Problems with 2015 Ford Mustang TIRES

On a monday morning, i get in my car to go to work and the vehicle's warning sensors start to go off indicating that my left rear tire has only 15 psi. now, only the night before, i was driving around with no problems on my tires so this leads me to believe i must have picked up something on my way home like a nail or a screw. i took the car to the nearest tire shop and when they inspected the tire they indicated there was a bulge in the inner exterior of the tire. when i asked them what that meant they informed me that a bulge usually created when driving through a pothole. i was indicated that it must have been a significant pothole to create such a condition on a fairly new tire but the problem is that i never ran over a pothole. the wheels do not have any bends or scratches indicating it went through a pothole the size of which needed to be significant enough to cause the damage. this is a new vehicle with only 4,800 miles and factory tires. because the bulge is at the sidewall of the tire, the only course of corrective action is the replace the tire.

Ford has failed to make a spare wheel/tire available for the 2015 mustang. it is not standard on all vehicles (a tire inflation kit is all it comes with) and the spare wheel/tire is on back order for all dealerships because supply is low and production is being prioritized over owner availability. therefore, i am stuck without a spare wheel/tire. i have even tried to procure an aftermarket spare and 3 different tire stores have told me they do not have a compatible spare available. ford is handling the availability of a spare wheel/tire as a shortage of an "accessory" as if it is a floor mat, rather than a safety critical part as a spare wheel/tire is. *tr
