OEM spare tire install

Normally I'd say you'd be better off asking this in the Gen4 forum, but you caught me with some spare subscription time left on the parts catalogue, so here you go. This should work for any FWD Gen4 HEV (no AWD, no Prime).

Absolutely needed:

Code:

T125/70 D17    Tire                    $80-$125
42611-47631    Wheel(17x4)             $ 80.72
51931-47030    Hold Down Bolt          $ 11.25
64993-47110    Spare Tire Carrier      $ 57.45
Subtotal: $119.54 + tire

I would absolutely get a new tire. On TireRack, a Falken was $80.70, a Yokohama was $114.45, and a Continental was $125.91. I tend to go Yokohama just because my OCD likes a Japanese tire in a Japanese car(lol), but I doubt there's any real difference.

The carrier is the foam pad that lays on the sheet metal and holds the tire. I personally consider it a needed part because it lines everything up and keeps everything stable. You might be able to find the carrier and wheel cheaper at a salvage yard.

The reason the individual prices don't add up to the subtotal is because there's currently a 20% off sale at many official Toyota online parts dealerships through tomorrow(Monday) night. If you order before tomorrow at midnight(PST), you will pay the subtotal listed; if you order afterward, you will pay the individual prices. I'm showing prices from Lewis Toyota out of Topeka, KS(autoparts.lewistoyota.com). You might also have a dealership closer to you that also normally sells at 31% or more off MSRP.

Now for the extra(and expensive) stuff to make it perfect:

Code:

64993-47090    Deck Floor Box, Center  $248.31
64997-47060    Deck Floor Box, LH      $169.63
64995-47050    Deck Floor Box, RH      $169.92
64716-47130-C0    Deck Trim Cover         $ 68.22
Total: $644.40 + tire

The first box is the one that goes onto and around the tire and creates a flat floor. The RH and LH boxes go on either side of the tire. The trim cover may or may not be needed; it depends on whether your car originally came with a compact spare. The total includes the parts from the prior list. If you don't already have these parts, I would absolutely try to find them at a local salvage yard due to the cost for brand new ones. You could also try fabricating your own pieces out of rigid foam.

With all these parts, you should have an install that would be indistinguishable from a factory install. Exactly how far you want to go is up to you, your wallet, and your skills and time.


edit: Oh and if you don't have the cargo floor board, it's:
58415-47110-C2 - Rear Floor Board #1 - $282.42 without the 20% off.

Obviously I'd try to find a used one of that as well.

 

Oh shit, I'm sorry. I didn't understand that section of the parts diagram correctly. It's one of the issues with dealing with everything translated from Japanese. Plus my unfamiliarity with the gen4(I've owned gen3 and gen5).

Apparently the gen4 was available in some markets with either a compact spare or a full sized spare. What you've got there is an insert that goes into a full size wheel. In the parts diagram it's listed as w/Ground Tire. I guess Ground Tire is what Toyota calls a full size wheel & tire.

Without a scale reference in the diagram, I thought it was much smaller than it actually is and would go underneath the wheel. (I was thinking it was maybe four to six inches wide and only a couple inches high.)


You've got two options at this point:

1. Continue with the compact spare.
- If you go this route, try and return the 64993-47110 carrier for a refund or exchange it with 64993-47090. I believe the reason the bolt is bottomed out is because the tire hasn't been installed yet. Once the tire is on, it will raise the wheel high enough that the bolt should be able to snug up. The other carrier(64993-47090) will go over the top of the compact spare to create a flat floor.

2. Go with a full sized spare.
- If you go this route, try and return or sell the compact spare and find a used wheel to match the other four on the car. (Or did you say the previous owner already was using a full sized spare?) The big black foam block will set inside the upside down wheel to give a flat surface for the cargo floor.


Again, I'm really sorry for the bad info. I had no idea the gen4 was ever offered with a full sized spare.

 

An addendum to my previous post:


I dug into the parts list again, and I don't think I can recommend going with a full size spare if you want to end up with a finished look. In your photos, you haven't shown any of the foam pieces that would normally go in the back and surround the spare. Do you still have those or did the previous owner discard them?

In any case, now that I know what I'm looking for, I can see that there are quite a few parts different between the compact spare installation and the full size spare installation. I have no idea how different the parts are from each other and which are compatible with which.


These are all the parts that are different between the two types of installs:

You're welcome. Again, sorry for the error.

I'm probably wrong again(lol), but I now believe there were a total of four different configurations of the cargo area in the gen4 Prius(plus a fifth configuration for the Prius Prime). I grabbed images from the part diagram to illustrate the four options. Hopefully this will help you figure out which configurations and parts you already have.



1. FWD w/ No Spare - The gen4 Eco trim had this. Maybe others as well?





All other versions had the same surrounding parts, it was just the piece in the middle that differed.





2. FWD w/ Compact Spare Insert (goes over the compact spare)



3. FWD w/ Full Sized Spare (goes into the spare wheel)



4. AWD - No Spare Available (goes where the tire normally would)

 

1. Deck boards: There are three different deck board options for the gen5.
- 58410-47030-C1 - This is the deck board that comes in the LE
- 58410-47060-C1 - This is the deck board that comes in every other Prius and Prius Prime
- 58410-47040-C1 - This is the deck board meant to be used with a spare tire installation

Differences:
- The difference between -30 and -60 is the placement of the crease(s) where the cargo area meets the rear seat backs. The -30(LE) has two creases; one where the deck board meets the seat, and one where the board folds over when the rear seats are folded down. Because all the other trims have a higher deck floor that is flush with the folded seats, the -60 only has one crease for when the rear seats are folded up. This means that the LE board should work in the high deck trims, but the -60 probably wouldn't work in an LE. But I've never tested this or seen it tested so I can't know for certain. Looking at the part images, I think the low deck board might also be a bit wider. That would mean you'd have a little overhang on each side after a conversion.

Low Floor Deck Board (58410-47030-C1):



High Floor Deck Board (58410-47040-C1 and 58410-47060-C1):


- The difference between -60 and -40 is four little foam blocks glued to the underside of the deck board that rest against the tire to give a little extra support to the board.

Takeaway: If someone's already got -60 deck board, there's no reason to waste money on a -40(like I did). Just get some dense rubber or foam blocks and glue them to the -60 board. If you've got a -30 deck board, I would first try gluing the same blocks to the bottom and see how the board works. It might work perfectly fine, or that extra crease might cause it to hang up every time you fold and/or raise the rear seats. If it's troublesome, I'd look at the price($230) and decide whether eliminating that hassle is worth the money or not. That's a personal decision with no right or wrong answer.

2. Carpet mat:
- You go with a mat, liner, or neither depending on your preference. You don't use both a mat and liner.

3. Cargo liner:
- Will your current liner still work? I don't completely know. It depends on whether your current liner is a big rectangle or if it has "wings" on either side. The correct liner for a high deck floor is a big rectangle. If you try to use one with "wings" after the conversion, those wings will flop down because the main floor will now be a few inches higher than the little areas behind the wheel wells. My problem is that I know there are separate carpet mats for the high and low floors, but I don't know if there's a separate cargo liner for the LE or if all Priuses get the same rectangular liner. If yours is a rectangle, you're good to go. If yours has wings, you'll need to decide if you can live with the floppy sides or if you'll want to order PT908-47235-20 for $100. I think at least one owner decided to just stick stuff in those pockets for the liner wings to rest on. Again, personal choice.

4: Jack price:
- Absolutely no idea why the price differences are so weird. As far as I can tell, all the different kits come with the same tools; the only difference is whether it comes with a bag and what kind of bag it comes with. I'd advise just getting the cheapest of the three options. Especially since you're not going to use the bag anyway since every tool has its own space in the foam blocks.
