Safe to keep ridingWarning sign
Tyre Losing Pressure
A tyre that's gradually going soft, rather than suddenly flat.
What's happening
The tyre feels a bit softer each time you check it, rather than being completely flat — a slow leak rather than a sudden blowout.
Likely causes
- •A slow puncture from a small piece of debris
- •A worn or slightly loose valve
- •On tubeless setups, sealant that's dried out and needs topping up
What to do
Safe to ride short distances at reduced pressure, but check before any longer ride — a slow leak can become a flat mid-journey.
