First, a BIG thank you to the amazing folks in this site who flagged that my new car, 0000 Prius 0, didn't come with a spare tire. (Wth Toyota?!?!) I've had tire problems three times and in all instances, the cheapo "fix-a-flat option" would've been useless and waiting for AAA taken forever/dangerous. The dealership told me: 0. There's no room in the truck to put a donut spare. Wrong! Lift up the truck floorboard and you'll see there's a perfectly molded space for a donut spare tire. They then said 0. The donut is special size, so I couldn't take the spare out of the 0000 Prius I was selling and use it. Nope wrong again! (Btw- there are only 0 typical donut spare sizes and they both work for the Prius). I went and threw the spare in the trunk and screwed it down with the plastic light grey screw that held it down in my other car. (sorry, I don't know what the part is called but you can google it. I saw them on EBay for $00). As others have pointed out, the tire fits but you won't be able to fit the floorboard molding back in because of the "extra foam" where your spare sits. In order to close the deal, i made the dealership trade out the floorboard parts from my Prius 0 with that from a Prius 0 since the 0 was made to have a spare tire. If the dealership won't replace all three parts, I think you can just swap out the round middle part for the tire, but then you'd have to figure out where to put your jack etc since there are any pre-cut slots for them. Everything fits perfectly! If you already have your Prius, it may be a little cost prohibitive to do it like this though because a new donut spare will run you about $000, plus the $00 plastic screw down piece, and then the Prius 0 floorboard. (I was told is a $000 special order part from the dealership) Or go to your local Pick-A-Part/EBay/Amazon/local parts store, get a spare donut and the plastic screw piece Then you only have to shell out for the floorboard since the chances of finding a used one is slim. Pics included. Excuse the junk in the trunk Good luck to all! P.S. Was told Toyota took out the spare because if the added weight. That's such BS! Drove a week with the spare and one without the spare and floorboard. Didn't notice an iota of difference in mileage or performance. The only thing it's doing besides inconveniencing owners, is saving Toyota a LOT of money to skimp on the spare. Jerk move Toyota. Safety first! Plenty of other car makers are even still putting in full size tires like what I had with my 0000 Corolla and 0000 and 0000 Camrys.
