I'm looking to buy some wheels and tires for my black coupe...and i just found this post for sale..

https://g35driver.com/forums/archived-sales/219814-dpe-aristos-sale.html

if the current buyer falls through i'm thinking of picking the set up... but i'm looking to give my car a somewhat aggressive look with the wheels... would 19s be too small? should i go with 20s?

And, if i were to go with those wheels what's a good tire size?

Edit: my car is lowered on some Tein Flex Coilovers...

Thanks!
