Snow tires and switching cars

Deleted (misread your question)

BTW: Google’s AI is saying the Corolla Cross does come with a spare, in certain markets. Australia for one. This is similar to 5th gen Prius, non plug-in version.

 

Why would you want 12 year old tires on your car in winter? Tire rubber hardens with age, and after 5-6 seasons those super-soft snow tire compounds are (at best) the same as all-seasons.

 

You should be okay for the most part. According to wheel-size.com, the hub and bolt pattern appear to be the same between the gen3 Prius and the gen12 Corolla sedan. The offset is a little different(45mm vs. 40mm), but that shouldn't be enough to worry about. And according to tiresize.com, the overall diameter of the tires(195/65R15 and 225/40R18) are virtually the same(25.0" vs. 25.1").

Two caveats: First, going from a 225 to a 195 is a 15% reduction in tire width. That means a loss of some traction for acceleration and braking. Keep that in mind. Second, there's no way for us to know for certain if the brake calipers will clear the smaller wheels. Odds are good that they will since the gen12 Corolla is available with a 15" wheel, but there's no guarantee the trims with the 15" wheels are using the same calipers as the trims with the 18" wheels. The only way to know for certain is to try them and check.



I also agree with what Leadfoot just posted about the age of the tires. I'm assuming(hoping) you're mostly asking about the wheels and you're not still running on the those original 12 year old snow tires. That's dangerous. I'm a big believer in researching for new tires at 5 years, shopping for the best deal at 6 years, and replacing them no later than 7 years from the date code on the sidewalls.



As to what Mendel posted, you can get a spare for the FWD Corolla sedan hybrid, but not the AWD sedan. The floor pan in the AWD is higher and doesn't allow for the spare. Plus the HV connector for the rear transaxle is in the way. I don't think any of the US FWD sedans come with a spare, but you can add one reasonably easily. Not sure about cost, though. You even have the option to use a full-size wheel/tire as a spare if you really want it.


For a full-size spare(FWD only):

At minimum, I think you'd need:
51931-47020 - bolt to hold down wheel
tools
One of your winter wheels/tires should work as the spare. The official size is a 15x6.5J wheel(42611-47450) and a 195/95R15 tire. That's the same general wheel and tire size as the gen3 Prius. The wheels/tires that come with the Corolla Hybrid SE might be a touch wide and make the deck floor stick up just a bit(~1"), but they should still work during the winter in a pinch. Also can't absolutely guarantee the bolt I listed will work with wheels other than the official part number. It should, but I can't guarantee it.


For a perfect install, add:
64777-12190 - goes inside the wheel to store tools and support the deck floor(might only work with the official wheel)
64429-12020 - trim box(don't really know what it's for, but it comes on models equipped with a full size spare - bolts to the passenger side of the tire well)
90119-06786 - bolts to secure trim box (need 2)


For a compact spare(FWD only):

At minimum, I think you'd need:
42611-47631 - 17x4 wheel
51931-12260 - bolt to hold down wheel
T125/70D17 - tire available from places like TireRack
tools

For a perfect install, add:
64777-12180 - replaces the foam in the tire well to accommodate the spare without needing to modify the existing one



The correct OEM tools for both options are:
09111-47051 - jack
09113-42030 - jack handle
09150-42010 - lug wrench
- these tools will fit the pockets in the foam


For a stupidly complete install, you can even add:
42668-58070 - caution sticker that goes next to the compact spare
42668-42010 - caution sticker for the compact spare(50mph max speed)

There's no version of the Corolla that comes with both the 18" wheels and a spare, so I don't think you can get a replacement decal for the driver's door jam showing all the tires and pressures.
