Racing teams don't use wider tires because they think they might be faster. Wider tires have been shown to have lower rolling resistance, and are demonstrably faster.
Hear hear!
Minimal choices for 27-30mm road tires, and nothing I know of above 30mm other than a file tread cross tire.
FWIW, Michelin Pro4 Endurance tires in 700x25 measure 27mm wide on my Open Pro rims, and I've read that they measure 28mm wide on 23mm rims. I understand that the Pro4 Service Course versions measure about the same.
