They're not that wide but not skinny either. The front says 2.2 but it is more like 2 in my opinion. The Colony Avenger front tire is really sticky for my shoes. It was a fluke that I got this tire and it has lasted a long time and I will definitely be getting another one. The rear is too heavy but a necessity because there is always a lot of glass where I ride. Lighter tires are thin and then it gets too aggravating getting flat tires. You can keep the pressure high in both tires. Maybe a real flatlander would scoff at the tires, but for me they work OK. They are heavier tires but as Matt Wilhelm said, he learned how to ride flatland on a 40 pound bike. My bike is between 23 and 24 pounds.
