I only have about 4-8 sessions remaining on mine. Not sure what I will replace them with.
Since, I only have 4-8 sessions remaining on this set, I went ahead and purchased a new set through Discount Tires Direct. I will also have them heat-cycle this set, which I have never done before. If I develop the splicing issue again, I will have them do a warranty replacement.

Has anyone that did the heat-cycling also had this issue with tread splice? I was told by a friend that if the tires are properly heat-cycled, this will not happen. Mine were not because I first ran them on a wet/damp track day?
