I think the aim in terms of making a car better/easier to drive its better to have smaller wheels its usually just the better looks that make the manufacturers go for bigger wheels. Wider wheels will offer more grip but you then risk tourque steer from the front. Also increasing the radius of the wheels means fitting lower profile tyres which harms the ride and probably inteferes with the gearing as well due to the increased rolling radius of the wheels. In short bigger wheels usually look great but will never help performance
