Domingo Quezada-Hernandez is facing cash smuggling charges when he's scheduled to appear at a court hearing Friday.
A federal criminal complaint says he was arrested Monday trying to cross from Texas into Mexico over the Gateway International Bridge.
The Brownsville Herald reports he didn't declare any weapons, ammunition or cash in excess of $10,000 but officers say he and two companions looked nervous.
When agents saw fresh marks on the spare tire, they had it sent for X-ray screening that showed the cash inside.
