Tires selection is often tough to get right. I have been experimenting with tires in road, cyclocross, and mountain biking, but I have gained the most experience with road and road tubeless. Simply put, it is the riding that I do most often, and the people I ride with and get advice from ride lots on the road. I have found that I really liked the 25 mm tires after coming from the smaller 23s. When I had 22s on a set of old tubular wheels, I found them to be almost unrideable.
