Before ordering and fitting

Match the size printed on your tyre sidewall and check the valve type and length against your rim and existing tube. Schrader valves require a compatible valve hole; do not assume they fit a Presta rim.

Check the tyre and rim tape for damage before fitting. Lightly inflate the tube to give it shape, then fit it carefully without trapping it under the tyre bead. Inflate within the limits marked on the tyre and rim.

Self-sealing tubes help with small punctures but are not puncture-proof. Large cuts, damaged valves and other failures may still require repair or replacement.
