ROCKY MOUNT, NC—Emotionally distant, undemonstrative father Earl Kolchak expressed his love for his 17-year-old daughter Jessica Tuesday the only way he knows how: by inquiring about the pressure of the four Firestone Radial tires on her 1995 Ford Festiva. "Are your tires full? You gotta make sure your tires are full, or you'll find yourself in big trouble one of these days," said Kolchak, conveying to Jessica how proud he is of her. "Tire pressure is nothing to mess with." Kolchak took his love for his daughter a step further by personally checking the tires with a hand-held pressure gauge, but later felt embarrassed by the expression of intimacy.
