Rainman and I left his place in East Tennessee last Thursday headed to Oklahoma to ride with friends. On Wednesday I rode from Western NC to his house via Waynesville and I stopped in where I bought my Vision. I asked if the mechanic would check my tire pressure he said sure. Front ( Dunlop E4) and rear (Metzeler ME 888) were spot on for correct pressure. Great. I ride over through the Oconee river and onto his place. Left Thursday morning and were determined to ride back roads and take two days to get to Talihina, Oklahoma even though the forecast there was 100 % rain and it did. About 60 miles from Chattanooga and early the following failure on the ME 888 took place. Temps were average. Load was no more than two up would have been. Speed was 60 ish. To us it looks like a defect in the tire. I managed to get it off the road and didn't damage the rim. Great guy finally stopped to help. He owned a roll back and took me to Crockett Power Sports in Chattanooga that had an E4 rear on the shelf. $500 later, tire plus mount balance and rollback ride 60 miles we were on our way again. Take a look. Tell me what you surmise. This was a new tire, bought this spring. View attachment 500139 I did not run over anything.
