Cause of bulging Kenda Kwest
After cutting into the tire and peeling back the layers of cords, I discovered that a bunch of these cords had "slipped" or become unglued, allowing a section of the tire casing to "go slack", causing the tire to bulge under pressure. You can see the bare spot against the outer rubber, where the cords slipped, causing them to bunch up, slack on the right. It almost looks like the glue used to hold the cords is not strong enough or that it breaks down after time and/or use. I was able to peel back this tire casing with only moderate effort. The glue was still sticky but was not holding fast. This tire had 4200 miles on it.
