Schwalbe Steel Stud Spikes 50 CountSchwalbe offers studded tires for the cold season - these are the original steel replacement studs that come on the Al Mighty.

There are 50 studs in the kit. Separate kits of 50 studs are available for purchase with the tool, although a set of needle nose pliers works equally well as an installation tool. The Schwalbe Al Mighty Studded Tire 26x4.8 has 328 studs on each tire as a reference.4026495898256
