Feel like a chuck wagon cause I'm on twelve horses
A Chuck Wagon was a wagon used to carry food and supplies while the settlers were traveling west. By this Pusha is referring to how his car is always carrying the goods(cocaine). Most of these wagons were heavy, so 12 horses would be enough to pull the wagon.
But by 12 horses, he’s stating that he has 12 different rides to go around in.
12 horses may also mean a V-12 engine. A V-12 is referred to later on by Ab Liva
