Agree, can easy get 225/40 on a 9, ive seen far FAR less, but dont think itd look right on a cossie unless it was the widest tyres thatd go under the arches.

Very cool wheels, id try n go as wide as you can just cause you get more dish on em.
Ie none on an 8, a bit on a 9, and a fair wack on a 10.

Heres my car on 10x18s.
