They're only about the width of the tire, and they appear to be positioned to displace that tiny bit of air before it hits the tread.
I also have a terrible time posting photos. I’m not sure why that is so difficult to do on Ecomodder. Without a photo of yours Meteor, I believe we are talking about the same thing which many have called “spats” on this site.

From a different thread, I just learned that we may be using the term “spats” incorrectly going as far back as 2010. The correct term should be “tire “deflectors” so for myself I will drop the term “spats” going forward.

There is a component of lift as the front of the tire is exposed the oncoming air and is forced out to the sides. The mini air dam or “spat” in front of the tire should divert some of the air around the tire more smoothly. Some have suggested that car manufacturers may use them to cut down on noise as well.

I will try to find a link to a photo in another thread.
