We have all seen them, and I bet allot of use have used them. These tires, are my tried and true commuter tires. I have them on my 1972 Atala Fixie. I used to run the 35mm performance tires, but I wanted to go faster so I went with the Forté GT2 Kevlar Road Tire. I ride the 28mm size and it really fits the bill. These are long lasting tires! I actually always replace them before they even wear out. I sometimes ride the C&O with them and they seem to work well there as well. Now you are not going to want to lean these into a high speed corner cause they don't have that rubbery grip like your race tires. The good thing about these tires for mileage folks or heavy ones like me, is the big bulbous center that packs allot of rubber. This gives the tire a smaller faster footprint. Since the center is so tall, the tire doesn't get that "flat" section that us heavier riders get on the back tire. The sides have a chevron file pattern that works well when you encounter the winter road grit that comes and stays after the first snow storm. The Forté GT2 Kevlar tires being on sale for about 10-14 for the Kevlar version, and like 7-10 for the regular I don't even rotate my tires, I just put new ones on. Now my biggest criticism of the tire is that when it does get cut it can catastrophic, once the a cut is started it fails. I have been riding these tires for 2 years(about to put on a 3rd set) and I have only had two flats!(and that is going to work on K st. to SE DC). Next time I will talk about some sexier tires, but if you want reliable these tires usually fit the bill.
