I don’t know what my edit looks like when you open it in 3.8.1, so here are my settings for filmic rgb:




The big change in 3.9 is color science v6 in the options tab. But it doesn’t hardly make any difference on this photo, so my settings on 3.8.1 and v5 would be exactly the same.
I think the biggest difference between our edits is contrast-based. Of course I can’t compare my edit with any remembrance of the original scene, but I don’t feel my tires are particularly dark. They also look dusty and dirty. For me, your edit looks pretty faded.
Apart from that, I see that you don’t use color balance rgb, which I believe is a pretty essential module to work on your colors.
Also, I see that you have the misfortune of not having a noise profile for your cam. In that case, denoise (profiled) just kills all details of the photo and everything becomes muddy.
But I’m afraid I don’t know what’s the best way for denoising in such a case.
