Chairman Billy Luster said the vehicles were purchased through state bid for approximately $16,000 each.
“It was time to upgrade the fleet,” Luster said.
The vehicles came equipped with a police package. Luster said all the appropriate equipment should be installed so that the vehicles will be in use within the next week.
The county has also purchased a van for the sheriff’s office that has not been delivered yet.
The van, which will be used to transport prisoners, is expected to arrive as early as February.
Sheriff John Mark Tirey expressed concerns about the state of his department’s fleet in recent budget discussions.
In September, the patrol vehicles for the sheriff’s office consisted of 23 Ford Crown Victorias.
The newest model was a 2010, and the lowest mileage was slightly more than 71,000.
Luster said the Tahoes will be the first SUVs available to patrolmen of the sheriff’s office.
