You've confused Celsius with Kelvin. The gas laws all assume temperature in Kelvin. I's closer to a 10% increase in pressure due to thermal expansion. Frankly, not as much as if you were riding on hot asphalt in the summer. I vote for defective tire and/or installation. BTW, to the OP, you're much better off that it blew in the car, than if it blew on a high speed turn.
