Ok Griz, here you go. I put it on when the bike had 5,499 miles, it now has 10,262 so that's 4,763 miles. I didn't measure the tread depth when new (wish I had). Now it measures ~ 6mm. It's hard to measure and the angle wasn't right. It looks like it's 4mm deep but it's 6mm. I also did the quarter for perspective.
Hope this helps:
