Undeleting the spare tire from a 4

I tried to cut the foam to allow me to fit the spare tire I saved from my gen3 but it didnt work out so well. It looked like a mess and the spare tire is actually thicker than the foam so the floorboard did not balance. There is a lip in the trunk and the floorboard does not meet the rear seats when folded nor does it meet the back of the car where the hatch latch is. I suspect that the correct foam will push the floorboard up to be in line with everything as it sits around and over the tire.

I ordered all 3 components of foam. When I bought the car I allotted some cash to modifications I was definitely going to do.

The list is as follows

64993-47090
64997-47040
64995-47030

I will report in when I know if this is going to work or now. I cannot imagine the car is different in there from a version with a spare once these parts are added. Will it fit around an oem gen3 tire, that is another question.

 

Ok this is getting really costly but of all the modifications, having a spare and adding it correctly is probably the most mission critical change I can make. I do not want to risk it with a repair kit and I want it all to fit the way it was meant to- This might be the ultimate post on this as I got $4k off msrp and an additional $2.5K in my tradein over KBB I knew I was going to lay out some money and do this come hell or high water- So I will be the test subject.

It is way more parts than the 3 foam pieces
(ordered was ~$500 w/shipping)
64993-47090
64997-47040
64995-47030

Taking the spare out of the equation I am estimating that the online discounted oem price all together will be about $1200

Additional parts that I believe complete the list:

58415-47110-C2 the floorboard
(not currently ordered, ~$200 with an additional ~$100 shipping estimate, list price from dealer is $300- not mission critical yet. I will get this but will hunt around)

(ordered was ~$450 w/shipping)
64730-47240-C2 trunk wall liner
64740-47250-C0 trunk wall liner
51962-47020 the foam retainer clips (x2)
64716-47130-C0 the plastic piece along the lip of the trunk floor
64718-47080-C0 the plastic cover around the trunk latch (plugs into piece above)
81330-58010 the lamp assembly in the trunk wall liner
58338-47010 bracket (this will be interesting the diagrams all show only needing one side for this and no bracket for the other side, might me missing other side in this list)

Believe it or not, ALL these parts have a different part number for non-spare. I am rather surprised from a supply chain point of view that Toyota would do this.

 

Theory on what is going on here:

So by adding the spare and the foam, it is going to raise the floor of the trunk to be in line with the trunk lip (in other words there will not be a lip going into the trunk). It is kind of stupid that prius without tire has a drop in the trunk, with tire is level and in the case of the prime is sticking up a few inches but anyway- So my theory is that this will level out the trunk floor. Essentially the lining of the trunk is molded to support a lower level so there might be gaps or fitment issues along the walls because the foam will come up higher. Around the latch area, while there is a drop molded into the trim now, there is also a lip at the very bottom that is under the floor board. I suspect that this lip will now interfere with the new foam and hence a new piece is needed.

Finally, the seats are angled back the higher up the trunk you go. The floor will be in line with the trunk lip so that is a few inches higher. As a result, the floor board will have less distance getting to the back of the seats. I believe this is the cause of the pressure against the seats some other members have detected. The new floor board will be shorter to fit against the seats and probably a bit wider as the higher up you go the wider the trunk gets side to side.

After really examining the trunk area, this is my best guess at what is going on in there. I can envision how it all fits together and that is why I think I am boxed into getting all these parts if I want it all to work the correct way.

Looks like it could shape up to that
Cutting the foam is a much cheaper alternative i guess. Its all about how far do you want to go. Its a range of just throwing a spare in the back to all out oem fitment.

I was expecting to spend $1000, i told the dealer flat out i had to add $1000 to whatever price he threw at me and actually used it as a bagin point. Its why he let me keep my spare and told me he raised the value of my trade in on the second pass. The high ticket items are really the foam nearly half the cost of this... The wall lining ~$140 a side and the floor piece ~$200 the rest are small odds and ends that add up quickly

 

How big are the gaps on the side of the floor board? This confirms my theory that the spare tire floorboard would be wider but shorter. I placed an order for everything and it was rejected saying the parts have been discontinued. The foam is still on the way and will arrive on Monday. I did place an order for the new floor board ($230) hopefully to close the gaps but I have not been told if it is going to be discontinued too or not. I suspect the first place just did not want to risk selling me everything without a vin.

The trunk liners are different, or at least they are a different part number. There are the black plastic\felt panels that are on the sides of the trunk. Because of this, even with the right floor board there might be fitment issues.

On a side note I am getting so sick of people asking for vins I grabbed a vin off a dealer website for a 3- the spares were just not included on the 4, 4 touring or eco 2

 

warning!! error in part numbers!

The correct part numbers are:

64993-47090
64995-47040
64997-47050

 

It is a pain in the nice person but we all know Toyota wont suddenly start selling them with spares. They will argue that they sold the Prius plugin for years without a spare and no problem found. The tricky thing here is that there is foam for no spare, foam for a compact spare and foam for a fullsize spare. Each version raises the trunk to different level too.... Really hard to figure out what to get in the end. I want the compact spare foam so 64993-47090 is the right part number for the circle center piece.

for the left and right side, the guy at the Toyota dealership told me it is:
64995-47040
64997-47050

I ordered them directly from the dealership in case there is an issue. One is $139 and one is $156 The center is about $260 but I got that online for $185 w/ $20 shipping. I will have the new foam in about 4 days.

 

I will take pictures when this is done. I negotiated keeping the gen3 spare and then it is just a matter of the foam. You might be able to negotiate! There are certain times of the year dealers really really want to sell. I am slightly surprised no one posted pictures to date. No matter, i will do it all including with the updated floor as soon as i get it all.
