PHOENIX -- Need to borrow $20 but can't find a friend to loan it to you? You may want to ask Bruce Halle.
Of course, we kid. But Halle is reportedly the richest man in Arizona with a net worth of $4.8 billion, according to real estate site Movoto.
A Forbes profile listed Halle as the chairman of Discount Tire, the world's largest wheel and tire retailer with more than 850 stores in 25 states. His company owns the Guinness World Record for the longest-running commercial spot, one every Valley resident will recognize.
Halle, who lives in Paradise Valley, is involved in the community. His Bruce T. Halle Foundation supports several local causes, and has established a family justice school at Arizona State University and the nation's largest school for homeless children.
Who knows? Maybe he'll pop for more than $20. After all, Forbes said Halle is the 336th richest man in the world.
