Center hub cap question

[Rylee]

I have a 2016 special edition so that being said I really like my stock rims!
But I would like to put a trd hub caps on them but I can't not find the right size

Do you have a set of calipers? For measuring.
Hint: Harbor Freight $19.99
You can take the wheel off and measure it from the inside.
