I had a trailer tire (Powerking Towmax ST235/80r16 10PR) fail on a recent trip. The tread of the tire came completely off leaving the sidewall intact. When I removed the tire from the wheel to put on the spare the tire was still fully inflated even though I could see the steel belts. I sent the tire to the manufacture, minus the tread. The reply said that "the missing tread made it difficult to determine the operating conditions of the tire. However, there are signs of bead damage likely occurred during the mounting process. A circumferential cut on the inside of the tire along the bead toe may have been the initiating factor leading to the permeation of air into the tire carcass. This migration of air appears to have lead to the complete failure." My question is is that even possible and if so, wouldn't the tire lose its air after the tread delaminated because of permeation of air into the tire carcass. Since I am being offered $125 to replace the tire as a goodwill gesture by the tire manufacturer if I sign a release, I am suspicious.
Any insights would be appreciated.

Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
