Sorry to hear about your problems. While I can't help you get better service I can offer some observations on tires & tire failures.
I note that you apparently had one tire of a set of duals fail and replaced the failed tire with the spare. You later had the mate to the original tire also fail. There is a very good reason that the reason the 2nd tire also failed was that when the first tire failed it transferred the load it was supporting to the 2nd tire.
Another possibility was that the spare was not of proper dimension. That being +/- 3/4" in OC. Many times when one tire in a pair fails it is suggested that its mate also be replaced due to probable damage. or at least have the "good" tire dismounted and completely inspected by a dealer that sells that brand to confirm it is not damaged.
You didn't make any mention of having any warning from your TPMS. This raises my suspension that you did not have a TPMS which is one reason you did not know the 1st tire was loosing air prior to it failing.
It has been suggested that people check their tire size and confirm it is readily available. If it is an "odd" size then they need to consider carrying their own spare. Don't need the wheel as service trucks should be able to change & inflate tires by the roadside. Of course that assumes you can get service. But maybe if you do not need a tire it might be easier to obtain service in the first place.
Back to TPMS. Running these systems can easily pay for themselves. First it may provide early warning so you can safely pull off the road before the tire comes apart. Second it might save the price of both tires by preventing you from unknowingly driving on under-inflated and overloaded tires.
