would anyone have noticed this on their own?

Some people model their hairstyles after celebrities. Detroit Pistons guard Richard Hamilton takes his cue from tires.
Goodyear Tire & Rubber Co., North America's largest tire maker, paid Hamilton to wear his hair in the style of the tread pattern of the company's Assurance TripleTred product.
Hamilton, who helped the Pistons win last season's NBA championship, wore the hairstyle over the weekend against the New York Knicks in Detroit and plans to keep it for about a week, company spokesman Ed Markey said.
Neither Markey nor Josh Nochimson, Hamilton's business manager, would say how much Hamilton was paid. The player also received free tires, Markey said.
