Ok well I decided a long time ago i am not going to just rely on people to explain what the hell my tyres are doing but to learn it myself. Hope this small contribution will give you the push to do the same as I have year ago. I've have had to do quite a bit of suspension work while owning motorcycles to keep the cost down if there is such a thing. As a person that researches as career it wasn't to hard to read and find some material that was useful. I wanted to share some of the findings that i came across and hope that it can help others in there suspension plans or education that they wish to learn and teach themselves.
Now these are extensive displays of what can happen to your tyres but overtime (if not on the track) tires could look like some of these in some minimal degree.

Pictures are in order according to the working attachment:
1 COLD TEAR
(potential rebound tear)
These markings are indications of the tire having too much air so that the outer skin cannot reach the required temperature. The tire is probably gaining only 3-4 pounds when it comes off the track. It can also indicate incorrect rebound adjustment in both front and rear tires, so tire pressure gain must be checked immediately after getting off the track. Gain should be 5-7lbs from cold to hot.
2 SHOCK SPRING TEAR
When the shock spring is too soft or too hard, the tire carcass is put under extreme duress to the point where the tire shreds and melts. This can be determined by measuring sag to see if the target number cannot be reached firstly, without considerably adding preload to the spring or secondly, if all the preload is off the spring.
3 SHOCK REBOUND TEAR
When the shock rebound adjustment is incorrectly set on D.O.T. tires, the tread pattern will show cupping on the leading portion of the pattern with a raised edge followed by a low spot immediately behind it.
4 HOT TEAR
When the tire has too little air in it, the pressure gain from cold to hot will be in excess of 10 pounds. When this occurs the tire melts and leaves an angled pattern yet a solid edge on the outer area of the tire.
