Answer
Both frictional and safety considerations are noted here. Drag-racing cars are smooth, in order to reduce friction and wide in order to have proper wheel base. It also helps to keep balanced at higher speeds, while passenger car tires does not have high speed requirements. So, the tires are narrower and treads are provided for proper friction.
Friction does not have a role to play in the difference in surface areas of the tires. It is the safety consideration that comes to priority here.
