I recently got a new pair of Sunday Current 2.25" tires. I thought it'd be a fun idea to dust the raised letters on the tires with a white paint marker. After I hit the letters, I decided to keep going and write some other stuff on the sidewalls. Came out pretty cool. If you're ever going to do this, make sure you get a paint pen with a small tip, mine was large so I screwed up quite a bit.
