I use these tires on my drop-bar fixed-gear MTB conversion during the spring, summer, and fall months. They're not "slick", but the tread is flexible and the sidewalls supple. The tires are comfortable and easy enough to propel that this became my go-to bike for anything from my 7-mile commute, to 25-mile club rides, to 60-mile gravel rides. One nice thing about wider tires is that they take longer to wear out, but I'll definitely buy another set once these do. The tan sidewalls make them look classier than other MTB-sized tires in my opinion, and I'm happy that Panaracer still makes quality tires in this style.
