NHTSA Complaint #11679983 — 2016 FORD MUSTANG

My tire is a 255 / 40 ZR 19 model, speed rated 100W. While rotating my tires I noticed catastrophic tread separation on the inner sidewall of the tire. The separation is scattered, not all in one section, and in total covers about 1/4 of the total diameter. The underlying belt package has separated and steel wire is plainly visible at distance. The tire was still holding normal pressure at the time of discovery and there was no indication of the separation from any pressure devices or anything other than visual identification of the issue, which was only possible due to a routine tire rotation. Driving conditions since installation of the tire have been ~85% dry weather at speeds no greater than 85mph. A long haul trip from San Jose, CA to Los Angles, CA (~675 miles round trip) occurred 1.5 weeks prior to discovery.
