Generally speaking this could be about advantages/distvantages between smaller and bigger wheels, if you want.

I'll start with some of. Please improve/correct this lines, thank you.

16? or smaller
Advantages: lower price; within regulations when imperative; less weight; the car is quicker on short distances; more manageable; higher profile for the tyre if needed = more protected on bad roads; less stress on suspensions;
Disatvantages: less clearance for bigger brakes; tighter tyres = less adherence/ less braking surface;

17?
Advantages: more aesthetic; more clearance for bigger brakes; wide tyres/low profile tyres mounted => increased stability/ better adherence/ bigger braking surface;
Disatvantages: higher price; more stress on suspensions; higher car sitting; more weight; slowing down the car on short distances;

Some aspects can be relative and the comparison is supposed to be made between different sizes of same rim. The order isn?t necessarely relevant.

Cheers,
Cristian
