S&M Mainline BMX Tyre

The Mainline is S&M's trail tire.

Available in wire bead only with a mid weight, high pressure casing.

The 2.1 has a micro knurled surface on a directional tread designed to go on the rear.

It features a center tread with a V-notched edge for accelerating and a flat edge for braking.

 
The 2.425 front tire size is a nod to the old 2.125 Comp III we grew up riding in the front.

Additional angular raised sections on three rows of knobs help keep the larger Mainline in front!
