Tire pressure

The single most adjustable parameter on your wheel. A few tenths of a bar (a few PSI) up or down changes how the wheel rides, grips, absorbs bumps, and how far it goes on a charge.

Too low

More grip and comfort, but: increased rolling resistance (less range), higher risk of pinch flats, potential rim damage on hard bumps, and mushier handling.

Too high

Less rolling resistance (more range), but: reduced grip (especially on wet surfaces), harsher ride over bumps, and the tire can feel skittish in corners.

What pressure to run

Depends on rider weight, tire size, and terrain. A rough starting point: 2.5-3.5 bar (35-50 PSI) for most EUCs. Heavier riders go higher. Off-road goes lower. Adjust from there based on feel.

Check tire pressure weekly. It drops naturally over time. Riding on a soft tire is the easiest way to destroy a rim or lose grip when you need it most. Use the tire pressure tool for a starting point, then tune by feel and terrain.
