I had a motorcycle tire the other day just go out on me, it was 2 months old and had less than 200 miles on it, I didn‘t have anything stuck in my tire, and I really couldnt‘ tell you what happened, all I know is there‘s a huge straight line cut in the tire. Anyways, Michelin says they‘ll replace it no charge if it‘s a defect. So what exactly is a defect that could happen, and what could be an explanation of what I‘ve experienced? I‘ve never had anything like this happen before. A nail in a tire or something else is pretty common, but this is new to me.
If it is parallel or perpendicular to the rim of the tire and the same depth all the way around then you may have a defect. If it is an angled cut of varying depth then not likely.
It could be a flaw in the manufacturing of the tire. This would possibly form a separation. What this is the inner liner comes loose from the tire carcass and air seeps in and cause a lump. Did you have any vibrations before it went? Also you could have ran over something that sliced the tire. Hard to say without looking at it very closely.
