Did I get a Strike after I picked up this spare?

Kinda hard to identify whether or not spare wheel's OEM from a few photos. Why not check with a local junkyard? You might be able to get the deck pieces at the same time

 

Try installing it?

it’s not the tractor yellow of our 3rd gen spare, but looks “stock”: not an oversized hub opening or extra lug nut holes (per a lot of aftermarket spare rims).

FWIW the 3rd gen 16” temp spare is also compatible.

 

It looks similar to the OEM Toyota spare I bought but I'll look at mine (tire size, etc.) and let you know.
FWIW, my wife's 2017 had a flat so I had to use the Toyota scissor jack and it leaves a lot to be desired. I've, since, replaced it with this one in both cars:
AmazonSmile: Amvia Scissor Jack for Car - 1.5 Ton (3,300 lbs) | Car Jack Kit - Tire Jack | Portable, Ideal for SUV and Auto - Smart Mechanism with Ratchet | Heavy Duty Material : Automotive

 

My husband's dad and I tried many different jacks over the years. Their latest development is using a widely available 18 pound 2 ton trolly jack widely available everywhere. The one pictured ia a $33 WalMart Hyper Tough brand.

After pulling the pin and removing the swivel cup, they installed the custom "knife edge" standing seam pinch weld adapter on top pinned in the same was as the original.

It's now completely stable, simple and easy to use.

 

Toyota’s scissor jack has a single eyelet crank connection, cast out of very soft metal. It’s very unstable as you crank.

Honda’s crank connection is a U-shaped bent plate with two eyelets, spaced about 20 mm apart, and better quality steel. Stays much more steady.

 

Toyota's scissors jack, however, does match closely to the pinch welds on the car. The "universal" jacks don't. They will put dents into the lifting contact area which is the PAD that is inboard from the standing seam.

When the Gen 4 Prius with the TNGA chassis was introduced, the pinch weld had a rounded jack contact area and a different shallow slot jack. Since then, Toyota has added a vertical blade to the jacking point, so that the standard Toyoda scissors jack that I have posted in the photo.

 

^ Yeah I used the scissor jack on a rear corner of our 2010 once; promptly dimpled the sheet metal.

Borrowing your pic of the Toyota-style scissor jack:



And comparing to Honda-style:



It's easy to see why the Toyota jack is unstable when you're cranking.

 

Yeah, I have dents from failed test articles trials, too. Those mistakes were a valuable learning experience in developing a true no damage jacking adapter. That's the one that you see in my photo.

 

Since you're test installing the new spare, may as well go ahead and use the jack that you're planning on carrying.
My last new car (2020) came with a spare and one of the first things I did the first time I rotated the tires was install the spare tire with the spare tire jack.
That way, when I'm on the side of the road, at 0-dark-30, in the rain, in a sketch neighborhood I at least know I know that I can change the tire and get on with life.

Good Luck!

 

Have you tried building your foam insert using a canister of expandable insulation foam?
That spare is spot on. Here is mine.

 

Welcome

 

The spare tire situation and the ability to fix a flat reminds me of the situation my dad was in, when the tire had a blow out to a really dangerous neighborhood at night. These were the days before cell phones, when one could call for assistance quickly.

My dad always taught me to be prepared for most all situations.

He conveniently had a trolly floor jack in the back of his van.

It took him only 10-15 minutes to change the tire and he was out of the really dangerous area of town.

AAA, if he had it, would have maybe taken up to an hour or longer. He would have been towed and had to take a taxi home, if he had no spare.

It just makes me think of always having a spare and a good quick and easy to use jack.
