The Surly Dirt Wizard tires are like magic for mountain biking. They're all about giving you amazing traction and control on those tough, low - traction surfaces. The center tread has a double row of aggressive, beveled knobs that gobble up the trail, while the well - spaced, siped knobs dig into loose corners. Designed for 50mm rims, these tall and wide tires offer top - notch traction and cushioning. Their flexible and responsive casings are also durable and supportive. The minimum outer rim width for these tires is 35mm. With an ISO diameter of 584 (650b / 27.5'), they come with tread and sidewall flat protection. They have a TPI of 60, are labeled as 27.5 x 2.8, and come in a stylish black/slate color. They're set at 40 PSI, have an ISO width of 71mm, and are perfect for mountain biking. Weighing 1250 grams, they're tubeless ready clinchers with folding beads and a 27.5+ diameter.
Using the Surly Dirt Wizard tires is easy. First, make sure your rim meets the minimum outer width of 35mm, though they're designed to work best on 50mm rims. Mount the tires onto the rims and inflate them to 40 PSI. When riding, you'll notice great traction on all types of mountain trails. As for maintenance, regularly check the tire pressure to keep performance at its best. Inspect the tread and sidewalls for any signs of wear or damage. If you get a flat, since they're tubeless ready, you can use a tubeless sealant to fix small punctures. Avoid riding over sharp objects as much as possible to prevent major damage. Also, clean the tires after muddy rides to keep them in good shape.
