Upgrading to a full size spare wheel

Not sure what trim levels are offered in the US, but the 3.5L V6 here only has a donut while the non-hybrid/2.5L Ascent models get a full size spare.

I want to replace the donut with a full size but I know the existing trunk floor storage box/foam piece that holds the tyre iron and scissor jack won't fit flush with a full size wheel.

If someone has this model and is able to quickly check, the part number is on the underside of that foam piece. Donut foam part number seems to be 64779-33240, at least for japan built vehicles.

Thanks in advance

Update: changed thread title, found out the part numbers and have done the swap to a full size spare

I wish...if you have an aussie built toyota (VIN: 6T1) good luck finding part numbers. Foreign numbers will work since most of the time it's just locally manufactured parts (I've noticed they tend to end in -YCXXX) but otherwise we're a black hole when it comes to identifying parts. The really annoying thing is that the Aurion/ACV36 models which still built in Australia will show up in foreign EPCs, while everything else basically never existed. Of course since we never exported significant numbers of our vehicles to overseas markets (besides surplus gen 3 camrys going to the middle east) it makes no sense to publish AU parts numbers internationally, but still...wouldn't it be nice.

It's almost 7 PM on a sunday here so dealerships are closed, thankfully I have next week off so maybe if they're open on Monday I'll check it out, hell I might just rock up and ask for a tour of any showroom models they have and take a note of the part numbers lmao. Otherwise it'll have to be the day after - here if a public holiday falls on a weekend, it gets carried over to the next week.

One small benefit of our auto industry dying off is that since we get japan built cars, we can start using foreign EPCs when they become available for newer year vehicles at least.

A multitude of reasons:
  • boxing day public holiday (pretty much all wreckers are closed either today, or rest of the year...the one time I decide to take time off)
  • wrecked recent model vehicles seem to vanish into a black hole/the aether because I have yet to see recent year model vehicles of any sort at the self-serve wreckers I've been to so far
  • the decent wrecking yards that haven't been molested by animals that just tear/cut things off, damaging other stuff in the process, are at least an hour's drive away from where I live
  • I'm lazy, therefore I will expend the least amount of effort for the same outcome where possible. If asking around here saves me driving or calling up places then that is laziness doing its job as intended.
To top it off, apparently the government is increasingly becoming unfavourable with junkyards due to what would be the equivalent of your OSHA regulations and there are rumours that they're starting to crack down on these kinds of places that allow customers to freely enter with no safety gear etc.

When it comes to this sort of thing the US is almost a haven, the first time I heard of 24 hour auto parts stores...you guys have it wonderful over there, don't ever let it change.

Sweet found the part numbers!
64779-33250 for the center foam tray


64429-33020 for the surrounding plastic part


Dealership was about as useful as tits on a bull, so today I went to a used car lot and asked the guy if he could pop open the boot and he was happy to help out.

Some things worth noting:
I'm not sure if the carpet tray trim thingy that sits on top of the existing foam tray for the donut will actually fit flush though - the placement of the plastic lifting tab and hook is off center with donut spares...(update: this part's number is 64770-33140-C1 - I've no idea what colour codes are what, I'm guessing a black felt board is -C1 or something) If your lifting hook is off-center, it will NOT sit flat with the plastic ring (64429-33020). You'll need to order part 64770-33160.


That plastic hook sits inside the below squared area for donut foam pieces:


...while the full size spare has that piece sitting in the middle as shown below: (part 64770-33160)


And if you look at the second image (part 64429-33020) you'll notice at the six o'clock position, a notch/indent in the perimeter of the center hole - this together with the space in the center foam piece (first image, at 9/10 o'clock position) allows for the plastic hook to sit flush. Either way, I'm ordering both the plastic ring and foam tray and will try it out when they arrive. Managed to get the part number for the cover board that has the hook in the center - 64770-33160.

Another update: part number for 19 inch V6 rims of the below design are 42611-33D20 if outside of the US; otherwise it's 42611-06E20.

If wanting to install a TPMS valve, 42607-60010 is what you want. Unknown if other TPMS valves will work or not. 90942-05009/90080-94031 for an ordinary, non TPMS valve - I thought cars made after a certain year were mandated to have TPMS by law but turns out over here that doesn't seem to be the case, at least since my 2018 camry didn't come with any such system. If anyone wants a brand-spanking new, unused TPMS sensor let me know...

The spare wheel carrier for the donut will be much longer - replace this with 51931-22040 - this version will be short enough to keep the new wheel in place in the trunk. Cost me about AU$22.55 at the dealer, you can get it for cheaper off sites like amayama.

Aww yiss finally got around to getting the tyre fitted onto the rim...the wheel fits perfectly, and it actually had room to spare around the perimeter despite it being a 235/40/R19 tyre.

The original setup, note the floorboard (referred to within parts catalogues as "cover assembly") with its offset hook set on the weatherstrip:


Donut spare:


Spare wheel bay:


Parts required:

Center foam piece or "spare wheel tray"/tool tray and the clamp/"spare wheel carrier"/center fastener (64779-33250 and 51931-22040 respectively):

The original spare wheel carrier for the donut is on the top, as you can see above, it is longer than the one for a full size spare and thus will not hold down the wheel. On a side note, does anyone know what tools fit in the various slots/cutouts in the tool tray? There's space for the jack, towing hook and tire iron but otherwise that's the only ones I can think of.

The surrounding plastic piece or "luggage box"/spare tyre cover 64429-33020:


64770-33160 for the cover assembly/luggage floor cover, bottom and top respectively:
rainbows make me cry

In the left picture, three spacers towards the back are visible, these provide the clearance for the board to sit properly over the luggage box.

And a full size spare wheel, best to get one from a junkyard or something. I bought everything brand new because we don't have any wreckers here that have late model camrys, not even ones that are statutory writeoffs. Maybe they're too valuable for parts to let plebs like us get our grubby little fingers on them at self-serve yards.

Aftermath

Fortunately doing this is simply a matter of swapping out existing parts, no tools required. With everything in place, here's what it looks like:

Don't mind the specks in the floorboard; that's just grass lol.

And with the floor liner in place, the whole thing actually looks rather slick. But more importantly, you can carry things like a lawnmower without scuffing the floor:


Got a better, brighter photo this time. Full size, 19 inch spare, with the new carrier holding it down. The original carrier had the bolt head visible in the top black plastic bit that you grip but besides that and the length of the carrier, they are identical. Interestingly, the diameter of the entire wheel is actually a bit smaller than the donut spare - the tread doesn't touch the walls of the spare wheel bay at all, but it's probably not easy to see here:


Better, brighter photo here too. Notice the curve of the cover assembly hanging off the weatherstrip - this isn't just due to gravity, but is also the way the board was created so as to be able to clear the top of the luggage box (working together with the three spacers seen previously to make it sit properly over everything). Everything in place. Note the jack handle now being placed in the plastic cover, towards the right:


Buying all this stuff brand spanking new, the whole endeavour probably cost me about 900 AUD but I kinda did it just because I could, and also because in the future it'd be one less thing to worry about on a long road trip if a tyre should pop. It might also increase the resale value of the vehicle, but that's just a fringe benefit for me as I don't intend to sell it any time soon - I went through all this mostly just because I could lol. Another benefit of a full size spare is being able to include it in tyre rotations - you can then go 20% longer between tyre changes. If you need a TPMS sensor this may bump the total cost to 1 grand AUD.

The biggest expenses were the alloy and tyre. You could easily get a used wheel for far cheaper from a wrecking yard or something. Assuming the 17/18 inch wheels and their tyres allow for an identical outer diameter as the 19 inch wheels, you could probably just scavenge those instead if you can't get your hands on a 19" wheel.

The foam tool tray was about 40 AUD for me but I got it at cost price so expect to pay more if not buying from a junkyard. Surrounding plastic piece/spare tyre cover was about 106 AUD, while the spare wheel carrier/clamp was around 25 bucks from the dealership because I was impatient. Alloy rim was about 487 AUD cost price, expect to pay much more for a brand new one. Getting same model tyres that the car originally came with (Dunlop SP Sport Maxx 050) would've cost me 370 AUD, but the tyre shop I used let customers price match and I was able to drop the price down a bit to 305 even after the initial price match the shop gave me. Basically, if you want to save cash, hit the junkyard or make friends with someone who works at Toyota, else fork out the cash at the dealership or buy from one of those third party sites that sell OEM parts for cheaper.

Also note that if getting a full size spare, cargo capacity is slightly reduced by 31 litres from 524 L to 493 L. Not sure if that's significant enough to impact usual grocery getting, but in practicality it just raises the central floor a little bit (about 1-2 inches).

For anyone else doing the same thing, please note that the part number for the shorter clamp/"spare wheel carrier"/center fastener is actually 51931-22040 (the one listed in this post, 90080-94031, is a valve). Just got mine for $26.47, there’s stock shipping from Sydney.

Additionally for anyone with a XV80 Camry and wondering if the parts fit: yes but 64770-33160 (the trapezoidal raised boot floor) has a slightly different shape (you could cut it to fit perfectly) so while it’s not perfect it is good enough to not be noticeable with a boot liner on top.

Whelp, looks like I hit the image limit - if you want a trunk liner, toyota has a raised boot liner - PZQ20-33310:

The little bump is for the lifting hook on the floorboard/cover assembly.

Tyre rotations for full size spares:
325234

Owner manual is available online from Toyota's website, US spec camry manuals don't have info about the full size spare since that was never an option there to begin with. All I did was just clear up part of the not for reproduction overlay for better clarity. This was obtained from toyotamanuals.com.au.

Out of curiosity - have you needed to use the full size spare in the 4 years you've had it in the trunk?

Great work, thanks for the part numbers and such. I typically just throw one of my winter tire/rims in the trunk if I go on a road trip so I have a full size extra IF needed... your way is so much easier lol

Lol nope. At least, not in the traditional sense. I do rotate my tyres every oil change however, and with the price of 235/40R19 tyres, it means I can go longer before having to replace them.
I haven't taken it on shitty country back roads though, it's all been city driving so far. Neither have I come across nails or any punctures so far, and the potholes that I do come across, the wheels have somehow managed to survive, despite one incident resulting in smacking the suspension so hard that the center console screen rebooted itself.

This weekend though I'm going to buy some 16 inch steelies off a wrecked XV50 camry. I hate this trend of grocery getters fitted with rubber bands, the 215/60R16s I'm replacing them with will be significantly comfier. Wanted to go 205/65R16s as that's much closer to the 19" wheel diameters but the particular model tyre I'm after isn't available in that size.
