for efficient dynamics purposes mainly. there are virtually no downsides having narrow tires compared to wide ones providing that the diameter is big enough. the contact surface can be the same or greater compared with wide tires with smaller diameter thus the road holding is not in jeopardy here. the upsides are lower rolling resistance, lower aerodynamic drag and lower up-force presumably, aquaplaning is less likely to occur as well. Decreased non suspended and rotational masses are also a benefit of that solution. There are packaging benefits too.
