Fit Checklist Before Purchase

Before ordering, confirm:

Your tyre sidewall says 27.5 inch, 650B or 584.
Your tyre width is between 2.25 and 2.50 inches.
Your rim uses a Schrader / A/V valve hole.
Your tyre is not cracked, cut or excessively worn.
Your rim tape is secure and covering all spoke holes.
There is no glass, wire, thorn, bindi or sharp debris inside the tyre.
Your pump is compatible with Schrader valves.

Installation Notes

Add a small amount of air so the tube takes shape before fitting.
Inspect the tyre casing carefully before installation.
Fit the tube evenly inside the tyre.
Avoid trapping the tube under the tyre bead.
Inflate gradually and check both tyre beads are seated evenly.
Recheck tyre pressure before riding.
Replace damaged rim tape or worn tyres if punctures continue.

Product Care

Check tyre pressure regularly.
Keep tyres inflated within the pressure range printed on the tyre sidewall.
Inspect tyres for glass, thorns, wire or sharp debris.
Check rim tape if punctures occur on the inside of the tube.
Avoid riding under-inflated, as this can cause pinch flats.
Replace cracked, worn or damaged tyres.
Store spare tubes away from heat, sunlight and sharp tools.
Do not overinflate the tube outside the tyre.
Use care when fitting with tyre levers.
Recheck tyre bead seating before riding.

Warranty Information

Warranty coverage is subject to manufacturer or retailer terms and conditions.
Warranty generally applies to manufacturing defects such as faulty seams or valve defects.
Punctures, pinch flats, incorrect installation, tyre damage, rim tape failure, overinflation, underinflation, heat damage and impact damage are generally not covered.
Tube life depends on tyre condition, rim tape condition, air pressure, rider weight, terrain and installation quality.
Professional installation is recommended if punctures keep returning or if the cause of air loss is unclear.
