17mm hex to 18mm square adapter

[XashBE]

So i wanted to get me some new road tires for my Asuga.
And i finally decided on the GWX05-XM3 and now i see they come with an unusual 18mm square fixing. Well F me...

You can find millions of adapters to make hex bigger, smaller, 8 sided and so on. But square? Haven't found anything, let aside in the EU.
Only thing i found was a YT video mentioning a CNC guy from Greece/Europe called "Brushlessmanic". With the video being 7 years old, even google couldn't help me. Anyway, i need something like this!
Anyone know of a place (in the EU) where i could get such an adapter? Or has an idea on how to fix the issue?

Thanks

sorry dont reside in EU.but in a jam I've used shim stock cut small strips to makeup the 1mm difference. I also ca glued them in place.

There are ways, sure. But it's gotta be pretty as well

Yeah okay, seems too much of a hustle to get this decent. Yes, there are adapters out there but they cost as much as the wheels...

I just went for hoons silver and accept having slightly smaller wheels.
