How badly does the Maxxis Creepy Crawler mark concrete?

I did a search and didn’t find the answer to this specific question (although this post may be related). After a few months riding my beginner’s 24" freestyle unicycle (and busting parts) I plan to get a 20" trials unicycle. I wanted to know if anyone can share their experience with how much the Maxxis Creepy Crawler marks concrete. In addition to trials I was thinking of practicing basketball on an outside court but am leery to leave too much evidence.
