Depends on whether you're referring to aesthetics or performance.

Yes, 285/30s would be smaller in diameter than stock. Whether or not that bothers you in terms of looks is a personal matter. Whether or not that bothers you in terms of performance (increased rubber on road vs additional shorter gearing due to smaller overall diameter) is dependent on your performance needs.

Personally I don't mind gearing the car a little shorter.
