After Sundays ride to the coast on 84 and various roads I discovered the\nrear Sportec split on the left side off of center. Close examination\nrevealed (in my opinion) that the tire cracked from stress. It looks close\nto a scalloping effect. No obvious cuts or gouges from a foreign object. By\ndirection and driving hard out of left turns the tire simply broke-\-and deep\ntoo.\n\nThe meat has maybe a 1000 miles on it. This may be one freak incident. I\nhave not heard of others failing this way. Check your rubbers for ga[\n^ ]ping holes just in case.
