that is a false question. less rubber on the road means less friction and this calls for better fuel economy
maybe, efficient means high-performance, with a good grip and braking characteristics. Wider tires also mean better handling.
The angle narrows as speed goes up
Your question makes the assumption that the question is true. Wider tires are not more efficient than narrow tires at normal speed in all conditions. Wider tires do provide more traction and stopping power on dry or wet pavement as they have more tread contacting the road. But a wide tire that is worn also has a higher tendency to hydroplane on a wet road than a narrow tire. In snowy conditions a narrower tire is almost always a better choice. Wide tires tend to float over the snow instead of digging in and they usually provide less traction. Wide tires also may provide less fuel economy than a narrow tire. It depends on many factors.
The usual antonym of narrower is "wider."

"E" and "D" do not actually stand for anything . . . the width of shoes is measured, "A, B, C, D, E" and so on. "D" is standard normal width. "C" is narrower, and "E" is wider.
It's not that easy to tell. Generally, a thinner tire will be more aerodynamic than a wider tire, but there's more to speed than aerodynamics - rolling resistance for instance. A wider tire with less rolling resistance can be a faster choice than a narrower tire with higher rolling resistance. And there's tire pressure too. With a narrower tire, you'll need to run higher pressure to avoid pinch flats. With higher pressure the ride gets bouncier. And each bounce will turn some of your speed into an upward motion, losing you both speed and traction for the moment.
