That’s a whole lot of rubbing but seems more likely than other types of damage. You can see the groove skips up over the top tread in places like the object cutting the tire is bouncing on the tire.

It could also be moulding issues on the tread.



This “cut” looks like it was a manufacturing problem rather than damage. The red arrow points to a flaw over the “9” and “0”. The extra printing over the numbers doesn’t match up with the font of the numbers. If the tire were sliced, the little eyebrow over the”9” and “0” are too large to be the result of a slice. The eyebrow over the 9 is particularly wide.



(Green arrow) Have you been taking bike tours of crime scenes? Or did someone try to steal your bike and you “dealt” with them? Is there a mound in your back yard that holds a dark secret?
