Aldermog was developing the dreaded "bumps", I looked and found as you did. I was planning to remove the steel screws and replace with aluminium or titanium, until I realised that I'd have to remove the silencers. So the job was left for the winter, but instead we traded the car in against Tarka.
Tarka has no tread rubbers, just protective paint film...
It has got scuffed, you can't polish it out so may have it removed and perhaps replaced.
Why "perhaps"? I'm beginning to wonder if simply naked running boards might be best!
