I just bought set of 14x6 Ronal R8 wheels but they dont have center caps. I was wondering if anyone knew what size i would need, or where to buy them?

Also im not looking for the big caps that cover the lugs im just looking for the tiny ones that cover up the center hole.
Thanks!

 

Have you tried measuring them?

 

they are between 2 3/16" and 2 1/4" so by my calculations thats about 57mm, but i cant find 57mm caps anywhere.

 

ronal, ebay and tire rack would the places i would search
