Just so you know those are not XR's, you can tell buy the spanner nut.

what would they be then ?

From the looks of them from the pictures they are standard bravos.
You can see the smaller universal and different spanner nut.
The stickers on the sides are from standard bravos also.

thanks for correcting that .
