Enduro tyres and mousse: choice and pressure

The tyre is the single biggest traction lever on an enduro bike - bigger than any clicker. Get the pattern, the carcass and the pressure right before you chase suspension.

Tread and terrain

Soft and muddy terrain wants a soft, open, gummy knobbly (FIM-type soft compounds) that bites and clears. Hard, rocky, dry terrain wants an intermediate or hard-terrain pattern with more, closer knobs and a tougher carcass to resist tearing and pinching. A trials-style gummy rear is the hard-enduro weapon for extreme rock and roots where pure mechanical grip beats knob spacing.

Mousse vs tube

A mousse insert removes punctures and lets you run an effectively very low pressure, which is why it is standard in competition. Its downside is a fixed feel that softens as the mousse ages (treat a tired mousse like a flat - replace it). A tube with a rim lock is cheaper and tunable but exposes you to pinch flats at low pressure, so a rim lock is essential once you drop below about 0.8 bar.

Pressure

Low pressure enlarges the contact patch and lets the tyre conform to obstacles. With tubes and a rim lock, roughly 0.5-0.8 bar is the working off-road range; run the front slightly lower than the rear for front bite and compliance, and add pressure on sharp rock to protect the rim. With a mousse the pressure is fixed near 0.8 bar equivalent. Always weigh traction against pinch-flat and rim-damage risk for the terrain.

These are starting points - terrain, temperature and rider weight all shift the ideal, and setup is never a safety guarantee.
