Spare Tire

you could try ebay, or if there are any salvage yards nearby. there should be no shortage of junked prius. i don't think full size will fit, but i could be wrong.
you should be able to get all the part numbers and specs from a dealer parts department.
it's just a standard scissors jack, but you couldn't go wrong if you can find a descent aftermarket, the oem is pretty flimsy.
i hink you jack on the pinch weld under the rockers, it should be in your owners manual.

 

The tools and temp spare rim info:

Standard tool for Toyota Prius ZVW30L - Auto parts - Amayama

Disc wheel & wheel cap for Toyota Prius ZVW30L - Auto parts - Amayama

there’s also a plastic cradle, holds the tools and sits inside the spare rim. Dealership should at least be able to confirm what you need.

Temp spare tire size is specd in owners manual. If manual is missing pdf can be downloaded from Toyota Tech Info site.

I can pretty much guarantee a full size spare won’t fit.

 

I have a full size spare in my Prius.

 

I'd wager the hatch floor sits an inch or two higher.

 

What you see in the picture is how I have it, the trunk floor does not raise 1" and lays as it should.

 

With the black plastic sub-floor tray missing.

 

Yes as you see it without the black plastic sub-floor tray.

 

Size of aluminum wheel?
Tires?

 

It is a an OEM 15" and tire is 195/65R15

 

OP asked a simple question in post #2.

You shoehorned a full-size spare in there, which rides high both due to chafing the sidewall and the tire's increased width, and to compensate omitted underfloor tray and tool cradle, likely leaving the hatch floor unevenly supported.

I've tried dropping a full size tire/rim combo in there, know what happens.

 

at least we know it can be done if that satisfies your objective

 

No need to use a shoe horn, it was not a tight fit and has space around the tire and goes in and out very easy.

The hatch floor has no problems staying in place as normal. I often have lots of things in the trunk with no collapse happening.

 

Well I learn something every day.

 

The complete specification of the temp spare tire, and the regular tires, is shown in the Owner’s Manual. They’re both about the same, within maybe 1/8”. The stock 195/56R15 is (theoretically) 25” OD.

Have you got the Owners Manual? If not there’s PDF available, from Toyota Tech Info for one, under the Manuals Tab.

From whom? Yo relied on them to spec the rim, size the tire?

my 2 cents: get the Toyota spare tire rim, buy and have mounted the correct spec temp spare.

FYI: Toyota changed the temp spare spec for Gen 4, but for inexplicable reason: the stock tires and rims have identical specs to Gen 3. Also, Gen 3 spec (16” vs 17”) is actually closer in OD to stock (195/65R15).

 

It's just smart to want a spare in case of a flat. I found a good price on a donut spare for my 21 Prius but didn't have any luck trying to find one for my wife's 24 Corolla Hybrid which has 18 inch tires. (Over $400 for a donut) so just bought a full size steel rim and tire for just over $200.. Her trunk is huge, though, so not too intrusive and it's just us so we don't buy huge hauls of groceries at one time, anyway.

 

There's a phenomena 'round here, not sure if it's widespread, nor why:

I was thinking, having a car that's build date is a solid 15 years back, to replace our temp spare tire. I contacted our loca Kal Tire outlet, asked about it, and they just shut down the conversation, saying in a nutshell "we don't do temp spares". Not sure why that would be. Thoughts?

I suppose I should contact a few other places, but seems weird. I get a hunch no one ...ever... replaces their temp spares, at least not for "aging out".
