The CST C51 is a 12½ × 2¼ slick for balance bikes and small kids' bikes — a smooth tread that rolls easily on paths and driveways, on a tough wire bead.

Highlights

  • Slick tread — easy rolling for balance bikes and first pedal bikes
  • Wire bead — simple to fit, hard to damage
  • 12½ × 2¼ (ISO 203) — the common balance-bike size

Fit and compatibility

12½-inch (ISO 203) rims; run with an inner tube. Check the size printed on your old tyre's sidewall.

Need it fitted? Tune Cycles can fit and true it in the workshop, or ship it to your door.

CST backs its tyres and tubes against defects in materials and workmanship, assessed while serviceable original tread remains. Road hazards (cuts, snags, punctures), plug repairs, under- or over-inflation, overloading and incorrect mounting or rim fit aren't covered.

For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim with the distributor for you. This cover is in addition to your rights under the Australian Consumer Law.
