C5 Aircross 2025 old style wheel nut covers

[Mathemagic-1970]

Hi all, I need to get a spare wheel nut cover for one that has gone missing. The first lot I bought from eBay were 17mm and too small. Rather than randomly buying different sizes, anyone able to confirm if I need 20mm, 22mm or something else?

Thank you.

I believe the measurement used is the 'across the flats'; to check that measure one of the 17mm ones you bought and confirm which measurement is 17mm. Then take one of your existing covers off and make the same measurement to show you which size to order.

That'll be what I'll need to do - at least I have the removal tool with the set of covers I ordered!

You could also look at the wheel bolt brace to see what size it has on it.

Just a quick footnote in case anyone else comes looking in the future.

The nut covers are 17mm as I originally ordered but the ones on my car have wider tops. The "standard" 17mm tops aren't as wide as the ones fitted.

I ended up buying 5 more on ebay that said they were for "PEUGEOT CITROEN C1 C2 C3 DS3 C4 DS4" but they were the same as what is on my car too.
