I have 16's on my hatch, I am currently riding A520's but I want azenis. The closest size that I can find are 215/45. Does anyone ride that size because I question if they will rub. If they do I'll probably have to get 15's.

 

They will rub. Try the ES100s... I've been told they're a great tire. Not quite what the 520 was, but damn close.

 

try the dunlop fm-901's they have the same treadware but are a little road noisy on the highway, but so are the azenis
