Pirelli Tire Warranty?? Flat Tire Problem

Yesterday was an expensive afternoon - on our way to Thanksgiving dinner, as we exited the freeway we heard a pop and joy of all joy our rear drivers tire had a flat. It's a pretty major hole in the tread - not something like a small nail hole that could be fixed, it's several inches long. And we have no clue how it happened. We did not see any debris on the road and heard nothing hit the bottom of the car. Has anyone else had problems with their Pirelli 21" tires? There is no warranty through Lucid and no info on contacting the manufacturer for their warranty - I mean seriously the tires have less than 350 miles on them. They should be able to handle some freeway driving. We leave for Vegas next weekend and I am now super nervous that these tires are going to blow out in the middle of nowhere and there isn't even a spare. Lucid has no place to tow it to on Thanksgiving, so today we will be having them flat bed it to the Costa Mesa service center.
