Any other cars with the same 15-in. wheels?

I went with this, when getting snow tires for our 2010. In the fall of 2010 the rims were $70 apiece, and the 20 nuts $31 in total:

Corolla steel rim, part no: 42611-02471 (2003-2008 corolla or matrix, CE, LS, S)
steel rim lug nuts, part no: 90942-01007 (plain, open-ended, galvanized)

As a makeshift centre cap, to cover the hub (it rusts VERY readily if left exposed), I used a 2" ABS end cap. They have an inside diameter of 2.375", which is slightly loose, but I found if I cut a rubber band out of an old bicycle inner tube, and pushed it over the rim's hub opening lip (carefully), and then tapped the cap on, it stays put.

The lug nuts you could likely improve on, either using the stock (which will stick out, look a little odd), or some acorn style if you can find. They all seem to be about 38~40 mm long though, one-size-fits-all I guess. I find the open-ended ones are ok, except:

1. They don't have a shoulder at the base, so you want to be careful putting a socket on, to avoid chewing the paint of the rim.

2. The stud tip is exposed, rust prone. I've adapted by brushing a drop of oil on each one, once or twice during the winter.

They're not purdy, just functional:



I have a set of Plug-In Prius rims waiting in the wings, will likely swap them when this set of tires wears down a bit more.

 

Oh hey:

Since you don't need them till next winter, be patient and peruse the For Sale forum here and auto salvage yards. I have two Prii, each with their own set of snows. For my 2011, I picked up rims from someone who was selling here on Priuschat (I think I paid about $200 for the rims and $100 for shipping) and for my 2015, I found a set from a salvage lot about 100 miles from home (paid $275 for the rims).

 

Look before you leap with the sensors. Maybe you need them to pass inspection in your state. Tirerack has a list of what states require that. If not, consider the "snow tires with sensors" dilemma: you will need to "introduce" tpms sensors to the car, twice yearly. A dealership will charge maybe $75~90 for this, tire places less.

If you're DIY'ing the tire swap, that's a bit of a pain. You can buy equipment to do it yourself too I think.
