OEM spare tire install

Thanks for the reply Blackat, I appreciate the help! I'll be at Toyota dealer tomorrow, so will do!

 

WOW @Hammersmith, terrific info, thanks so much! I'm definitely going to do the "absolutely needed" list, I'm in Florida, so going to try and find an official Toyota online parts dealer 20%+ off closer to me, or maybe I'll just see what shipping is from Lewis. I'll study your info and attachments and make sure I order the right stuff. Thanks again, super helpful!

 

Question: So I know that when I acquire a temporary/compact spare wheel and tire, that the tire will need to be mounted on the wheel. Anybody know if these are typically balanced also, that is, put on a wheel balancing machine, spin test, and add balancing weights if necessary?

 

3rd Gen spare specs will work too. IIRC it’s 16” diameter, and the outside diameter of spare is significantly closer to the stock 195/65R15 (common to both Gen 3 and 4).

info is in the 3rd Gen owners manual, pdf available for download at Toyota Tech Info website, in “manuals” tab. To quickly get to tire spec pages search for “195/65R15”.

A salvage Gen 3 temp spare on rim will be getting long in the tooth. That said, ours is about as old as they get (our ‘10 has build-date August 2009), but still “looks” like new.

 

Thanks to all who have posted the info on this...I was told by the salesman that the car did come with a compact spare, and only discovered later that it didn't. Mine is the front drive limited model.

I thought I'd just order the spare and other from Toyota, but our local dealer parts dept. was so slow and unhelpful, I ended up doing it a bit differently. Ordered a Modern spare with jack, very nice and came quicker than waiting for Toyota. While waiting for the foam parts from Toyota, I decided to hack out my existing foam to use temporarily. I got an M8-200mm bolt and fender washer from our local hardware store, and made up a plate large enough to hold it down via the center hole. This actually worked out nicer than I expected.

When the dealer's foam parts arrived, we fumbled with them for some time...I think he got the wrong one for under the tire. Then we put in the foam, and I saw that I'd lose all those nice little compartments that were left on the original foam...the parts guy himself said I was better of with what I already had, and I agreed. Had I known this, I'd have probably used a heated sharp knife to do a little neater job on the foam, but it still works just fine. The Modern spare sits on the floor with only the rubber touching, but I added a small piece of trimmed carpet for underneath it anyway (not shown in picture).

The compartments that are left give me plenty of room for a small lithium battery rechargeable compressor from Amazon, tire plug kit, and plenty left over for other stuff. The jack straps nicely to the modern spare with the included strap...I may move it to the large compartment but not sure. The junk compressor/sealer that Toyota included doesn't interest me.

The only downside was the floor lacking the support of the original foam, where the spare tire now sat. I had a large kneeling pad from Home Depot, and set on top of the tire it works great. It supports the floor decently, and I've got a nice kneeling pad if I need it for whatever.

So with the spare and jack (about $480 with shipping, I spent maybe about $30 additional and ended up with a better system than if I'd bought all of it from Toyota. Not sure how this will work with the other models or the AWD ones with boxes or wiring, but for mine I'm happy with it.

 

There are heated styrofoam cutters. Will those work with ABS foam?

 

They should work with whatever this foam consists of. My soldering gun melts through it just fine, I may use it to dress up the cut edges when I get a round tuit.

 

I used a drywall saw. Fairly clean cuts

 

A styrofoam cutter is a heated wire. If it works, that would mean cleaner curved cuts.

 

True. I just used what I had and it worked well

 

Thanks again @Hammersmith , I jumped on the sale you mentioned and ordered the "Absolutely needed" parts above from Lewis Toyota, $119.54 shipped to my door. Also got a Yokohama Y870C T125/70D17 98M tire from Tire Rack, haven't had it mounted yet but that's next week's project.

I am having one issue though, if you (or anyone else!) could offer any suggestions.....I consider myself pretty handy, but for the life of me, I can't figure out what to do with the 64993-47110 Spare Tire Carrier! I've attached 3 photos of it (bottom,top,side), if you look at the bottom/side photos you'll see there are some felt pads attached to the foam, also the bottom photo shows the part number. This Carrier piece is about 7.25 inches tall. Is this Carrier piece the correct part? If found this, same part #, but looks like a different part:
64993-47110 Genuine Toyota Box, Deck Floor, Rear (toyotapartsdeal.com)

If what I received for the Carrier is the correct part, does it go below or above the wheel?

I've also attached a photo of the wheel with front/outside facing down sitting on floor, with the Hold Down Bolt threaded in all the way (bottomed out), and there is still about a 1 inch gap between the plastic head of the Hold Down Bolt and the wheel. If the wheel is front/outside facing up, the bolt is not long enough to thread in. (A photo of the OEM threaded floor bracket is in my post above.)

Am I doing something wrong? Did I receive the wrong part for the foam Carrier? Is the Carrier supposed to go under the wheel and raise it up off the floor, so that the Hold Down Bolt will be able to tighten down onto the wheel? If that's the case, seems like the Carrier height will have to be cut down (bolt not long enough with Carrier as-is). I'm probably just doing something dumb! Any suggestions about what to do to make this work for my Daughter's Prius would be greatly appreciated! Thanks!

 

Thanks @Hammersmith , no problem at all! I really appreciate you taking the time to help in the first place! I agree about the parts diagram, quite confusing for me! And ya, when I read "ground tire", I was like Wth?? LOL

But I think luck is on my side.....my daughters were fortunate to both inherit used Priuses (Prii??, LOL) from their grandfather, a 2016 when he decided to get a new 2019 and pass down the 2016, and the 2019 when he unexpectedly passed away from covid in 2022. At some point in time, he acquired a full sized spare wheel/tire, but that's it, he did not get any mounting hardware or foam blocks etc. for it.

The 2019 will stay local, and I could see putting the full sized spare in occasionally for long trips (otherwise full sized spare will stay in garage), so I'll try the insert that goes into a full size wheel (64993-47110 carrier) with the full sized spare and see how that works, sounds like I may be able to re-purpose for the 2019.

I'm putting the compact spare in the 2016, I'll get the tire installed and then see if that bolt will tighten up. Then I can watch for another sale to get the 64993-47090 carrier to fit over.

So no problem! Thanks again for all of the help!!

 

Thanks for the great additional info. I don't think either the 2016 or the 2019 Prius came with a spare tire from the factory when purchased new. We do have the foam pieces that go in the back for both cars, but it doesn't seem like they are the variant designed to be used with a spare tire, I don't think they have a tire "recess" on the bottom side.

Anyway, no problem, I think I can use the parts that I purchased, will get the Yokohama tire mounted on the compact spare, see how it bolts up in the 2016, try the 64993-47110 carrier will full size spare in the 2019, and go from there. Thanks again!!
