S&M Speedball Tire Description:

The S&M Speedball Tire features a low profile, micro knurled tread pattern with smooth centerline for minimal rolling resistance. A multi-edge S/M tread design on the shoulders provides additional traction and strong sidewalls offer extra pinch flat protection for those who run lower air pressure. These tires are available in multiple widths and wheel sizes.

S&M Speedball Tire (Black) (20") (2.4") (406 ISO)
These are the best 110 psi I have rode on!! Better than Sundays 100 psi currents!! They grip the road I ride on to push me faster!! Fells like I’m floating on clouds.
