Changing my rims to a smaller diameter

[vincentg]

I want the suggestion of the yaris world peeps.

I have an 07 yaris (dark grey - almost black) and the rims are rota type 17' wheels - pictures below - and i wanna switch to a 16 or 15's cause its really bumpy here in the Philippines.

Perhaps you can tell me what kind of rims i should be on a look out for. That can fir nicely into the yaris since i dont have that 'eye' for rims.. Awhile ago my neighbor was offering me his rims and i didnt like the way it looked so i declined, shortly after, his friend passed by and tried the rims on and it looked soooo good.

So maybe you guys can help me look for like what design, color i should look for.

Thank you YW!
