That will get your attention

I zoomed in on his bike and the troublesome muffler frame bracket (mentioned in my previous post earlier) has not let go, been looking at my bike and the std muffler has only got about 15mm clearance at one point, don't know about the Arrow muffler clearance but doubt it would be less, I am guessing he has picked up something that has "miraculously (read what are the unlucky chances of that happening)" stuck/wedged against hanger strap around the muffler and cut the tyre, after zooming in on the tyre I can see it was a well worn Pirelli Scorpion Trail which is the previous model to the tyres I am running which is the Pirelli Scorpion II, I wonder if there was a weakness which may have contributed to the failure?
