Wheel cap?

They come with full wheel covers. The center caps are available in aftermarket. Run about $75.00 a set of four. Plenty of links available on this website.

 

I'm not completely sure, but I believe it's item #6 here:

Wheels for 2017 Toyota Prius | Toyota Parts

It's technically for the 17" rim, but I think it works on a bare 15" rim as well?

Out of stock at the above link, but the part number and description (for searching) is:

42603-52170 Center Cap

Amazon.com (US site) has a set of 4 for $78.70 (USD):

I would concur, you do not want to drive for protracted time without covers, and the centre caps are best at sealing that area, maybe better than the larger overall wheel covers. I drove a few winters here with steel rim snow tires, no centre caps, and the hubs got very rusty, very fast. Wet/salty road conditions here though.

 

This is with the hubcap removed - obviously not designed to be driven this way:


With the wheel covers installed, it looks like this:


I guess if you want it bare, you'll have to buy wheel caps - but TOYOTA designed them to improve aerodynamics, so don't supply un-needed caps.

 

I measured the opening and went on line and bought some plastic plugs for electrical work and hot glued them on.

 

The wheel covers are an aero feature that help the Prius get it's good fuel economy, why remove them?

Also, aren't the wheels aluminum, not steel? I don't remember any Prius ever coming with steel wheels.

 

The AERO feature is pretty ugly

 

Well if you're going with sport car looks I'm not sure why you'd own a Prius.

If you bought the car for it's fuel efficiency, then the aero covers are a beautiful thing...as they say, beauty is in the eye of the beholder.

 

Surprised no Chinese have cloned these $75 a set dust covers yet.

SM-N960U1 ?

 

Took those ugly wheel covers off right away. They look like a rotating pizza.
I thought they were the dumbest thing I have ever seen. Why didn't they just make a wheel that was aerodynamic. Dah!

 

I wonder if the aero wheels from the 2nd or 3rd gen Honda Civic Hybrid would fit?

 

There's Plug-In Prius rims...

Could you post a link? Were they close-enough silver or you painted?

 

3rd gen HCH ran from 2012-2015. The wheels aren't as aero as the HCH2 but they're better than the stripped Prius rims.

There was also a limited production Civic HF with aero wheels, but they look to be the same as the HCH2's.

Would the HCH2 wheels fit if you used spacers? I'm not to versed on the difference between 5x114 and 5x100.

You could get a set of lightweight, unaero alloys and screw on some moon discs if you really wanted to.

 

That's short hand for the spacing between rim holes: 5 holes, and 114 (or 100) mm between holes. So definitely not going to work.

 

Thanks! Always good to learn something new.

Looks like pretty much all Honda wheels are 5x114 other than the 4x100s.
