This doesn't really both me either. Look at the dynamics. You don't have anything but the floor to burn, correct? You don't have an upper layer preheating the tires. Tires don't turn to a flammable liquid pool fire as easily as plastics. Yes, tire/rubber is a little harder to put out once going. Heat/ fire go up and out. It doesn't spread to the side very easily in solids. All that said this should be a very easy scenario to take outside and light it on fire. Serious, do a test. See if you can get a sustained fire. And if so see with just a little water if it stops spreading. Remember a successful fire is a contained fire not a suppressed fire.
Oh and BTW the best you can do is not 0.2/1500 with 13 psi safety. Just a quirk of mine...carry on.
