20″ X 2.40″ S&M Mainline BMX Bike Tire- BLACK


The Mainlines are our trail tires but they also make durable street tires. Available with wire beaded mid-weight, high pressure casings.

Available on backorder


The 2.10″ (2.2″ inflated) has a micro knurled surface on a directional tread designed to go on the rear. It also features a center tread with a V-notched edge for accelerating and a flat edge for braking. The 2.40″ size is designed specifically as a front tire. Additional angular raised center tread sections keep the larger, front specific Mainline on the blue groove in turns! Available in 20″ and 22″ sizes.
