The snakebite must have happened just as the OP was pulling into the garage, because that would cause the tires to flat nearly instantaneously, so there's no way they could have ridden on them more than a few seconds after the impact. Frankly, I'm surprised they didn't notice the impact, because bottoming out the rim on something hard enough to cut through the tube, both front and rear, is more than just a bump in the road.
