"Hire" is used differently in AmE. We only hire people, not things. In BrE, they (as Tdol mentioned) can hire machinery or a car, to name a few examples. That sort of activity is always referred to as "renting" in AmE.
Examples:
They hired five more assembly line workers at the Ford plant.
My car is being repaired, so I had to rent one for the week.
Instead of promoting staff from inside the company, they hired a new person for that management position.
My living room carpet is a mess, so I rented one of those industrial steam cleaners for a day.
