2016 Prius four Center caps size

Genuine Toyota Prius Center Wheel Caps 42603-52170 Set of 4 2016-2017 Prius (Fits: 2016 Prius)

 

The only cheaper option I know of is to 3D prints them. Or use an electrical plug.

 

Measure the bore with a caliper.

 

If you have the 17’s with the smaller bore I can sell you my take offs. If the are the bigger bore like on my 15’s which are off a 14 you can find them on eBay I paid 20 for a set of 4.

 

I believe the bore is the same regardless of wheel size. It wouldn't make sense to change it.

There's a groove inside the bore, designed to catch the Toyota centre cap jaws. The location of that groove shifted slightly between 3rd and 4th Gen, just enough to make 3rd gen caps incompatible with 4th Gen rims.

 

Interesting. I just know that ones off my 17’s fell all the way into the hubs on the 15’s I put on.

 

We're the 15's Toyota or aftermarket? Aftermarket rims typically have oversized bore, since they're used on various cars. Adapter rings are used to bridge the gap.

 

Hmmm. Same price my local Toyota dealer quoted me. I'm going to break down & pay that one of these days.

Same with the Gen 2. I popped one out of my wife's '07 for a test fit in the Prime. Went right in, but didn't snap into place.

 

OEM Toyota off a 2014.
