Hardpack Trails
If you typically ride smooth or hardpack trail conditions, you will find it best to select a narrower (1.8 to 2.0) tire with a lower knob height and tight knob spacing. These tires are usually found in a round or medium profile. A tire that falls in this category offers less rolling resistance and a smoother ride. If you are a heavier rider or you ride rocky hardpack terrain, you may want to select a tire that is a bit wider (2.0 to 2.2) to minimize pinch flats. A few tires that fall in this category are the Maxxis Larsen TT, Kenda Small Block Eight and Continental Twister Supersonic.
Soft, Loose or Loose-Over-Hardpack Trails
When riding in soft, loose or loose-over-hardpack conditions, opt for a tire with a taller knob height and medium to wide spacing in the knobs. It can often be best to select a front and rear specific tire for these conditions. Using a bit wider (2.0 to 2.35), more square profile tire in the front will offer more cornering stability, allowing you to maintain a round or medium profile tire with less rolling resistance in the rear. However, you may want to stick with a medium to square profile with wider knob spacing to minimize wheel spin. Some tires that work well in these conditions are the Kenda Nevegal, Maxxis Minion DHF and Schwalbe Fat Albert.
Muddy Trails
If you have the misfortune, in my book, of riding in muddy conditions, a narrower tire is your best bet. A narrower tire minimizes the amount of mud getting packed in your fork and stays. It can also penetrate the wet mud on top, allowing you to find more traction on the harder ground below. The type of knob spacing and height can spark debate, depending on who you talk to. Some suggest a wider-spaced, taller knob pattern that will penetrate the mud. Others believe that a lower knob height will assist in minimizing rolling resistance. If you find yourself frequently riding in the mud, try various patterns until you find something that works for the conditions you are riding in. Continental makes a tire called the CrossCountry, which is touted as "the special tire for muddy trails!" You may also want to check out the Schwalbe Muddy Mary, Maxxis Medusa and Bontrager Mud X TLR.
