using a 21 mm socket to tighten the lug nuts. That is the same size as the lug wrench, so no need to buy a socket if you do not have one.
2) The kit came with three bolts to mount the spare tire bracket to the car. My 2022 XLE only has one bolt hole. The remaining mounting points were three studs on the car. I had to buy three (you could get away with two) 10 mm x 1.25 nuts to complete the install.[I just reread the instructions. They say the kit contains 1 bolt and three nuts. That was not the case for me.]

SUPER DISAPPOINTED! I just came back from my local Toyota dealership and the Parts guy just wasn’t willing to search and when he did, it came out to be $1495 for the Carrier. I insisted the last part should be either: B2, B3, C2, or C3. I said i have Platinum Sienna with Rear Entertainment and Rear 2/3rd row shade but the guy was just not interested.

So this is the part he pulled from comp after he enter my last 4 VIN number:
51900-09080-C0

I don’t even know why i bothered to get labor cost…. The service guys didnt know and had to wait for a mechanic. Talked to the mechanic and he said so it’s probably I involved removing the rear seats…. The carpet…

Thank you for the detailed instruction.
Could you please let know what are the two following parts for?
42611-0R271 Spare, Wheel Disc
90176-06051 Nut, Cap
Thanks
42611-0r271 is the actual spare wheel (without tire). the kit doesn't come with the spare so you either need to get the wheel and get a tire to mount or try to find a used one
you don't really need the nut cap

So I ordered the carrier assembly from a local Toyota dealer and after pulling the original trim out to install the assembly I found out that the cup holder was missing. I figured this was an honest mistake made by Toyota so I went ahead and installed it without it.
Called them today to see if they could send me the cup holder but they are telling me that it's not part of the assembly! I was pretty incredulous so I asked him to confirm that this is so and he went and verified it.
I think they are full of it but what could I do? So if anyone is reading this, I would call first to ask specifically if the cup holder is included. Orderring the cup holder separate is about $50. I don't see any mention of anyone not getting the cup holder here or adding it to the parts ordered list so buyer beware.

Had my parts guy ordered for me 51900-08060-b2 (2023 xle 8p light gray interior with RES). I quickly glanced at it at the dealership to confirm color before driving home but fail to realize it did NOT have the headphone jack and volume part punched out. Luckily the plastic cuts like butter with a dremel and sharp razor to trim accurately. Thankfully, it also had an outline on it where the headphone jack should be so I can follow the cutout. 25 mins later, looks oem again. Obviously I could have took it back and reordered but didn’t think it was worth the hassle of lugging a big piece and waiting on new one. Plus I trusted my average diy skills …lol (ymmv). But if you have a RES, make sure yours is there too before going home (if doing a dealer pickup).

Greetings! I'm picking up a 2025 Platinum with black interior in a few days. Parts department was only able to tell me that the full $1,500+ kit (51900-08071-C5) matched the 2025. That's really pricy and comes with the OEM spare tire - and I'd rather buy a Modern Spare.

I'd like to order part 51900-08070-XX, but I have no idea what trim code matches a '25 with black interior.

Anyone else order for a black interior and can tell me their trim code? Any reason to think the '24 kit won't work with a '25 (which is what the online parts finders and the dealer tried to suggest)?

Last 4 of VIN: B847

UPDATE
Spoke with another dealer's parts department. The 2025 VINs aren't yet loading in their database for matching to trim colors and the online parts finders are doing weird things (like defaulting to a trim color that may not match). 2025 has at least one new trim color. The kits without the tire "Spare Wheel Carrier Assembly" that are much better priced, likely will exist but are also not yet loaded/orderable. They might need to be ordered peicemeal, but until the 2025 gets fully updated for ordering parts - we won't know everything.

ADVICE: Want the spare tire kit for a 2025? Probably best to wait till this all gets sorted, especially if you are going to pay for shipping.

I have a 2025 with gray interior, and have the same problem finding out which grey would work from prior years. But i think your advice is sound. Just wait until Toyota updates their database, thanks.
