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

What is the color code for a black interior XSE 25th Anniversary Edition? I've been trying to figure it out before ordering.

Did you find the part number for the 25AE spare kit?

Yes and that's thanks to member LEXHYBRID who did the conversion on his. Part number is: 51900-08050-C3
