After returning the undersized 700x35 4Titude tires and exchanging for 700x40 I figured I should update my review. The 40's are also undersized measuring 36mm. Since I was originally looking for a 35mm width, I'm okay with the size. That said, if you're looking for volume, go with the largest size offered, that being the 700x42. I've only put two rides on the tires so far and both were on relatively decent pavement. The tires rolled fast and had good grip. I think they will do well on the dirty road and hardpack rail trail rides I intend to use them for. I don't think I'd use them on anything looser than hardpack gravel. I'm only giving 4 stars due to not being true to size advertised.
