ii'm running et38 wheels with 215/40 with fairly low car and everything is good. from aesthetics it would even require some adapters to bring wheels more out of the arches.
i'm using 7" wide wheels, but that 0.5" is not playing that big of a deal.
i'd say go for it and it will look great and handle beautifully
