The Mainlines are our trail tires but they also make durable street tires. Available with wire beaded mid-weight, high pressure casings. The 2.20” has a micro knurled surface on a directional tread designed to go on the front or the rear. The 2.40” size is designed specifically as a front tire but could be used in the rear if your frame allows. Available in 20” and 22″ sizes.
