I have 55mm wide 700C slick tires (Rene Herse Antelope Hill) on my touring bike. Mainly because I can fit them.
At some point, toe overlap might become an issue.
Most road bikes are going to limit you to about 38mm or thinner. If you need something wider, you can get 650b wheels, and they might (depending upon your frame) permit you to squeeze in about 5 or 6 mm wider tires.
