You've got a nice round little spot on the tire and a bent plate.If you go out and ride "Hard" make sure you adjust your rear spring to the appropriate level cause if not, this will happen...
I went out and hit it hard today. (I will post VID in a bit) Apparently when catching a little "air" I bottomed out my rear spring causing my license plate to smack my rear tire putting a nice hole in my tire... I only had 600 miles on my tire and now it has a slow leak, FML!!! I won't be riding anytime soon as I just paid up my @ss for college classes, plus My truck and Bike reg is due... So no videos by theRook for a few months On a side note look at the edge of my tire! I was killing those corners! Chicken strips? I THINK NOT!!!!!!!!
It doesn't look to be more than a 1/8" deep in the meaty part of tread. I've had/got gravel stuck deeper than that, just going down my driveway.
I'm not busting on you Rook, I've the deepest respect for you. But I've got to ask the question:
Did the plate touching your rear tire cause a hole deep enough for air to leak out? As fast as your tire must have been spinning, it seems like the plate might have, at the most, scratched your tire. Not made a hole all the way through the tread.
Assuming the plate made that hole, how deep could it be? That's a lot of rubber for a flimsy license plate, instantaneously dragging a tire at high speed, to get through.
I'm thinking maybe the license plate isn't responsible for the air leaking from your tire.
